Help please, 8 plants already dead, one left :(. yellowing or n def. or sumthin

HELPPP please...

i had 2 bluecheese and 4 shaman and 2 churches and they are ALL dead, except this bluecheese which is on the way.

I really cant figure out what is wrong with them :(.

a week or so ago it was fine n all and now its half dead.

im growing in 1cm RC cubes under a 250 metal halide, air circulation is good and temp is between 22-24c.

A+B iconic @ 1/2 strength,
oxy-plus - 10ml/day {tank is 20L}
nytrozyme - {as directed on the bottle}
gurdian angel - {as directed on the bottle}
superthrive - {couple of drops in tank}
canna trichoderma. foiler feed 2-3 times per week

the rest of the plants died befor i started adding nytrozyme, guardian angel, superthrive, and trichoderma to the tank so i guess they have nuthing to do with it.

this bluecheese was the youngest one of the lot as i added it round 2 weeks later than the others and it was holding up. till a couple of days ago.

i strated off flooding 1x a day, moved up to 2x and now i have dropped it down to once a day.
========

lower {older i think} leaves start to yellow from outside and work their way all over, and it happens rappidly over a couple of days, then the ones above them start to do the same and now i can see that even the top are starting to yellow on the edges tho its very slight.
the plant has not grown at all for about a week, since the lower ones started yellowing.


the yellowing is really bad on the lower ones.
stems are dark purple which i think is just normal.
i have already removed 2 lower leaves as they just got tooo yellow and they were the biggest leaves on the whole thing.


i have no idea what to do please help.
iv flushed it today with superthrive/guardian angel and about 1/3 strength nutes to see what happes.

any suggestions or ideas please, need help fast.

they look thirsty to start

fill out the form

E- indoor
E- hydroponic
E- 1cm rockwool
HCL-Hydro
E-Water source is tapwater
-Source water pH is around 7.5 tho i ph it down to 5.6 to 6.1 at all time {i aim for 5.8}
E-Age of plant around 2.5 weeks
E-Rate of application (1.5 ms)
E-Lighting source and distance from plant = 250 metal halide about 90cm
E-Air temperature (daytime between 22-25) and night around 19-20.
HD-Reservoir temperature no idea but its pretty cool.
E-Air % Relative humidity no idea.
E-Lighting schedule - 18/6
E-Type of ventilation your room has : big fan that keeps things in motion all the time.
TR-Did you pre-soak your media in pH corrected solution? yes..


i hope iv filled it out properly. but iv got all the information at the top anyway. pleasee help.

its almost dead but i wanna make sure that it doesnt happen again or at least find out what it is, i suspect it is nitrogen def. but dont know how to cure. :mad:
and all the plants get to the same stage very healthy and very good and then start the same pattern and die off the same way :(.
and iv just calculated iv gone thru around 20 plants now :(.

filled out the form, they cant possibly be thirsty tho. i feed them once a day, and at points was feeding twice, til i noticed they were a lil droopy.

oh n the way i feed them is kinda like flood and drain, i dip them in a nutrient tank for about a min or 2, wait till the water mostly drains out over the tank, n then move them back to their place where they can drain the left over while sitting.

When you foiler feed 2-3 times per week is it during light hours ? It should be at dark.
I never foiler feed till recently and I killed everything, about 20. Only did it a few times and things looked great. Then bam all started to turn just like yours.

Also had a cold blast on hydro water and they turned yellow almost over night.

The other thing is ventilation ? Are the getting fresh air or just push around air ?

Your not getting them enough water most likely. Do the ebb and flow or you could drip back to rez But they need more water. I run drip 130gph pump wide open on 6 plants 24/7. Those rocks do not hold water like hydrtron or all rockwool.

yea when i was foiler feeding i did it under light, tho there was no heat problem therfor i dont think it was a problem tho i remember the leaves got a bit paper like but after a while got back to soft.
how did urs die, did they keep getting yellow till eventually they look like they shrunk real bad?

ventilation is good i say because they are in a built in closet and the door from the other side is always open, therfor air comes into the closet from the side and the hot air gets pushed out thru the top as there are holes in the uper side, so it circulates new air and not the same air, and that room is open to 3 different rooms that have open windows so air and temp are no problem, im giving them plenty water, as when i water i flood them as i have a nutrient tank/tub which i dip the whole pot {till about 80% from the stem in order to keep the top of the root dry} and then i take them out after soaking them for about 2 minutes 80% fully submerged, i was doing that 2x a day n now im doing it once as i think i was overfeeding them, i dunno man its pissin me off cuz iv lost so much and now i have the final set of about 6-7 plants which i just germd bout a couple of days ago and i have a feeling the same is gona happen.

we need a plan lool.:rastasmoke:

Are you growing in a grow tent?

If so read this http://boards.cannabis.com/plant-pro...-anything.html

symptoms look very familiar......

If you are killing everything in your growroom, different strains, different occasions. I would guess its enviromental.

Subzero :)

Top leaves look very dark green, and bottom leaves dying of, and curling I would probable say nute burn...whatever volume of nute you have in your res, I would pour an extra bit of ro water in to dilute it down to like 2/3 of its original strength. And maybe even before that I would flush with 1/4 strength nutes to give it a good flushing. Good luck

transplant into a fresh quality soil asap......no more anything except ph correct water (for soil). i'm sorrry but i do not see that plant surviving your hydro regimen which dseems to include everything but the kitchen sink and simply speed death along. transplant. And pray.

good luck

iv got no soil for one , nd on top of that this problem happend b4 i added anything, i was just feeding them on 1/2 strength n it started happenin, so it wont be ph or nutes, as ph isnt allowed to even cross 6. its always round 5.8 which is bang on.
and i even slowed the nutes down to 1/4 n still the same shit, n that was after flushing.
the extras are all top items, that are good for the plants n help out in stress. n guardian angel is for pythium as i thought that was the problem at first.

hey smooth, i already did that, and i was running about 1/2 strength and the plants b4 that, i had them runnin at 1/4 n the exact same thing happend.
its not nut burn as the leaves are not showing signes of nutburn, ie: the burn.
its showing exactly like N def or lockout.
and iv flushed n etc... same shit.

your title was please any help. that was mine. I'm sorry you seem to feel I have no clue in what iam talking about regarding growing and hydro but its YOUR half dead plant so ....... .I only enough energy for serious listeners........peace out dude goodbye :hippy:

A mother plant I got from a bro of mine. Didn't look too good so I had this foliar feed spray. I mixed it light and sprayed it on every couple of days. They looked great untill. It was under fluro's and after about 6 times they started to turn yellow, shrink and fall off. Starting from the bottom to the top. I think the spray built up on the leaves. Did not think about washing them with PH water spray. After I stopped the topps barely survived and came back nice.

When I got a problem like this I go back to bare basics to try and pinpoint the problem. Your ventilation sounds good.

hey bro, from looking at the color of those bottom leaves it looks like some
kind of deficiency which means there is probably some sort of nutrient lock
out going on.

also, Weedhound was suggesting you transplant into soil, even if it means going
to the store and buying a bag, because soil is much more forgiving than hydro.

then, once you get it stable, you can always take cuts off it and try hydro again.

hydro can be very tricky to get right if you are unfamiliar with the process and
very tricky to diagnose from just pictures.

what you might try is simply dumping your res and re-filling it with ph balanced
water and a couple tablespoons of H2O2 (hydrogen peroxide) but transplanting
into some dirt is the surest way to be sure your lone plant survives, and even
that might not do it.

LOC NAR makes an excellent point, plus, they are too young for that, at 2
and a half weeks i wouldn't spray with anything but water.

Your using tap water. Do you know the PPM's of the water. Maybe too high.

What kind and where did you get your rocks ?

To be on the safe side I would try what WeedHound says about soil trans plant. They are dieing anyway. Till you figure out what it is.

um, not sure y u got upset, i simply pinpointed the problem that i had no soil, and secondly said that it couldnt have been any of the nutes as i have had this problem b4 adding any of the nutes.
so im sorry u feel as if i was lashing at u, but i wasnt, i was simply being informative on the situation so i can get an update on thoughts/conclusion and nothing else.

mmmmm, actually now that u mention it, i did spray them more than i should have i think, tho i havent sprayed them for 2-3 days, the problem seems to be stable for now, the yellowing isnt progressing as far as i can see and if it is its doing it very slowly, still looks like shit tho.

u think i should spray/clean the leaves with ph adjusted water only...?

mmmm, problem is there is no soil around where i live, the only soil avail. is from a small local store and its very low quality shit, so not sure if thats a good idea, and on the other hand, if i was able to sort out soil some how, do i just dump it in with the rockwool cube? cuz that fucker aint going nowhere its all stuck to the roots, i doubt ill be able to arrange good soil till the next day or 2.
i dumped the solution and filled with water at 5.8ph {and since i dont have hydrogen peroxide} i used oxyplus and a drop or 2 of superthrive. so will see wt happens.

thx for the thoughts everyone :thumbsup:

tap water, at 0.54 Ms, and 7.7.7.8 ph.

if you read through my cloner thread you'll see how to deal with transplanting
from bare roots and rockwool into soil. it's not exactly like your situation but
close enough.

as to the soil you mention, it would be ok as long as you added some perlite
for drainage.

keep in mind that many people keep their mothers in soil and just flower in
hydro, with dirt, you can almost neglect them.

i ment like should i keep the rockwool cube nd put it into the soil too and cover it.? sorry for the nabish Q.

second of all, G'd-up on the bubble cloner thread man, im going to build the exact one, i tried cloning 3 times, b4 my last crops died and it didnt work, did it with root riot and clonex gel.
but fk that, ur one looks the dogs bolloxs. ;).

oh n just orderd white widow, wonderwoman and papaya from nirvana, so im gona do wt u guys recommended, and im gona get some soil n do them that way n keep them as mums, and recomendation on spacific nuts for soil?

as for wts there now im gona keep them in hydro, n if they die then fukem lol. :D.

thx alot man, apreciate it.

Widow can take 11 week to flower and I think wonderwoman is 8 weeks along with papaya. Mate the Papaya is the bomb. That is what I have 2 of my mates growing now and what I have had the past few years. Everytime I smoke it with someone new to it. I ask them did I spray enough PCP on it, LOL cause one toke too many and your in for a couch ride for sure. If you get a chance my bro likes the Hawaii x Skunk from nirvana it's a very good upside med.

lol, its good that i chose papaya then, lol i was border line with getting ak48 but then i sumthing drew me into it.. Possible cuz the end of the discription it said {effects some what narcotic or sumthin looool.}

i might just order some hawaii x skunk the next time then and let u know wt i think :D.

oh n btw that sog grow link u sent is the BOMB lol, i am so on doing that, at first i wanted to do this : Get a harvest every 2 weeks - Marijuana Growing.

im gona do it hopefully as soon as i get those bloody mumys up n runnin :D.

have u tired wonderwoman? or heard anythin about it, seems to be good but not too sure???

thx for all the help again,
peaceeeeeee.........

lol, high bro, that was me that posted that link to DrBud's thread.

oh, and btw, lol, that link you posted 'get a harvest every 2 weeks' is exactly
the same concept as the one i post for you to check out, the only real difference
is that it's set up to harvest every 2 weeks instead of every 1 week.

think of it this way, you have a strain that takes 8 weeks to flower out to harvest.
if you put one clone in every week, in 8 weeks you will begin to
harvest 1 per week, and if you put 1 in at the same time, you have a single
plant SOG after that. just continue putting one in while taking one out and
you have yourself a perpetual harvest, 1 plant per week.

now, once you understand the principles you can tailor it to any size and
cycle you, yourself want.

shit, you can put 1 plant in every day if you want, or 1 every 2 weeks, or
every month, whatever cycle best suits your particular needs.

ummm u highhhhh breee.

"lol, high bro, that was me that posted that link to DrBud's thread". ====>
"oh n btw that sog grow link u sent is the BOMB lol", i am so on doing that, at first i wanted to do this : Get a harvest every 2 weeks - Marijuana Growing.
lool u highh bre...:jointsmile:

the only real difference tho in the one i sent u was that, its hydro and not soil therfor the yeild is higher{lol}, and he is growing in like bigger pots (175mm top diam) , thats why i started off in hydro now, but im taking ur advice and im buying soil on thursday.
biobizz all mix??? good enuff :).

im gona keep mumys in soil, and then when they ready try n do the clones in hydro, but now that iv seen the one u sent me, i dont have to grow in big pots anymore now that iv seen its possible to actually grow them in lil bottles, it will make my life alot easier and not to mention that i would be saving so much space. {need to go bottle hunting tho }:D. lol

heres wt im thinking,
im still thinking harvest every 2 weeks for my main sog, cuz it should be a lil easier.

im still not sure of wt strain to do the main sog as?
papaya or wonderwoman {my heart has taken me to papaya from the start and after u said uv had it i think im leaning to that for now}.

the white widow and the strain that i dont pick will be grown in another small sog on the side in soil and done the exact way the link u sent me was done in.
both the main sog and small sog should be interesting to say the least..:jointsmile:

u doin any strains/ops now?

What I'm most curious about is why you'd foliar feed Trichoderma so much. It's not a nutrient and there's no reason to coat a plant in it 2-3 times a week.

When used foliarly Trichoderma "fights gray mold, powdery mildew, Pythium root rot, Rhizoctania solani, Fusarium, Sclerotium rolfsii, Sclerotinia homoeocarpa and other problems that ruin plant health and decrease yields" but unless you're also foliar spraying those nasty things on your plants you're not going to need more than one treatment every couple weeks.

I use Piranha from Advanced Nutrients for my Trichoderma needs (mostly in the reservoir though I have used it foliarly before. I wouldn't be surprised if the frequency of your spraying played a role in your problem. I doubt quality Trichoderma would cause problems themselves, but there is too much of a good thing...

I agreee. I grow hydroponic, and usaully I go 1/4 strength nutes for the first 1-2 weeks, then 1/2 strength from weeks 2-3. Slowly build up nute strength.
My first 2 grows, I used 100% stregth nutes (whatever it said on the bottle)
They looked very good at first then slowly all died off, I guess like what you are experiencing. Once i switched to 1/4 or 1/2 strength, I got great results.

Remember, when U see damage to the plants, it was probably an issue a while ago, it just takes the plant some time to show damage, then by that time, its usaully to late. General rule of thumb for me. As soon as i see something odd with my plants, I flush and drop nute strength. Almost always works for me. Hope this helps

I just can't believe this guy is using genetics instead of bagseed. Am I reading this thread correctly? Or is this a bagseed grow and somehow I didn't figure it out?

oxy-plus, is that hydrogen peroxide? stop using it if it is. stick with simple three part nutes and and cal-mag if not tap-water(which needs to be aged 1-2 days). do a few weeks and if growth comes back, which it's stressed so it may not grow for a few days, add one additional additive per week and track which are needed and helpful. just my prognosis for what it's worth.
