here are a few pics i got today there are a few small yellow spots on the tips and the lights are pretty far i think i mean they're CFL's. Could it be a K or P difficency since i'm in the flowering stage?

here are a few pics i got today there are a few small yellow spots on the tips and the lights are pretty far i think i mean they're CFL's. Could it be a K or P difficency since i'm in the flowering stage?
here's a few more...
downsize your pix...I waited almost 3 minutes to get 1/2 your pik...gave up. From what I "can" see, It looks like you spilt nutes on them. I thought iIsaw a spider mite problem, but cannot get good enough look at them due to size of pix...I usually resize to 2mb and it fills the page here; And quickly...Will check later to see if you downsized a couple...give us a downsized shot like pik 4 in 1st post.
The stalk's purpling. It looks like phosphorous deficiency.
That last picture of the fanleaf looks sort of like a potassium deficiency in the making. I don't know what kind of medium you're using, or what fertilizers you may or may not have given, or if you tested the pH of the soil and/or runoff.
Could you elaborate?
Latewood; I can see purpling at the top in the second picture from his second post, and it extends all the way to just about an inch or two above the soil. It's in patches up the stalk.
Could that be a phosphorous deficiency due to underfeeding, or perhaps pH imbalance related lock-out?
Downsized picture below.
yeah i thought it could be a diffeciency but wasn't sure and what i could put in to help it,right now i give it worm castings and water that i let sit out for a day or 2, LATEWOOD i think that what you're seeing on the bottom right leaf is somethign from what it was growing, it's alike a shiny type of substance looks as if it were sprayed with sugar in that spot and dried but this is not what happened, idk what it is.
this help latewood/anybody?
It is a magnesium deficiency. Mg def. is caused by:Quote:

Too low a PH causes an excess of nitrogen, potassium, and calcium to be available to plant and locks out magnesium.
adjust PH
cut back on EC/ppm's to allow water to evaporate at a higher rate and allows the availability of Magnesium.
treatment:
a. 2tsp epsom salts per gallon. until leaves regain good color...starting from the top down.
b. keep rootzone at least 70 degrees
Question's:
1.what ph is your soil...with mg def., one should run ph above 6.5
2. what nutes? at what mixture? are you using.
3. What type of soil?
4. how old is plant and what photoperiod are you in?
i'm in my 12/12 cycle right now started on this past saturday,
right now i add nothign to the soil except liquified worm poo for nirtogen once a week because the soil had slow release ferts which i knwo isn't the best but didn't knwo that really till after i transfered them,
i'm not sure how to test the soil's pH only way i know is with a pH meter or strips for liquid,
All of the plants are about let me see i germinated then on March 11 and planted them a day or two after so i'll say a little over a month!?!?!?
The soil was a bag i bought at HD it was the least amoutn of ferts added from what i read on the bag but it's not MG
I have 3 42W=150W CFLs on them now. Do you think that i need to add some (K) and (P) also
Thanks for your help so far

Can anyone comment on the new pics any further?
measure the EC of your soil. I think you have a slight acidity problem. nothing to worry about at the time, but you might want too look in too it.
I'm guessing you have a PH of the soil of 5.5
so how can i adjust that and how to i measure the EC of the soil? so you think the leaves can be yellowing on the tip or smething from Mg like LATEWOOD said?
I don't thinkif it's a magnesium problem, I think It's a more common problem. Put some soil in a glass and add some PH 7.0 water untill you get thin mud, let it sit there for an hour. Then measure you acidity (PH) of the mixture and you'll know the PH of your soil. It should be between 5.8 and 6.2
if it is a magnesium prob ya can sort it with epsom salts
just half a teaspoon to 1ltr of water and water them with that
epsom salts can be purchased from ya local chemist
lol they are also good for constipation lol
cheers all :)
ha ha yeah but do i need a pH solution to test it i mean you can't use a test strip cause it's be all muddy
i use the draper soil tester for ph testing
it has 3 settings to test for
ph balance
moisture
and light
you just poke it in the soil wait for a minute and read the result on the little screen
cheers all :)
how much does this little gadget go for and can you get it in a regular garden store?
i got mine from a place called wilkinsons in the garden section
it cost me about £6 UK money
cheers all :)
I test the ph of soil by measuring the runoff...water your plant...measure the runoff with a ph meter...
I also do not agree with britewire about your ph...the bible and every other reference to growing insoil states to keep your soil at 6.5...
I am not trying to piss in anyone's cornflakes, but I think that is bad advice...Sorry
Britewire and I have debated about this in the past, but I think the majority of experience growers anywhere, will tell you emphatically, to use a ph of 6.5
5.8-6.0 for hydro, even down to 5.4
But if you follow britewire's advice and 'I' am right, then you fry your plants; Because low ph is more acidic and I think that is the root of your problem...that can create a mg deficiency...
another thing is My way you save your plants with no adverse effects...
follow britewire's ph advice and you might be OK???
One thing for sure is No-one other than britewire that I know of set their PH to 5.8 in soil...No-one.
Too many chiefs here now...good luck, and let me know if you need anymore help.
By the way; the advice I gave you pretty much comes right out of Jorge's "The Indoor bible"...there is not a better more up to date source for Indoor horticulture than this book. lw
to fix your problem, I think you should leach your soil...
go online and buy some good organic Bloom nutes like Pure blend pro, and an inexpensive ph meter...that will get you in the ballpark. lw
thanks again guys, that's what is good in a place like this i mean everyone has different thoughts, i will 1st try out the Mg defficiency then if that doesn't work then i'll look in to the pH probably.
Again thaks everyone for the advice

OK, this got all confused...Quote:

The MG deficiency (if that is what the problem in the leaves.) is caused by TOO WET/TOO ACIDIC (which means,
PH is TOO LOW)
this is a cut/copy/paste of what I posted above...
a]. Too wet/cold of soil,
b]. Too acidic/cold of soil...
c]. Too Low a PH causes an excess of nitrogen, potassium, and calcium to be available to plant and locks out magnesium.
adjust PH
cut back on EC/ppm's (which means, cut back on nutes...leaching is a good alternative, precautionary adjustment)to allow water to evaporate at a higher rate and allows the availability of Magnesium...end of paste...
so you must address the PH problem 1st...buy a ph pen.
measure ph of water run-off, to determine ph.
by leaching* you remove all the salts that could cause a lock-up...
*leaching: with water(you can place them in the shower), or, pour 3 times the capacity of container through pot and drain off, use oscillating fan to help dry up the wet soil...
when soil dries almost completely...Add a fresh batch of 'Pro Nutes' for soil or soil/hydro...
I recommend. Pure blend pro, because it works great, it is organic...And I don't think you wil find One hydro store operator that will Bad Mouth it. they all tell me It is tried and true. I use it on all my vegetables...I use AN/GH
3-part for 'our' plant.
Pure blend Pro organic nutes will take alot of the guess work out of your growing...It is safe, I have used it for about 8 months, I veg my MUMs with the PBP VEG formula for hydro*
*make sure you get PBP for Soil/Bloom Formula...
You hardly use and VEg formula, but If you can afford the luxury your next grow...Buy the VEg, also!
I hope this helps. Remember I agree with britewire on the fact that PH must be addressed, I just don't agree with his PH level, suggestions... that's All...I gotta go tend to the Garden...
go get some limestone or calcium for your soil. do it do it.
I think Latewood has it covered. If you use tap water it probably isn't a Mg. deficiency because there is plenty in tap water. More likely the Mag is locked out do to Ph problem. You can buy a ph tester like that one in the pic for under 10 bucks and it will save your grow. You are going to need Ph down and up also.
well i use tap water but i let it sit out for a few days 1st, i put in a 1/4 tsp of epsom salt in a pint of water and will see what happenes, if in a day or 2 i don't see any change then i will fluch the roots with water andd start fresh
Thanks guys
