ANYONE PLEASE HELP!!!

[toker4life]

ok,

so I followed the growing procedure here from the front page on cannabis.com. I started my plants off in a peat pellet solution and it grew terrific. Then I transfered it into a hydroponic medium. I have my plant under a 400W HPS (my MH bnulb busted). I am using distilled H2O. I am using GH line of nutes. 3 gallon bucket with airstone on bottom and water ring on top.

The problem is that my plant is now stunted in growth. It also seems that the top leaves are drooping and turning yellow. WHENEVER I so much as even add the SMALLEST amount of nute solution (I've enven just done 1/8 teaspoon TOTAL of each nute per 3 gallons) to my hydro solution it shows signs of burn. The leaves curl up and things get ugly.

My plant is about 5 inches tall. Nirvana White Widow.

What am I doing wrong? I can't loose this one.

[LOC NAR1958]

White Widow is a pretty hardy strain it clones well. 5 inches should be able to take light nutes. Strange. You can veg under a HPS but get another MH when you can. Light not too close ? The big question is your medium and did you gently wash off all the peat pot ? If the peat was not washed off it will be all in your system, cloged lines and worse. TOO wet at the rootball, I think damping off it's called. The roots that hang down can stay in water all the time but not the rootball it like air. One more thing, Do you have calmag+ to add back to the water. That can be a lack of magnesium. Cause nute lockout. And how's your PH, it can cause problems and lockout too ? Pictures help, if you can you will get much more help. A pic is worth a thousand words.

I had the same problem when temps were too high.. plants were trying to soak up water to beat the heat and nutes were killing them.. even at 1/4 strength. I brought the rig into the A/C and they have done fine ever since, infact they just went to full strength nutes 3 days ago with no signs of stress!! how are your temps?

[LOC NAR1958]

Good call I forgot about temps.

[toker4life]

well its been under the same exact temsp for a long time. it was litteraly a matter of 1 hour and the leaves curled. It hadn't curled before. Just when I addded the nutes. its freaking weird.

Yes I washed out all the peat. There is no more brown water or anything coming off it. Its completely clean.

Should I just go to 12/12? its about 6 inches now.

I have a fan blowing across the plant and the light. its not that hot in there. Its hotter outside!

[Aaron385]

how hot at the plants exactly? > 95F?

[toker4life]

less. prolly 85

[Aaron385]

if its hot the plants can keep up with water alone but they take up water at such a rate that when you add the slightest amt of nutes you get that curl up real bad.. I had to move plants inside and dial down my centeral A/C to keep temps below 80F.. then and only then did they start responding with just a little curl up @ 1/6 strength nutes.. a week later I went 1/2.. same response.. but leaves got better in a couple days.. a week later I went full strenth and I havent seen any signs of added stress yet.. although just when I thought I was the hydroponic master I was folar wattering today and noticed creepy crawlies all over the leaves.. not sure what they are yet but fuckin hell.. can I get a break already? jeez

get a thermometer and find out exactly.. that temp is too close to guess.. since it could be whats causing a problem

oh and humidity.. if its super dry.. bad.. thats the other thing that turned mine around.. a cheap ass humidifier to keep the air moist.. that means less water used by the plant

[toker4life]

ok, well I have a closet setup. isn't the humidifier going to cause mold in there and water damage?

won't the fan just blow away the mist?

[toker4life]

this is a closet setup. about a 2x2 area

[toker4life]

SHIT!!

Its 100 degrees!!!!

goddamn.

what do I do?

will the humidifier lower the temp? do I need a second fan?

[LOC NAR1958]

More vents or AC. You want good humidity when you veg and lower (below 40%) When you flower.

[Opie Yutts]

You don't really need an AC, but of course it would help. Just vent stuff more efficiently and/or with more CFM. You really need some way to remove and replace the air in your grow area.

[Aaron385]

yep... with 400W HPS in a 2 by 2 closet you NEED to get temps down.. also it is very likely that the light is drying the air out.. like badly.. so I think at a bare minimum you need a good intake and exaust system (not just moving air around inside) and consider the humidifier option.. heat transfer does happen better when the air is wetter.. thats why on a hot humid day it feels much hotter, or on a cold humid had it feels much colder.

You could set up the intake and exaust with two $5 fans.. it doesnt have to be expensive but you do need to get temps down.

[toker4life]

well what temp should it be at ideally? I moved my fan so its blowing only on the hot lamp. the temp lowered into the mid 90s.

Where does the temp need to be at?

should I go to 12/12 now that its 6 inches tall?

[toker4life]

won't the humidifier mildew up my closet?

[toker4life]

ok, so I got one thermometer from outside and it says 95 degrees.
I got a thermometere from my reptile cage and it says 75 degrees.

My house is currently 80 degrees. There isn't much of a true change in feel from the closet to my house. So I am thinking 85 degress. lol.

is this a good temp?

[Aaron385]

I cant answer the 12/12 question because I dont know. I wont tell you anything im not sure of from my own expeierence.. Im sure you can appreciate that.

As for the temp.. 90 is better.. but this is (contrary to what some believe) not an exact science. I would go ahead and try nutes again if you can keep the temps down but watch closely because you are still right at the limit (95F according to most).

Ideally - 78F but if you are like me that is a pipe dream.. my A/C for my house isnt even that cool.. if it was good god my electric bill.. anywho.. my room stays between 80-85 in the day and about 75-79 at night.. I am in a super hot climate so right now thats the best I can do.. but I keep my eye out for "Window unit for sale" adds and I will be getting one before I switch from flouros to the 1000 watt HPS that came in 2 days ago :)

To answer the humidity question.. I will caution you that I dont have the years of expierence that others here might and my grow area is enclosed inside a closet with the humidifier inside it.. but most likely I would guess that you are in a hot climate running the A/C constantly more or less which dehumidifies the house. I would def cover the walls at least or put a fresh coat of paint on them.. I would venture to say that one crop cycle wouldnt do damage and at least if you were to just use it for a bit.. well hell.. first go get a $5 hygrometer and figure out where your humidity is at.. this may be a null and void point if your humidity is already high.. but if you run the A/C most of the time it will probably be low.

Im lucky because I rent.. so I dont care about mold :)

[Aaron385]

Its hard to say.. with the closet shut the temps could be rising you know.. I use a $15 rig I picked up at home depot, its the wireless indoor outdoor thermometer, i just put the outdoor part in the grow room and the indoor part on my desk.. little does anyone know when they see me sitting at my desk looking at my indoor outdoor thermo that i am watching my grow room temp :)

Plus I get to see what the temps do when I am not standing there with the door open.. and as easily as glancing a few inches to the left of my computer screen I can tell you that the temp is currently 81.9F in my grow room :)

[Garden Knowm]

love

You do not need to add humidity to hydro/aeroponic systems... you should not add moisture to the air!

the water plus the heat from the lights should always produce more than enough humidity..

and NOW you KNOWM

[toker4life]

I have a humidifier but I really dont want mold or wildew growing in my home. .

does anyone know how long it should take for the plant to recover. it seems to be stabilizing much better.

[Aaron385]

stabilizing with or without nutes?

[toker4life]

ok. I have a 3 gallon bucket.

I put 2 1/2 gallons distilled in there with 3/4 teaspoon TOTAL of Micro, Grow, Bloom each since I wanted to avoid the burn problem again.

They don't seem to be curling or anything. However the top leaves are more yellow than green.

How long should it be before I see growth again?
What could be causing this yellowish color?

Is there a guide online about different kinds of plant deficiencies?

[Aaron385]

heck yea there is..

http://www.geocities.com/nutrientproblems/

My method on nutes was to add untill signs of stress with a enough room in my res to add plain water to dilute once stress was noticed (about 1/6 strength).. then run that mix for a week and swap out for 1/2 strength, run that for a week, then go full.. didnt have any issues with that.. noticed a little leaf curl up when I went half and full but it cleared up within a couple days and it was obviously not bad, just a noticable reaction. Now plants are super happy at 1000ppm.

oh and check your humidity with a hygrometer.. some climates it would be very accurate about not needing a humidifier but if you live in a dry hot climate the centeral a/c in your house will lower humidity to the point it will stress the plants.. I was getting 25% humidity in the grow box without a humidifier and the humidifier uses one gallon of water a day just to maintain 50% in a 2x4x4 cabinet.

[Opie Yutts]

Sometimes a plant shows stress when there is a combination off too much heat and too much nutes. Reduce either one of the two and the problem sometimes goes away.

A good grow room temp is about 85F. I've read about plants doing just fine in grow rooms that were 105. Different strains do differently in this area.

I wouldn't even consider a closet set up without air exchange, unless maybe I was using a couple of weak flouros.

[Aaron385]

CO2 can help allow a higher temp band too.. might look at one of the el-cheapo co2 solutions.

[toker4life]

I will definately do that.

I am working on the solution now.

I am going to try a couple of things to see what's up.

[toker4life]

ok. humidity is at 55%.

Temp is remaining stable at around 85.

Plant still not showing signs of progress. What now?

How long does it take for a plant to recover from nute burn shock?

[Aaron385]

im sure others have opinions about this.. Im sure the only right answer is the one you will have in a couple weeks.. but for me it was 1 week with almost nothing going on (better than the burning look) and then I upped nutes to half strenght.. about one more week with very little top growth.. roots were growing tho.. then full strength after two weeks and they are now goin to town.

good humidity too.. dont need the humidifier.. temps should be fine too but you might want to add co2 with that HPS light.. that would make your temps ideal.

[Bachelorpads]

well, i think you are fighting the wrong thing here. What is the temp of the water in the bucket? It should be 75 or less. 68 is usually optimal but that is all a preference thing. Use frozen pop bottles or ice or whatever you can to chill the water. That is what i think is the problem. If the water is 70 and the room is 95 (which will suck because you will go through a lot of ice making) then everything will grow fine.

My best guess.
