is this neut burn? im using 400watt mh. light is about 13'' away from the plant, i transplant it into hydro on 3-08 so its about 3days alrdy. i saw the yellowing a day or 2 after it was in hydro. and i gave them half teaspoon of neut in about 9gal of water. i have 6 plant in the system. 2 of them is about 2weeks old and the rest are same age with the yellowing one. so im thinking if its neut burn then all the other young plant should have burn too right? if it is neut burn, can i drain half the water and refill it with plain water? or do i need to replace the water completely? thanks for the help. if it die i'm gonna replace it with tomato! i attached 2 pic, the 1st is 3-08 at 2am. and 2nd is 3-11 at 5am.

Thats what it looks like to me. I would swap out 1/2 the water with plain water and readjust the PH and see if that helps in over the next few days

Also, 13" with a 400W MH is too close for those little plants. Back it off to about 18-24 inches and see how it goes.

Yeah i think it's more of a heat issue and a pH fluctuation.... Just what I see though. Be sure to keep an eye on your pH...I don't let it fluctuate more than .2...

thanks alot guys, i will swap out half the water and move the light up. i'll have updates.

ok so i swap out half the water with plain water. i kinda changed my setup so i can fit a small humidifier and a box fan, i will relocate the box fan or do something else to it later when plants get in the way. i changed the light and reservoir from horizontal to vertical. With the humidifier, the rh raised from 20 to about 55. i included an update pic of the leaf yellowing plant. the yellowing went from the vine to tip of the leaves. i noticed the plant grew quite a bit in 2 days. plant 2 is the one with the yellowing. Plant 5 stay looking the same, i don't think it grew at all but roots growing in water. i was paranoid after transplanting my babies into dwc. couple of the plants barely have root growing out of rockwool but i transplant anyway. its been 3 days since they been in DWC and all of the plant's root growing in the water. (i know, i know patience.......) sorry i cant find the quote but hey my pH been more stable and i do see rapid grow! thanks for everyone's help, i needed it. please help if something is not right.

hello everyone, i just notice my 2 oldest plant have some leaves browning. i dont know if its something i should worry about or just relax, but i noticed it last night and i checked this morning its even browner. my plants are about a month old. well, see what had happen was, i was adjusting my lights and i heard my hook feel off, so i look and look for it and i couldnt find it, so i gave up. well 10 days later when i changed the neut i found it in my resorvior and it look kinda brownish rustish color. so that mite b it? haha i bet no one ever had that happen b4. anyway so while i switch the resorvoir tote i kinda touch one of my plants wit something (mayb reflector). so i see the new leaf folding down a bit then i checked it about an hour later, it wasn't folded down anymore. so i was happy but i check this morning like 7 hours later and they look kinda folding down again, the leaves look dark green now, o i gave it 1/2 teaspoon neut (mayb this is too soon for 1/2 tsp?) i was giving them 2/3 tsp then i had to change out half the water with plain water. so mayb it is too soon for 1/2 tsp. anyway talk to yall later and ill keep updating.

ok here a little updated pics. i pruned alot of leaves and did a little LST, they are at 24 days now, and i also gave it 2-3-2 FloraSerie nute. they havn't showed any sign of neut burn yet. i had to top off the water cuz its so hot in the attic. i added another 5ml each. its been 2days with the new nute. hopefully i wont see any nute burn tonite. should i do some more pruning?

 

[TruTHC]

should i add nute when i top off my res?

 

[AlienBait]

Looks like your plants made a very nice comeback! Looking good.

Since your space is so small, you may want to start flowering soon.

When you top off the res, just add ph-corrected water. Be sure to check the PH after you add water as well.

By the way, I read in your other thread that you want to throw in a tomato plant. Be careful, those hydro tomato plants can get huge!

 

[TruTHC]

hey AB, nice to see you here and thank youvery much for ur helping info. o yea i think i'll just try to hurry and finish this crop then really grow tomatoes. and hmm never thought about flowering soon, that makes sense. its been 23 days for them so far. but i just did alot of LST so all the leaves get better lights and i added 1/2tsp superthrive and 1tsp epsom salt for the first time i have 8gal of water. i hope thats not too much ST hope my plant aint gonna be fried by tomorrow. i wasn't sure if the epsom was necessary cuz u see no sign of anything but i read some ppl do use it so i thought i'd try it. anyway i just pruned like 40+ leaves in the last 2 days but i got a recent pic taken right after adding ST and LST. let see how this work for these babies

 

[TruTHC]

i got kinda carried away starting other thread and asking questions and kinda did a grow journal there, haha. now im back to this one update some pics. the first pic is 4 days after the pruning was done, it seem like it was more than 4days of recovery. the second is 6days after prune, after they recovered they started growing really fast again.

 

[TruTHC]

i started flowering on 4-10 and gave them 4week amount from the GH website. i switched out some nute i got from homedepot to GH FloraSeries. i'm liking it. the plant is drinking lots of water,about 1/4 a day (8gal res.), so i really have to keep an eye on it and top off everyday. i think im getting some nute burn, only on a couple of plant, i hav'nt adding nute when i top off, i topped off about 1/4 with plain water about 12hr ago and i didnt notice anything different about the plant, but im sure i'll have to top off tomorrow that will probably make it better. the burn on the leaf gonna stay burnt right? except for the new growth?

 

[TruTHC]

the new growth on a couple of the plants look very light green/yellowish color, and the center of the new growth's small leaves have a purpleish color to it. i dont know if its normal or some kind of bad sign, can someone please tell me whats going on, i took the pic under hps so its really hard to see the green, but i hope u can see itin the first pic, the redish leaves are not really red, i think its just the flash and hps that make it look like that. the light was about 9inch away i just raised it about 3 inch. ph at 5.6 and ppm was 1300 then i top off now ppm at 895, thats prolly will do alot better for them

 

[TruTHC]

haha look at my only soil plant, i gave it 40watt cfl (2600 lumen) and it was too close so it really burn the plant so i gave it some superthrive hopefully that will help.

I don't see nute burn anywhere man. I do see a lot of different things though. Like and N def. and overdose... :huh: I would have my ppms around 1100 or so with the plants that size, but, I don't use your brand of nutes either. How long did you run it at 1300 ppm?

i gave them 1300ppm for 2days. i topped off now ppm is at 895. im using GH flora serie, i think the "grow" have more N in it, so should i give them more N? yea i think i kinda ODed them.

 

[AlienBait]

I dont' see any nute burn either. The light green on the new growth is a good sign. It will darken up in a day or so.

I don't know about the purple......that usually means potasium def.

Some of the leaves are curling up on the edges, that usually means Mg def. Dissolve a tbl spoon of Epson Salts into your water the next time you top off and that will be taken care of.

Your PH is good.

How close are your lights?​
