growing question

[pfunk211]

did you transplant recently?

the one on the left looks like it's been choked out in a container that was too small for it....

looks deficient but improving.....

and the edge burn on the other leaves, do you let your tap water set out for a while before you change your res??

chlorine will burn your leaves and is abundant in fresh tap water

humidity when the T5 is on is about 80 pct for 18 hours a day apprx....could the high humidity be a problem ?

oh i see, i thought it was six to seven days. you are stunted and your humidity is way too high. its probably higher with lights off. add a fan and sounds like you need an exhaust system and fresh air intake. yellowing i dont think is the issue, your lacking growth so uptake in the roots is lacking which is causing the yellowing. see how advanced your roots are if possible. get rid of tap water if feasible, adds to your ppm which allows less to be absorbed by the root system. like junk food for bud. your feeding 6x a day maybe cut back one and see if that helps. we still need info on how much your feeding nute wise. the fact you have not had to adjust ph suggests also there is not much uptake so try a leaching solution to minimize salt build up (clearex is one i know of.) high humidity can cause lack of respiration aka slow growth so definately start with that, lower ph and heat just a tad, and get a leaching solution. dont worry your salvageable.

Thanks for all of the input. I made a few changes. This input is for the plant on the left, I have lost a couple of the bottom leaves and a few others are starting to turn yellow. I vented the room and my humidity is now at 50%, inside temp 78 and ph 5.55. I am using 80% technaflora nutrients, which consists of (15 gal resv) Boost 120 ml, Grow 60 ml, Thrive alive red 20 ml, Magical 20ml and Sugar Daddy 80 ml. I let my tap water sit for 2 days and added the new nutrients this morn.

Even though your PH and humidity arent ideal I dont think that is the problem. Your pics arent clear but it looks to me like a deficiency, possibly calcium or magnesium. You say they've been in a flood table for 6 days but are 8 weeks old? Did you just get them?

the plant was a clone received in a plastic cup in rock wool in medium. I had it in the cup for approx 1 1/2 wks and transplanted it in hydroton. I was told that it was ready to be transplanted, so it's approx 3 - 4 wks old maybe 5. Here is a better look today, new nutrients today, I have already lost 2 leaves.

new growth looks fine. is it just an inch or two from the T5? it should be..

I dont think you have much to worry about, except it looks wet. I assume they aren't going under when you are flooding? I would just trim those lowers off.

it looks like its coming around, stick with your new method you should be alright . sometimes it helps to document things if your not already. good luck:thumbsup:
