This is a 3 week old weed plant in a 2.5 gallon pot
I water it when the soil feels dry with a ph of 6.3-6.5 I just started feeding it
My humidity stays around 40 to 50 %
I'm using 8 23 watt 5000k can lights

Although my temp is under 70 degree f could that be the problem

By watering when feels dry do u mean feels dry to the touch or u pick the actual pot up and its very light...go by pot weight

Also 23w CFLs won't cut it for long...ull get much better results wit a 8u 250w cfl but I'd recommend a hps/my system if u really want to have something that u won't want to upgrade

I "think" you might do better with a dual 32-34 watt per tube, 4' daylight florescent tubes.

Maybe spend $5 on a hygrometer so you have some idea on watering.

That plant is too little for a whole lotta nutrients.

Ur plant is to young for nutes like he said ...and with that high of a npk value I'd go quarter dose but only after a couple weeks.... The other guys right ur in a huge pot for ur plant size and that causes over watering .... However u do not want to water around the edges every other day ....wait until the pot gets really light when u pick it up...u want the roots to chase the water all the way to the bottom......a little superthrive or root accelor lator would help very low doses......

That's a really long light for one plant...although it is cheaper if u already have the fixture...if u can open grow in other words not in a tent or box...like if u can use a spare room or basement id I'd suggest a 250 watt HP's on 20/4 or or 24/0 the HP's puts out high temps and venting can be expensive...hardly worth it for a 250w and one plant....now a 4x4 grow area with a 1000w mh/HPs ...9 plants 7 weeks veg under 24/0 is what I'm running nice gpw ratio and dense firm nuggs.

You want me to water around the the edges until I see run off,or just a couple tablespoons

3 weeks old and the plant is 2 inches tall???????? Start over with a new seed, don't fertilize for 10-14 days.

You're not using fertilizer that's proper for growing marijuana- you need to buy a complete hyroponic fertilizer with lower N-P-K ratios and 1 for veg and another for bloom.

pH seems right......

IMG3548.jpg Zaz your small growth can be from a number of issues from improper light source to out of wack soil problem with diagnosing issues is were not there or no the strain and your environment,, Curling leafs can be a number of things from and can be a very inherited gene trait
Now what you need to do cause for 3 weeks there is obviously something wrong ,,
Temps lights soil ,, ph etc
My guess is a imbalance in soil causing plant to do nothing or your Light source is 2 week

My suggestions is this go and purchase 1 bag of EWC Earth worm casting and one bag of perlite as well one bag of top soil .
Put half bag of top soil in a pail and then open bag of perlite use a strainer and rinse perite so all dust is removed once that is done put all perlite into top soil and mix then open bag of EWC casting and put half of that into the top soil mix well then i would carefully transplant that seedling into a new pot and new mixture , i would then some how collect rain water and use that to water your seedling Cheers 4th week seedling and 2 feet tall started under t5 and out side in sun now 3 weeks 4 weeks old rain water only and that mixture with EWC and grass clippings as mulch
