Help my one week baby

alright so after one week my babys were growing great! but one day i woke up and it was curled up? i water it every day, but i just go by if the soil was dry or wet. The two bottom round leaves that first popped up eventually turned yellow but i heard theyll do that after the plant uses up all the nutes from it. I was wondering if any one knows whats going on with them?! helpp mee

and the worst news i had two going but i got ride of the other one because it fell over and dried up.

well its hard to tell with out pics.... but it could be because of heat stress... if the plant is undergoing heat stress the leaves will curl and turn up usually.

dude, post pics. how the F are we supposed to help you just by reading what the plant is doing.

alright there's a pic. i shoulda posted it earlier my bad

your first round leaves shouldnt turn yellow untill the plant is established. 4 or 5 sets of leaves. or right around 2 and a half weeks of growth.

your most likely overwatering for 1, cannabis NEEDS wet dry cycles for strong healthy roots. Did you try feeding them? how hot are your temps? what kind of soil is that? what is your ph at?

its fox farm organic ocean forset soil, my temps usually are about 85-90*F during the day and 75-85*F at night, i feed them once with fox farm Big bloom. no ph unknown no test done. under a 400w HPS light

how far is the light from the plants?

about 21 inches

im pretty sure its overwatering. The top may look dry but that doesnt mean the whole thing is. You should get a ph tester asap....its important. I wouldnt start feeding this early, even if it is only w/big bloom. I'd wait till week 2 or 3 to start it. Do you have a fan in with them to strengthen the stems? Imo its alot easier and works better to use cfls the first 3-7 days(keeping them as close as possible to the plant) then put under the hps.

I have a fan below blowing air up, just with a little breexy, i should get a fan and point it dirrectly at them. So should i just keep them under the light and not water it till its dry? and i also started them out in a rockwool starter cube if thats any useful info.

yep, just get a container the same size as your growing in, fill it with soil, the same type your using and with any pearlite or other mix ins the same.dont pack it too tightly, but dont leave it really loose either. now the next time your wondering if its time to water go and pick up that container, then go pick up your plants container. You will be able to tell if its time or not. after a few times you wont even need the container of dry soil anymore.

what hours should i be running the lights on?

cool man! thanks for your knowledge

i'd go 24/0 for the first few weeks, helps jump start them, and then move to 20/4 or 18/6, having the 6 hours be during the hottest part of the day. They will start stretching at *night* , I let it go till about 1 ft-12 nodes or so and then top and begin low stress training so all those growth points become main growth points that are all reaching for the light. .

make sure you get plenty of humidity for the bad girl there... also, i'd recommend switching to CFL's for the first 3 weeks of life.. just my opinion.

for the humidity, should i just be placing bowls of water in the closet?
ive had the lights on 24hrs but i wasnt sure if i should have em on all day or imitate a sunny day and turn it off for night.

First of all, make her a little humidity "dome". If you can find a 2 liter cola bottle or something like that, cut from the bottom about 4 inches and place over the plant.
First couple of weeks I'd say keep the lights on 20/4 to take it easy on the seedling. When it matures a little you can go up to 24/0 or stay at 20/4. That's just my opinion.

85-90 a little high u dont need big bloom use a fertilizer with 7-9-5 or 5-10-5 or 4-5-3 for veg cycle

Aim for 70 F. Anything higher than 75F will be too hot and will damage growth. Make sure the water for watering is luke-warm.
