leaves curling up length ways im a first time grower

[fili209]

hey guys i have 3 of my 6 plants that have their leaves curling up length wise

i have a 600 watt hps light
roughly about 2 or more feet off the plants

i have them in 5 gallon buckets

with fox farm soil

i havent added any nutrients
to them cause they have only been in the soil for about 2 weeks

and people told me that this soil is hot for about 3 weeks so im waiting

can someone help me?

Pics are a little blurry. Looks to me like either heat stress, lack of water or a combination of both. Have you temp'ed the air just above the tip of your tallest plant? I'm betting it's in the upper 80's to mid 90's which is too high. And your soil does look dry as well, but again, hard to tell in those pics.

what else could it be

Shouldn't be anything else at this stage of growth. If the taco-ing effect is mainly on the upper portion or new growth of your plants, the lights are too close. If it's on older leaves, your temp must be too high.

Are you running 24/0? If so, maybe consider switching to 18/6. But that's just my opinion.

Good luck.

my lower older leaves are curling so im thinking tis too hot
so i raised my lights up about 6 inches
and i am running 18/6
cause every living thing needs to sleep

Heat stress. Get some fans in there!

i agree with most of the posts -- heat issues or lights too close. once you get the thermometer, you'll have your answer

circulation would help with both problems in the mean time...

ok well i have 1 fan circulating air
and 8'' inline fan sucking out through my ceiling into the attic

and ya
just waiting for the thermostat

how does air enter...what is that a grow tent? is the inline fan pulling air directly from the grow room, or from the room the tent is in?

is there glass sealing your light?

 

[Spoony Da Dro Man]

how are his lights too close if they are 2 or more feet away? aint that too far?

 

[scoregreen]

600 watt hps tho...i keep mine 12 inches with 400 watt -- a buddy of mine does 48-54 with his 1000...

I fed my plants molasses and the leaves did that.

 

[fili209]

ya there is glass covering the light is that bad???

and idk if they are too close how far are
600w hps supposed to be?

 

[scoregreen]

nonono, glass covering it is good -- the idea behind that is that the air intake, which should be right above the bulb, or elsewhere on the fixture will provide air in and the inline fan sucks the heat out -- which should allow you to put your light a little closer. hold your hand as close as you can to the light without it burning, the distance should be the same between the bud and light.
