Leaves Curling Up

[xXMrDenverXx]

I have had some issues.I have 3 plants and some of their leaves are curling up. Like they are reaching for the lights. No nutes yet. About 10 inches tall.

You are supposed to give nutrients even in first week,1/4 str/then 1/2 and then full and then go up,second add pics,third if they still little plants but long stems then put light closer,way closer than now,if they are bushy 10 inches trees then give nutes..

need more info.... dirt/hydro?? temps?? ph?? how often are you watering?? how close to the lights?? is it just the tips curling up or the whole leaf?? are you able to post pictures??

Pics would help. Curling might be from heat, that's the most common cause from what I know. Don't use nutes until 2-3 sets of leaves appear, just use distilled water til then. Since your plant is 10 inches I'm assuming it has leaves so nutes might be fine. Really not sure though without pictures

How are they exactly curling up? In a natural or unhealthy way?
