Looks overwatered. Can you give me some background on your grow? I might be able to figure it out pretty quickly.

What type of system? Ebb & Flow, DWC, etc?

What is your watering schedule?

What kind of nutrients are you using?

How high is your ppm?

What is your current ph?

What type of lights?

And can you please take a pic with the lights off?

What is your watering schedule? wait til perlite is damp to dry. then water (see below) until about 1cm layer on bottom. about 2-3 days

What kind of nutrients are you using? GH micro and grow

How high is your ppm? 370-400ppm

What is your current ph? 6.5-6.8

What type of lights? 600w HPS approx 3.5ft above plants. temps about 74-79F

And can you please take a pic with the lights off? done.

thanks a million.

Stop grow nutrients. Check your Ph meter - it could be low Ph. Grow nutrients + low Ph = nitrogen burn leaves. I think thats the problem and curling down leaves becouse of too much water.

ill give it a shot and a flush. the only reason i started adding the nutes was the cotyledons started yellowing right after the 1st leaves came out. thanks :)
