Can't seem to get it right

[chuck1221]

does anyone know what is causing the edges of the leaves to curl up almost roll up but stay dark green or no color change at all. I tried lowering the nutes, rasing the light (600w MH), ph 5.8 and it stays 75 degrees at all time.
It' in a areoponitics set-up
If anyone has the answer I'm all ears
Thanks

You might try giving them a less intense light for awhile. Just my opinion and what I would try, don't know if I am right. Would like to hear what others say as well.
