I just start noticing this yellowing on my top most umbella leaves. And one or two are curling down. Its only on the top leaves really too. I am using soil. I water 2 times a week, 1 quart per plant each time i water. I just put them on 12/12 3 days ago with a 400 HPS. I had it only a 1 and 1/2 feet away first day with no fan. I have since raised it to 2 feet 3 inches and added a fan. This is one thing i think it might be( i burned them a little.) Or I was thinking mabey a oxygen problem because i didnt add any sand or perlite to the potting soil other then what came in it which looked like a fair amount. Any oppinons?

This is the worst of the leaves too.
you should be able to keep your 400 watt hps about 16 inches from your plants pretty easily. do you have a fan moving air around under your light?

P.S. those leaves do not look like they got burned to me.

looks like a nute deficiency

What do you think I should do? I was saying they might have got two hot because the first day on HPS I DIDN'T have a fan but I do now.

This isn't due to heat or burning. The is most def. nute deficiancy. Looks like not enough nitrogen or magnesium.

They are in that scotts soil that feeds for 4 months. they have only been in there like month in a half mabey two months. Do you think its time to start giving nutes. Is there plant food I can get at home depot, until i can order some fox farm or something.

could be the soil causing some sort of nute lockout for some strange ass reason that I dont know of and probably couldnt explain....:joint:
