I know I should have probably started a different thread, but have too many as is.....you can see the set up, 150 watt HPS maintained at about 3"-5" above grow tips, here comes the yellowing AGAIN. This time it doesn't look the same though. First grow the yellow effected entire plant, which you were helpfull enough to diagnose for me...(nute issues), but this one seems directly related to the lighting??! If you look at the pic in the center(arrow) this top is directly under the center of the HPS bulb (checked heat...OK), and the farther out the tops are the darker they are (healthier), Suggestions? or Comments?...I am afraid to raise the light much more as the stems will stretch and get too tall for the space, and if I don't do something quickly, I will end up with the same wanna be buds like last time on the Sativa's. Need more pics? more info? let me know.
THX ANG for the HLP
