My oldest plant, 6 weeks old, has dryed out tips on the bottom leaves. The dryed tips turned dark green, but not yellow so i dont think its a nitrogen problem. The leaves at the next node just started having the same problem. Im using a 400w mh that is about 3.5 feet above the plants. I have a couple other ak-48s, about a month old, that have yellow leaves on the bottom part of the plant so i figured its nitrogen deficiency and I started spraying 24-8-16 nutes and am now waiting to see if that helped. If it does help will the yellow leaves just fall off? should i trim any of the bad leaves? On one of the plants i noticed today the top set of leaves started turning light green. any help and suggestions would be awesome.
