Just wondering what could be causing my issues here. Have 2 sappy sour x2s here 17 days into flower with 2 45 watt full spectrum led grow bulbs. Getting alot of the bottoms leaves just turning yellow and dying off. A few of the kolas have yellow tips on the very top sets of leaves not under though. I also have some other stuff going on with some of the leaves. Pics included one at a time so you can zoom first is the entire plant second the kola with yellow tips third will be one of the sick leaves.
