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.
