Tough week. Did a flush on12/15 for about 15 minutes, had some yellowing leaves all over on all plants so a pruning was done to rid the dying leaves. Since then I've LST the smaller middle plant of the 3, lowered the lights from 25inches to 20inches and started a feed of miracle grow (used less than what's recommend; dont want to chance burning them)and watering on 1220. So far so good. But next grow going to try a hydroponic system and exchange the lights for full spectrum red, white blue hue. Still using yellow tape for gnats which is keeping them under control. Next watering will be tomorrow (on an every other day since the food was store brought).
