Fastbuds blueberry

Plant 1 dry weight was 106 grams, the buds turned out really airey when dry, but i harvested a little earlier, the taste and smoke is superb very nice night time smoke. Plant 2 is down and hanging, if she turns out same as plant 1 probably only going to be 60 grams when dry we will see. Plant 3 i do not know, she is putting on weight but also turning yellow, we will see. I think my main problem is the cheap blurple lights they very well but do not seems to be able to produce dense buds, hoping to upgrade to fce 4000
