Auto White Widow - First time

Good week, they rooted the whole pots and confess I've been using Great White Mycorrhizae every 2 weeks since I've started maybe it helped lol had a lot of height added and LST’d it back down, they were droopy from not being fed enough earlier this week and drinking a lot more, about half a gallon every 2 days. The topped WW is the tallest and the widest of all 4, def recommend topping for this strain as long as its growing quick and healthy, if i could go back I would of topped my biggest and leave the smaller ones alone. This is end of week 5 and didn't take pics of the pistils unfortunately but they all started showing them, about 5 days apart so a few of the plants, the shorter ones will probably be harvested earlier.
