Barney's Farm Lemon Haze Auto DWC

BAM! Lemon Haze is growing really nicely and is about to flip to flower this week, if not already. I included pics of what may be hairs at the nodes, got a nice light green color at the tops of the colas, and they are starting to stretch, at least LH 2 is. Surprisingly, LH 2 is significantly larger than LH 1. I thought swapping positions under the light would allow LH1 to catch up, but not yet. I did LST on LH2 Wednesday, but I haven't done it to LH1 yet because she hasn't gotten as large. The tips of some of her leaves are a little burned, so maybe pH or nute burn, but since the new growth and roots look so good I didn't change the water all week. I changed the water today and added week 4 nutes. Still checking plants and roots 2x per day to make sure root rot doesn't develop, but since it's been much cooler up here I think we are in the clear.
