GCS - Pineapple Auto (first solo grow)

Plant #1 (on right) is going to be a big girl I think. Bud development is nice, starting to form first crystals/resin, and each top is getting taller every day. Pretty much a dream of a plant for a first grow. Plant #2 (left) seems to still either be a tiny bit behind or struggling with something. I suspect either mag deficiency or some sort of lockout. Left is smaller and not as far along in flower it seems, as well as lighter green shades in new growth. Lowering ph a bit in the soil and gave straight water one time. The plant seems to be adjusting and recovering so far from what I can tell. Did some defoliation to promote bud site growth, hoping both plants finish out strong in this final stretch.
