Sensi Skunk Winter Shed First Grow

Back to sub-zero outside temps, although the girl is shooting up at nearly an inch a day. Google suggests this is the stretch phase, so quite normal. Still worrying as the grow tent is only limited height, so can't keep this growth up for more than 3 weeks. No sign of significant pistils yet, but they are starting to form, I'll hope it's just the cold slowing her down a bit. Increased the feed slightly.. Still only half of the minimum recommended by the feed company :- It took weeks to find the level where the leaves weren't clawing... At least for my second grow it'll be fairly spot on for the nutrient levels from day 1. Did some mild defoliation to remove manky lower fan leaves and micro-bud sites from the lower 6" of the plant, and removed 2 big fan leaves from near the top that were blocking some of the higher bud sites
