FastBuds/Mephisto/ILGM mix

VPD down to 1.3 due to lower temps and higher humidity. Changed light from 24/0 to 20/4, and no noticeable change. I moved the plants around so the taller plants would be under the same light. Used Big Foot myco for the first time. No noticeable change. Smell increasing but not that strong. Will skip a feeding because of possible nute burn. FS - 22" (1" increase). Leaf tips burning more, which I suspect is nute burn. Starting to fill out. Small amount of dried green runoff in saucer LCC - 8" (final height). Looks completely filled out. A little bit a white mold on top of soil, and the fabric pot is turning brown for some reason BPP - 13" (final height). Looks done aside from pistils and trichomes changing color WW - 20" (1.5" increase). Unexpected growth spurt! Leaves look bad again, and many died. Maybe this one is having nute burn too
