First ever Grow: Gorilla Glue #4 Auto

Explosion: almost overnight all the ladies have to doubled in size, and then some.... the full 4x4 is now filled completely and space management is starting to get difficult. I am noticing they are doubling in size every 36 hours now. The sheer growth is quite impressive. I can probably say that this is the true week of pre-flower: all colas are showing blooming pistils at each apex. Started to use some michorizae friendly additives to support the root growth. Still updating on the LST every other day to adjust and optimise; The GG4 shows the first trichome structures with their distinctive diesel and gassy like notes. I am noticing that the whole grow tent is showing signs of overfeeding. I will begin to both water to runoff at 30% from now on, but only after a long overdue flushing with neutral water in which I will check ppm's all over.
