First Autoflower Grow

Beginning of week 3 veg still using lst to keep canopy even and the girls seems to be responding well. All but the lemon auto (a week behind) are preflowering, the expert gorilla seems to be fast and is starting to stretch, Jack auto is showing the thickest veg hoping for a decent yield if I can keep them alive throughout the entire grow lol. I did snip 1 or 2 of the largest fan leaves off each plant that seemed to be hindering some new growth underneath. Took awhile for substrate to dry after last weeks flush with just calimag. Runoff came in at 5.8, some plants may be showing a deficiency but blue dream showed some nitrogen toxicity possibly from ph? Will full feed tonight.
