Strawberry pie — Fastbuds

First things first - I missed the last 3 weeks of pics and entries because life’s been a bit crazy. But I’m back and the girls have been doing OK. #5 is catching up being that it was the runt of litter from the start. But it could need another week but I don’t think the other 3 should go much longer. #4 likely got nutrient lockout from an overfeed early in the flower stage and the high heat environment my HID setup creates. 2&3 are lookin like the absolute dankness. Super dense and loaded with crystals. Really smells of sweet strawberry’s too. If anyone has any advice on when to start flushing would be helpful because it seems like there already starting to yellow and don’t want to make matters worse if I can. I’ve only used light organic bio biz nutes.
