Lst with pipe cleaners all week and Fed nutrients at the beginning of the week and another pH 6.0 watering at the end of the week with plain water, started smelling the day before week 6 very slightly it's a musky smell
I grew a pineapple express twice. First was my absolute first time and only yielded 2 grams(also a cat invasion actually surprised it even made it at all.). The second was 6 grams growing with zero alterations just environment. I found her to be very sensitive. I am willing to bet that going Zero Nutrients would be ok for this one. (Ocean forrest) The smoke however was fantastic pre-optimum cure. Your girls look far better than mine did. I also feel that I didn't have strong enough light at the time to really produce. Which LED are you rockin'? I'll work on posting my back log so I can show you what I dealt with. I let it go Natural both times. You are already doing better than mine :P Which didn't take much Lol.
Ya I've been giving them minimal nutrients almost 1/4 recommend dosage because I've heard autoflowers are very temperamental and it doesn't take much to damage or kill them, I picked up my light from Amazon it's called the mars hydro 300w grow light
