Hey friend looking beautiful. Just some advice if I may to help out, When the plants have finished their vertical growth, With photoperiods its usually weeks 4-6 of flower autoflowers you gotta kind of watch for it. But with your ladies this close to their end of life you should be widening your temp gap between lights on and lights off to more than 10 degrees less when the lights go out. If we do this when the plants still are growing vertically then we cause them to stretch when we do not want that. So veg & early flower we keep that gap to no more than 9 degrees less when the lights go out to keep them growing nice and compact. But once they have finished that growth vertically we open that temp gap up to beyond 10 degrees less at night cycle and it will now send extra energy into the plants budding process and resin production. It really helps finish the plants off nicely, Each week widen the gap a bit more dropping those nighttime temps further and further. I hope this helps you out ! Also if you have yet to do so look up VPD, Vapor pressure deficit, and how it relates to growing cannabis, Also grab yourself a PAR meter & a thermal laser temp gun if you haven't already to better read your plant tops and get all the potential you can from your lights.
Keep up the great work man, Check out my 200 light 7,000 plant diary & follow my profile. If you ever have any questions please feel free to ask. Happy growing friend!
