Is it starting? Is this the moment I've been waiting for?

Funny you should say that. I’m seeing where i’m losing some lower fan leaves that aren’t getting light. Can I do defoliation during flower? I’ve been scared to shock them.
I usually do it on day one of flip or as close to it as possible and again on day 21. That's for the heavier stripping of the lower leaves and buds that aren't going to be productive. Then I'll take a very few fan leaves throughout the rest of the grow if their facing in towards the center or main stem and really blocking the light if I can't tuck them out of the way. After the 21 day mark from flip I try hard not to do any major defoliation but that's just how I do it and I try to focus on the lower leaves that are not going to be getting strong light from my grow light to improve airflow and cut down on pest problems.

Yo FCA, question about wind on the colas.... One of my plants is way higher than the other four in my flower tent. If I keep the fan over the tallest plant the rest of the canopy doesn't get any wind blowing right above it. Is it much of a problem if the fan is oscillating but part of the time its blowing right through the top of the colas on the biggest plant? Its not blowing too hard though... Thanks to anyone for feedback on this nagging issue for me
I'd try training it at this stage by tying it down or supercropping it if possible to get it in line with the others so the light is equal among them all. If that's not possible a gentle, repeat, gentle oscillating fan won't be bad but watch them for signs of wind burn like leaf curling or what looks like nute burn almost. Airflow is important above and below a crowded canopy like you're going to have. I'd be more inclined to put one of those fans under my canopy on a gentle setting pointing up to move the air under them. Stagnant air down low can lead to powdery mildew, mold and other crap in a packed room like that if your humidity gets too high. Lots of air movement and good tent exhaust goes a long way to help prevent it. Good luck with your flower cycle, looks like it's off to a good start.

A little selective pruning would be good, but don't go crazy. They'll recover fine. I try to get stuff like that done early though. Like at least before the end of week 3 flowering. The sooner the better to start though.

They look a little hungry too. What medium and nutrients are you using?
When I took those, I had just finished feeding/watering. I’m in Ocean Forest soil since transplanting took the 5 gallons and I use CalMag every watering and every 2bd watering also add FF Cultivation Nation Micro and Bloom. This last time I actually used Micro and grow combo to give a lil nitrogen boost. Pretty much every watering I trim things from the bottom. I have a little oscillating fan that blows under the canopy as well. If I know it’s not gonna ever see light or become anything yummy, I try and take it out…slowly. Like maybe 8 cuts per plant. I’ll make sure and have all trimming done by the end of week 3 so they can relax and become beautiful the last 5-7. Thanks!!

Question, if you have a 6" inline fan running up top & your passive intakes (bottom flaps) are on the floor, is that not enough air movement on the floor level? My inline fan is always on at least 3/10 & when it cranks up to 7/10... i can literally see the air flow shaking my plant leaves from below. Even then a floor fan is suggested? Of course i only have one plant rn, stagnation maybe more of an issue when all 4 create a wall of canopy?

If I had a scrog or a full canopy all the way across the 4*4 instead of separate plants with a little space between them, I'd personally want some kind of small fan moving air down there. Not a big blower or anything, just some cheap oscillating fan set on low to keep it moving more than the exhaust does. I get what you're saying, mine shakes my clones around pretty good on 6 too but when I used to scrog plants I worried about the underside of the net because it's darker and I liked to keep it on the high side humidity wise. It's a balancing act for sure. Too much and you can get windburn and even in extreme cases hermie a plant, too little and you can get mold or encourage mildew or mold. I always try to edge towards a little too much and watch for drying leaves and adjust as necessary.
