Defoliation for better ventilation?

leave as much as u can till after stretch, If stuffs in the way of you doing stuff you can get rid of a few, i usually do around d21, net before flip, you can always add another if/when needed

Nah, should be ok. ensure it has room to strech up and keep the light in a good position as not to stunt growth.

Also, youre going to be watering and feeding pretty much everyday in flower with that pot size. Fabric pots tend to dry out quicker than solid ones. I suggest you pot her up one more time, give her at least a week to root and then flip!

maybe some overlapping leaves that cause condensation / standing water would be wise. just be selective. Leaves do several important things including the 'lungs' of the plant. you should never take off so many that it'd cause a stress reaction. really shouldn't be an issue as to when you remove a limited number, as few as possible, leaves. if you think there is a risk of mold or infection, don't wait. The plant won't react adversely to a small percent of pruned leaves.

Hey, i would wait until the stretch is over and then evaluate if/what you want to cut, looks like you have plenty of space for ventilation though. Are you sure you already want to flip? That plant is not going to fill out your grow tent, i think you should wait another 1 or 2 weeks. Depends, if you want to use the net for training you can put it on now, if you want it for support i would also wait for some stretch first. Good luck!
