Dinafem Critical plus scrog grow

So I am entering week 2 of the 12/12 flip, the ladys are showing sex so hopefully later in the week I will get actual pistils so I can start counting down flower days. Day 9 seen pistils but I had to perform a major defoliation as under the canopy was bad and I didnt want powdery mildew due to leafs sweating ect. Day 10 24 hours after defoliation, you could not tell I done a thing to them, im hoping its just a odd leaf now and then thru the rest of the flowering period. Any advice is welcome guys 🙏 I will be adding more fans for airflow. Day 12 of the flip and the girls are on there way to becoming ladys lol I think there's going to be a few nice kolas in there when done, ordered the new box fan for the floor to create more airflow to reduce the risk of pm and mold. I need to top up soil as roots are showing so under the net I go again. Wish me luck.
