My current run is off to a terrible start. I accidentally fried the seedlings with too much ppf to start, and I believe the fan in the tent caused the leaf edges to start rolling up.

After a few weeks of very slow growth, I transplanted them into bigger pots and put them in my 4x4 tent.

I backed off on the fans majorly and the new growth wasn't showing any leaf rolling. However there is white, what I'm assuming is mildew growing on top of the soil now because there's no airflow. Also the plants are very weak and floppy, and one of my donuts triploids looks like it may have died for some reason.

I tried increasing power to the fans at the top of the tent, pointed away from the plants at an opposing side until I saw the leaves begin to move gently, to try and strengthen the stems and eliminate the mildew.

Today the leaf edges are rolling again, some leaves are full twisted 180 degrees. And the donuts triploid pheno was laying on it's side and is super floppy and wilted.

Is it the fans? I have 4 different genetics in the tent and they are all showing similar symptoms.
