Hi Ase! Thanks for checking in! I’ve had a bit of chaos for my second grow on. My first grow was 2 photos. My second grow ended up being mislabeled seeds, and what I thought were photos, ended up being 4/5 autos. The only actual photoperiod of the bunch is my current Blackberry kush quadline. The rest that you see are autos in a second tent, that I’ve been crash-coursing through.
Unfortunately when I had some of my health issues I didn't keep up with all the journals I bookmarked so maybe I'll have to go back and read. I would get rid of perlite altogether and just grow in straight coco and a lot of the pictures you post have the coco on top looking very dry. Usually fan leaves will show signs of overfeeding with burnt tips but they also can be caused by letting the coco dry out too much. I'm not saying they look bad as the last few updates of pictures show them looking pretty good but just a couple things I could tell off my quick skimming. Autos can be super finicky and because of this I really don't like to grow them. I like to be in full control the whole time.
