Honestly i put my led light too close too my plants last night and in the morning they looked just like yours do so my question is how much lux are you giving these bad boys
Isn't ProMix in fact peat?? I think that's the issue, you're treating a peat based medium like it's soil, perhaps? Not a bad way to grow nor is it "wrong" but I just think the plant is having a slight reaction to how you're growing it.
Overall, the plant looks REALLY nice. Don't beat yourself up over a couple spotted leaves, especially on such a large plant. Prune it back a bit, as long as the spotted leaves aren't widespread throughout the plant, I literally wouldn't even worry about it.
I'm going to let it recover. And flip it to 12/12. I'll do a heavy defoliation and remove all the lower buds and some tops. Kinda lollipoping it around week 2i vote for pruning and feeding. I saw you said you have been pruning, it looks more like you have been topping. nothing wrong with topping multiple times but, thats thick. trim out some whole branches not just tops. and feed it.
