Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Been discovering these little burns and holes on all the plants, Pic 2, 3 and 4. I'm assuming the burns are the precursor to the holes but I'm unsure, maybe they're not related. Any clues as to what this is. I want to stop it ASAP Rocky
