After looking at the pics, I would say veg a tiny bit longer imho. I try to trim it so everything is at least 10 to 12 inches off of the pot. My humble opinion is, you might have ph problems, possibly from over fertilization, or drop off once the fertilizer hits and sits in the soil/medium. Is so, a little crushed oyster shell goes a long way. After looking at the pics of leaves, my opinion is a magnesium deficiency. Again probably caused by ph. I've had magnesium deficencies along the way and it looks similar. For some reason unbeknownst to me, plants under LED tend to require a 25-30% increase in Calcium and Magnesium. Especially towards bloom. I've experimented with light distancing and with LED, plants seem to do well if I keep them at least a 12 inchs or so away from the fixtures. Otherwise the light from the fixture doesn't have enough space to "blend" and diffuse. Closer than 12 inches and I have had bleaching and burns on my leaves and flowers. Plants are tough though, I think that's why it got nicknamed "weed". Ease into food regiments, and they usually take it. A cheap digital ppm and ph meter kit will run you 20 bucks on Amazon, and save you hours if not days of frustration and nail biting. 6.8ph for soil seems optimal. If you're unsure about doses, try and find a nutrient line up with a recipe to follow until you start feeling a bit more confident. Look up nutrient ph scale charts. It will give you a visual reference as to how ph corelates with nutrient uptake. Happy growing and I hope my short story helps. Lol!
