What's up with this leaf discolaration?

What soil, what food? It looks like N def to me. But, could be exacerbated by overwatering? Do you let the soil dry *very well* between waterings? The container should feel alarmingly light?

Growing in coco. GH Nutrient Trio and calimaic, pH to 5.8, though I only got a pH meter recently so prior it could have been off. Just transplanted into new 3 gallon pot and in the process figured out that my old coco was not a good consistency that coco should normally have... I figured that could be what's causing the dying fan leaves that you can see at the bottom (one very pale larger leaf). But i'm confused because this discoloration seems different from the dying fan leaves at the bottom. Which, hopefully, will stop happening after this transfer into better coco and larger pots. I've been easy on the watering as much as possible. Have only watered once since transplant 4 days ago. And only a quart and a half per 3 gallon pot, soil is still wet aside from a few spots on the side (watered yesterday).

Could it be because my light was too close? I've moved it now, but somehow by sheer magic the plants were like 7 or 8 inches away from my 400 W HPS this morning when I checked again (I hadn't for a little while).

Also, on my other plant that is in the background, the leaves are drooping and curl up towards the light when first growing in. That's why I moved it up bc that alone is sign of the light being too high, but this yellow patterning on this plant especially is just weird.

looks like ph lock out

That could very well be a possibility from prior to getting my pH meter. Indicator solution is damned near impossible to guess where pH 5.8 is...
How long then, after starting to water with most definetly correct pH water about 4 days ago, will it take for the plants to be able to recover from this?

just flush with ph water at 5.8-6.3 leave a day or 2 then get back on the feeds

It doesn't look like bleaching. But, it could have driven the plant's metabolism, compounding a lockout condition (if one exists). I.e., needing even more of the nutrients which are locked out.

Sorry, one last quick question lol. Would raising the lights therefore help prevent nutrient lockout or burn in the future at least, or is it the closer the light without too much heat the better?
