What’s happening?

Hey guys, over the last few days I’ve noticed this on a few of my plants, they are only 3 and half weeks from sprouting (growing FEM train wreck) been going light on nutrients and light watering.. like half a liter each.. did The first big feeding on Sunday of half a gallon each.. I wasn’t measuring ph in the begining, sundays feeding was a little low at 5.9ph because I added a ratio of lemon juice to bring it down from 7.4, my temps have been good, have a fresh air intake/exhaust with a booster, a circulation fan.... not sure what the deal is with this, best I can come to is nitrogen but the leaves aren’t yellowing.. help! Haha

I’m using advanced nutrients and coco with perlite added in 3/4 the 4th is some old fox farm ocean forest mixed with coco about 50/50 with perlite.. that’s the only one not showing any signs(first picture) yes I have topped them hence the weird leaf cuts

They look a little crispy to me, might need more water than what your giving them. Give them a good watering and lift the pot to see how heavy it feels, let it dry and lift the pot to see how heavy a dry one feels.stay on that water and let dry schedule and you'll avoid root rot as well. I think after you get on a regular feeding and water schedule you should be fine.
