Leaf curl in veg

How's it going I noticed some pretty bad leaf curl as of a few days ago on my plants. It popped up after potting into 1 gallon pots with Coco loco .
After I noticed it , I did a pretty heavy flush followed up with 1/2 str nutes at 5.8 ph. That was thref days ago and it seems the new leafs are still cupping a bit . Any idea on what's going on here ?

I would flush n not feed for 24hrs. Give em a break n then go half on the food till they looked better n go back to normal.

I flush after every third feeding as well. Let your pots get dry properly too. It could be over watering.

Looks like overwatered during transplant, very easy to do even in coco before the roots fill out, then the flush made it worse. If the media is wet, let the pot dry out until it gets light, give the roots a chance to fill in.

Overwatered

Here's a picture of a batch of smaller clones (they where stunted pretty bad compared to the rest of the batch of clones ) that where potted the same day as the affected ones. Same soil , same watering schedule ECT. but different strain. They didn't have the best root structure on re-pot day as I would have liked but i didn't want the watering schedule to get out of wack so I reported them with everything else and now they look the healthiest out of the batch , just shorter.

The ones with the curl had big health roots (tho maybe a week away from being rootbound ) in redcups. I waited till the red cups where almost dry before repotting. The flush seemed to slow the curling down. Not much worse but def not better. I'll make sure to dry them out good before the next watering. They already have tons of healthy White roots growing into the one gallon and they are starting to dry up .

I have never had issues with over watering on the first watering after a repot , but hopefully that's what it is and it will work itself out .
