Clones have been home for two weeks since purchase.
Fluorescent light 24/0

run off ph=7.6

temp at plants=82-87f during day and about 78f at night.

Grown in miracle potting soil. after 1 week i added miracle grow plant food with water maybe a little bit too strong on the mix.

Im curious when a good time to start a nutrient regimen would be. I've researched anywhere from 1-5 weeks after rooting and not sure.

I've since flushed with filtered water put back under lights. No new brown portions yet.

Hopefully you have things squared away by now, but I would also go with a bit too strong a nutrient feeding when small. Generally, if the browning/curling start from the soil up, it's nutrients and if it starts from the top down it's heat. ;)
