Hey, saplings are about 3 days from breaking soil. I'm in coco coir/perlite, Lux meter reads 8500-10000 (which I've read is sufficient but I don't speak from experience), I water them 1-2 times a day just a ring around the plant about 30-50ml each feeding. Using an HLG 350R basically on the lowest power (again, saplings are getting up to 10k lux). First grow, so not sure if they're stretching or they look normal. Thanks for your help guys!
