Can't figure this out, please help! Medium - coco 80% perlite 20% Nutrients - Gaia Green Organic 4-4-4 Watering at ph of 6.5
That's probably your problem .That light should be well above those little ones. Lucky you can fix sunburn . Move the light up or dial your ballast down if possible.
Nutes could be a cal/mag issue - I would look into something better - I used alaska for a year then switched to Canna - I will never go to anything else - Canna full line is unbeatable and perfect no extras needed
I’d dial back to 50% or 75% on your ballast for now. 24” is fine in my opinion. Lose the HPS bulb, and switch to MH bulb. What are your temps and RH? I don’t use those nutes, so I’m not familiar. What’s your feeding schedule? How often are you watering? Sent from my iPhone using Grasscity Forum
23-25 celsius 45-50 humidity coco was amended with slow release nutes before planting seed watering every other day
I think they’re under watered. I water every day in coco. At first I thought possible nitrogen toxicity, but it doesn’t look like you have really dark leaves, does it? Sent from my iPhone using Grasscity Forum

Had same issue with the claw and very green fan leaves. To much Nitrogen, I flushed all good now Sent from my SM-G965W using Grasscity Forum mobile app
Doing way too much for a light problem. Ask anyone and they will tell you, as young as those plants are, that 600 hps was way too close. Take advice as you will, but your putting in ALOT of work for an easy fix . Cheers mate
