You know what, screw you. You said you had a haze in there, I gave you info. You don't want it, have fun fucking around with your pre-fertilized soil.
For your information, I RARELY post on here stoned and this is NOT one of those moments.

Edit: You clearly state 'MG Organic' under the 'substrate/medium' section.
stinkyattic Reviewed by stinkyattic on . yellow/purple/grey seedling the leaves on 1 are curled under(1st node) also yellowing and now with grey spots, a purple vein in center of leaf. others arent curling under but are turning yellow w/ gray spots. growth is really slow for 24/0 schedual. Younger ones are still working on their first node and have nice deep green to them but the few that arent im concerned about.. Im using happyfrog soil in 5-7'' pots, wqatering with tap water every 2-3 days. Im curious if there is a milder soil out there for seedlings. Rating: 5
