OLD HEAD Photo x Gelato Auto

Experiencing major issues. Originally I thought these were light sensitive and they were being light burnt because they're are in the exact same setup as 4 other strains that are doing fine. So I changed out the light to a blurple with just the veg switch on and backed it off to 36". I turned a fan down in case that was an issue too. This week they aren't up-taking any water! So they must be in a lock out but they have had all the same nutes water and recharge as all the other strains. Not quite sure what to do other than scratch in some bio-live and recharge and Cal/mag/iron. Maybe the roots rotted because they weren't started in small pots and the roots got too wet. ----- Since they are doing terrible I germinated 3 more. This time starting them in smaller containers. I haven't grown photos in a few years and started the first run in 5 gallons from seed. Maybe transplanting will help with root structure.
