Sour Stomper , Sour Crinkle , SODK X Sky Stomper

Crazy fast growth , transplanted day 7 , roots were bursting out of the small paper cups, 1 seems to be lagging behind the others but will continue for another week like this . This time I am growing in half lightmix and half plagron batmix . Seems like there could already be signs of nute burn on 2 seedlings . Few curling leaves early on so have raised the lights to around 22-20 inches from tops. Given half strength nutes after transplanting . Will follow up with phd water , maybe some seaweed or cal mag . Strains are ~ 2 x Sour crinkle , 3x Sour stomper and the freebies 3x Sour orange diesel kush x Skystomper by mephisto genetics . Any tips or advice would be appreciated thanks for stopping by . Hoping for a decent grow and yield like last time . ✌️
