am growing in seedling soil and at the very bottom of the cup i have 3 to 1 seedling to supersoil mixed to help acclimate with the transplant into supersoil. My temp and rh are spot on. Overwatering can do this? I didnt think i was overwatering. I used a spray bottle every other day watering at the base of the stem and not saturating the medium. I stopped the every other day and just every 4 days now. I used recharge twice. It was getting better but after my last watering half of them got worse and the other half had a growth spurt?
Just by looking at it, it does appear to have signs of overwatering. More info: https://www.mrgrowit.com/post/over-watering-cannabis-plants
