So some days, 1 of the 2 of each strain (2 total) look like its getting curling of leaves. Same water time and amounts. I've started to rotate the girls to see if its an air intake issue. Any Ideas?? Any help is welcomed.=D
They don't look bad so that's the best thing. Try seeing if they perk up and straighten out when watered, otherwise the air flow like you mentioned.
The biggest thing I would consider is over or under watering because it can also cause root problems. You can water with some hydrogen peroxide to kill any possible rot and also boost the oxygen at the root but that's a short fix. 👍
