What is wrong with this leaf? The rest of the plant is pretty well, I mean, maybe is not at full potential but it has never been sick till I saw this. It's the closest plant to the fan, could it be the reason?. Any comment will help, thanks a lot!
How close to fan / what’s the intensity? Is it constant, direct trashy wind? Or is it oscillating?
I have no affiliation with Bonanza seeds, never been a customer, but this page they made will be helpful to read. Good luck
