This is a few days time after treating with a new fan, and a couple brief sprays of Mg by way of epsom salts dissolved in water, applied to the leaves. I expect to see the leaves stop curling at the edges, which from what I can gather is caused by one of these things: magnesium deficiency, or heat stress/light stress. more details at www.BrotherhoodOfFreedom.com
whats teh salt do?
@therealrockondon epsom salts provide magnesium.
But this problem of curling leaves is probably heat related.
How hot is the room?
@rickythepitbull It gets into the low 90’s. But this one also appears to be the same issue – I was feeding/watering it with a PH well below 6.
