Yo.. i'm trying to figure out whats going on with the bottom leaves on one of my girls... i know that they fall off normally sometimes.. but ... yeah... what do you guys think?
When you spray, is it at night or in the day - coz the light will be magnified through the water droplets, although that normally burns holes in the leaf, if the whole things wet it could do what yours has and turn most of it dry.
I'm not sure what standard pot size is.
16 inch plant, may be getting rootboung if the pot is too small.
When a plant gets rootbound, the lower leaves begin falling off.
