they look like spider mites to me but it is hard to see, but I agree neem oil should have been used and next time pre spray with neem and azatrol during foiler feeding.
MadSativa Reviewed by MadSativa on . Plant infestation & hard black spots (w pics) Aloha! I am growing, as a first time caregiver, three plants on my balcony in Hawaii. Two of the plants have been harvested. While I was trimming the leaves off of the third for harvest, I noticed several problems. 1. Black hard spots that are on the stem and leaves. 2. an infestation of some kind of bug. 3. the plants leaves have been yellowing for quite some time. I was told this is normal, but that's obviously a lie. Rating: 5
