My plant has black dots on the bottom of the leaves.
Does anyone know what this could be?
Thrips shit, spidermites, insect eggs, soil.
Pics would help.
spider mites was my black spots. i would get some neem oil and start treating ASAP and clean your grow area from top to bottom, do this everyday for a week or more so you can break the cycle.
