Their spider mites my friend, this is not good for your plant. Spider mites have tiny sharp mouths that pierce individual plant cells and suck out the contents. This is what results in the tiny yellow, orange or white speckles you see on your plant leaves. To combat this problem you'll need to use things like Azamax, Spinosad Products, Essentria IC3, or Insecticidal soaps Follow up in 2-3 days with a different method to kill them (you should also re-apply your first method)Repeat at least one more time – always treat grow area at least once after you think spider mites are completely gone. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
