I noticed I have some sort of bug hanging on my leaves. They are cream colored, ovoid shaped bugs(like a very tiny maggot) that I find on the leaf. They are very small. They have been eating the "color" off some of the fan leaves. They also leave some sort of tiny black dots on leaves. I don't know if these are eggs or a waste product of the bug. At first I thought they were whitefly larve but I haven't seen many whiteflies. I noticed them about 1wk into flowering. I've been picking them off when I see one. I'm into the final weeks of flowering. Should I worry?
