Blue Dream

From the leaf damage on week 8 - it looks reminiscent of either a leafhopper (strip damage), or spider mites (pinprick damage). I just finished the same strain and they were susceptible to the same thing, esp the spider mites. Just keeping them in check is a chore (complete removal seems almost impossible), but it doesn't affect yield or degrade performance. Check the undersides of the leaves. I hold mine by the stem and rotate them 180. If you do find them, they'll look like dots - adults are easy enough to kill just by gently smearing the bottom side of the leaf, the eggs can be harder depending on how many there are. Sometimes I'd just pinch the whole leaf. Leafhoppers hide on the stems in the middle of the plant and will come out to eat at night.
