Dots on leaves

You don't have to actually SEE the insects... but you most certainly have them and I'd say it was thrips.... but whatever kind of leaf-sucking insect it is, it can be dealt with very easily with either some Dr. Zyme's Eliminator or some Spinosad. Both are organic and both will kill all stages of leaf-sucking insects (eggs, larvae, adult).... Dr. Zyme's is also a fungicide but that doesn't come into play here. You can use both throughout the grow without damaging buds/flowers/taste.... grab one of either and use as directed spraying both tops and bottoms of leaves just before lights out. If you had leaf EATERS, you'd be wanting to use some BT (bascillus thuringenesis)... it's organic as well.. Good luck - get on it quickly before you don't have a plant left!
