If one of you would be so kind as to jog this feeble mind of mine it would be deeply apreciated. There is tiny little white/ gray flakes on the leaves of my tomato plants, it almost lookes like wood ash.I know its a sign of aphids. but I don't remember if its a sign of them hatching or if its a sign of them being eaten. anyone else seen this before? I checked under the leaves and I do have aphids but if thats a sign of them being eaten I'll just leave them alone.
