i am in the final week of flower before harvesting, and i have a winged root aphid problem and they're laying eggs on my frosty almost finished nugs. i read that the larvae can cause me bud rot, and with only 7 days left i want to try my hardest to save the grow. what can i do/use in these last 7 days to get rid of the bugs? and can the larvae really cause me bud rot this late in the game?
