If you found aphids, You still need to spray your other plants, if they were in same tent for sure, they are migratory colonizing little bitches. I would spray even if separate tent just to be safe.
You gotta do it at lights out, and get under all fan leaves.
Also just a tip I learned on here, at harvest day, get three 5 gallon buckets, and triple dunk rinse your stems when you chop em before hanging.
Will get rid of all dust, debre, and .... bugs, both alive and dead.
