Hi, a month ago i purchased feminized early skunk seeds. There are doing well at about 8 inchs already and looking good. I was wondering if multi purpose compost would be ideal for the entire grow? Also i have recently noticed small yellow bugs on one of the plants, they are in pots dotted in between a few stinging nettles and next to a blackberry bush. Would using a pesticide affect the taste of the buds and the yield? I can post pictures if need be, any help would be apreciated x
