So I'm at week 8 from seed on Saturday. And I'm trying to correct my ph problems, mag def, nute burn, and bulk the buds up before harvest. I'm feeding ph 6.8. Water and epsom salt only today. And before was 1/4 tb, bb from foxfarm with epsom salt and blackstrap molasses. Should I flush? Or feed it water,molasses, and epsom salt for a couple feeds. I just wanna max my bud potential before harvest this is my first grow
