The 2 new ones I dropped I ran 2gm-gallon through the soil before I planted. I figure it’s this soil and not the MC. Appreciate the help. I need to find a good soil mix for the next grow if someone has one.
If you're feeding Mega Crop anyhow, why not just use a blank canvas like a peat based soil-less mix instead of soil? That way you know what they are eating rather than guessing what's in, or not in, your soil. There's a recipe for a soil-less mix in my signature. Three ingredients that are fairly easy to find just about anywhere and any time of year.
