Here’s an example of a booster soil I put together for my first Auto. Only added 1tsp/gal of Protekt with every watering, and there were essentially no deficiencies all the way to the end of the grow.
For each pound (456g) of base soil (I used EB Stone Recipe 420, but Happy Frog, Pot of Gold, and the like would work with this recipe):
- 7 oz (200g) Kelp Meal (ex. 1-0.5-2)
- 1-3/4 oz (50g) Fish Bone Meal (3-18-0)
- 3.5 oz (100g) Dr Earth Flower Girl (3-9-4)
- 3.5 oz (100g) Powdered Dolomite Lime
- 3.5 oz (100g) Powdered Egg Shell (marinated in vinegar and roasted)
This provides an enhancement of about (0.6-1.9-0.8) to the base soil, along with sufficient Ca, Mg, S, all the micronutrients, and mycorrhizae.
Mix it up with enough pH-adjusted water to hold together but not so wet that water can be squeezed out. Seal it up for at least 30 days, opening and stirring daily. I only use 1 gallon mixed with a gallon of rinsed pumice and put that in the bottom for the roots to find.
