I agree with lowering if not completely removing vermiculite from the equation. My first grow using Hempy I used 25% vermiculite and then none in my 2nd hempy effort and found no difference. Since then I have only used 100% Perlite in another 6 grows very successfully. I have also increased to size of perlite I'm using to #2 & #3 size. I put the #3 on the bottom 1/3 and then the #2 the rest of the way up.In my experience, using that high a proportion of vermiculite is unnecessary, unless you live in the desert (very low humidity). Otherwise, you may experience issues with slow draining. IMO, good drainage, and the ability to water frequently, is more important than minor adjustments to nutrients.
I also did a comparative grow using MegaCrop and DynaGrow with ProteKt and Grow. I use CaliMagic with both. My first test grow was two BerryBomb clones and had a 50% large yield with the DynaGrow. My second grow is showing a completely opposite result with a current SLH grow. I do feel there are other factors that may have impacted this result. I like the simplicity of MegaCrop and will continue to consider using it in future test.
