So, some people were noticing Magnesium issues with the older formula, depending on strain/lighting/medium, beyond what we initially anticipated. So, with the new upgraded MEGA CROP, it has more Magnesium (and chelated Calcium) which should greatly reduce anyones need to add CalMag supplements.
Also, the other issue people had was too much N for flowering, so we boosted the PK, and did not boost the N. So, its the equivalent of having a PK boosted added into the new formula, so it performs better in Bloom/Flower without needing anything else.
So, we are just working to make it the best product that we can think of, and will do annual updates as needed. Although we are pretty happy with the current state, so we won't make any changes if they aren't needed!
So about your old formula, is still the core MEGA CROP good formula, but mainly with added Mag and PK (which wasn't even a problem for most people)
Cool, thanks mate.
Have not experienced any of those issues with my last indoor grow. Am using it at the moment on my outdoor crop, so hopefully it performs as well
