Yeah , my last grow was in Promix HP and the plants were looking a little pale. So I up'ed the solution to 7gm of MC and 2gm of BE.
The plants got greener as expected and started their stretch going into flower.
What I have been noticing working with MC. Is that depending on your grow medium. Your plants have to be happy with the calmag situation first.
The problem lies in trying to correct the calmag as seedlings, then causing a lockout for the MC just as their need for nutes is begining.
My concern with the new MC is that the calmag has been corrected for veg, but at seedling stage, there still is a shortage of Magnesium.
So 50 ppm of Magnesium in RO for the first 2 to 3 weeks, then 1gm MC there after?
Waira sums it up quite well say'n let the plant tell you what it wants.
We're gonna get this right eventually folks.
Kinna like the Lucas formula, but with without all the chemistry of 3 bottles
