Yup, the rule is when mixing always add the Protekt(Silica) first or it may not mix correctly. You'll see little floatie things in it if you mix a calmag first then add the silica.With the Protkt aren't you supposed to mix it with the water good before adding anything else? I used that for awhile with my younger plants and seem to recall doing that.
My routine would be:
Protekt
Calmag
Supplements
Final Product
So in my case I mix Protekt first then calmag then the SC and BE and finally the Megacrop. I use MC v1 from 2018 so I add the supplements to make up for the lack of nutrients v1 has compared to the other versions.
Thanks for bringing that up Beez.
