Is it ok to use sensi cal mag Xtra 4-0-0 if run out of Botanicare cal plus 2-0-0? Or is it to much of a difference? Would you use less sensi since it’s higher?
Personally, I would go for it, that’s me, but don’t follow me
You can always “test” on one plant or like you said reduce the strength
If you only have 1 plant, go for broke, a flush would fix it
