Thank you for the input by both you and King. Calmag is at max according to the bottle but I can put in a little more no problem. 

When it comes to phosfate , you could well be right. I have dosed according to the Terra Aquatica Tri-part regime and right now I have measured up as if I was in pre-flower. The bottle called "bloom" is the one with the most phosfates and I havent spent much from it yet. This will increase a lot from my next feeding on.
