@reza92 imagine if Slownickel read this lol
Posting Molders chart as your proof that Ca causes lockout shows how little you understand about balancing minerals in soil. What the chart shows is the effect each cation or anion has on the uptake of another, to end up with deficiency you must be low in that particular element in the first place. You're also not taking into account the fact that Ca and B together are responsible for driving nutrients to where they are needed inside the plants structure.
Either way I must thank you for the good old laugh I got from your post, best one I've had all week
Cheers
