Im not talk about new growth. I can see plants doesn't grow like I want. I talk more about eatablish leaves. Can someone see how purple is central leaves vein?
And how light green is veins between each blade just like magnesium def. Can you?

Thanks for the new pics. I do see what you're talking about. Coco is tricky. Too much magnesium and you lock out calcium. Too much calcium and you lock out magnesium.
Nutrient deficiencies usually aren't caused by a lack of one element but an imbalance from an excess of one or two elements that are causing lockout.
Send in a tap water sample to Jr Peters lab and get it tested. It's around $40. Without knowing the magnesium and calcium levels of your tap water it's just a guessing game.
Peace
