Calculating element amount in two part fertilizer

[Willy.Balls]

Hi.

Does anybody know how to properly calculate the amount of an element for example P in a two part fertilizer?

If I have powder part A that is 10-0-14 and Part B that is 14-14-12 and I'm mixing 1g of each I know I have to count only the amount that is in 1 g of part B since there is none in part A.

What throws me off is Canna Coco A+B. It says that A is 4-0-1 and B is 1-4-2. But on the bottle it says that together it's a 5-4-3 fertilizer.

That means if I use 10ml of each I would have to count 4% of 20ml which I think is wrong. Since I'm using only 10ml of liquid that contains any phosphorus. (part B)

Does anybody know why they are labeling two part fertilizer like that?

Cheers

Ok sorry. Figured it out. It makes sense when you count 30ml part A and 30ml part B as 30 ml total fertilizer. Since the water in fertilizer becomes irrelevant in 10l of water you are mixing it in. God damn it my brain is fried. Gotta make break from smoking this shit.
