Do I add the NPK's of all my nutes and additives together to get total?

[toostonedto]

Sorry if this is a dumb question but I couldn't really find an answer. I'm basically just wondering if I add all the NPK(and other micro's) values together to get total?

Example; BC Grow is 1-3-6 and the Boost is 3-2-0...if I mix at recommended amounts, will my total NPK be 4-4-6??(the two added together)

Thanks

In theory yes, but the release rates are what are important when your mixing and matching, if not the same your plant will suffer.

Ok thanks, but how do I determine release rates? And how would I match them so not to make my plants suffer?

By using the same brand of food and adding a couple extra's like big bloom or what ever. You should not mix and match basic foods to come up with a number.

In that case yes but you usually don't add nutrients in an equal amount, it's generally more of one part than another.What you really want to know is the total PPM of each element at a specific dosing amount. For example, if you dose 5ml (1 tsp) to 1 gallon of water of a 1-3-6, you would get an N-P-K profile of approximately N13-P17-K66. If you dose the same amount of 3-2-0 you'd get an N-P-K of app. N40-P12-K0, If you put them to the same gallon of water, you add them together to get a profile of N53-P29-K66. You can manipulate those ratios by differing the amounts of each used to create a specific nutrient profile.
