Blending fertilizer and nutrients

Any thoughts on blending I have been blending calcium,cheleated iron, magnesium , along with a quality 10-10-10 plant food has any one else tried any blending and what was the out come

If it's a quality plant food (and good soil, use dolomite), you shouldn't have to add micro nutrients like that.

I blend fertilizer products to get custom NPK ratios. But, not to fine tune micros like that. I could see blending a high-N fertilizer in veg, and a higher PK fertilizer in bloom. That could be worthwhile. (But, some people grow high-N all the way through flower. Others grow 1-1-1 ratio like you mention all the way through too.).

Very true thanks for the reply
