Here's the thing about any nute line... you can mix any of the products they sell... You need to provide good NPK ratios for the stage of growth and that's where their feed charts come in - but if you're growing autoflowers, cut those dosages in half. What you SHOULDN'T do is to mix different brands.... you shouldn't mix an Advanced Nutrient's grow nutes with, say, a General Hydroponics FloraMicro... that's just asking for trouble since different nutes lines adjust their individual components to be in harmony with each other. The one exception is calmag... that's pretty standard throughout all nute lines so if you have some calmag sitting on your shelf from an old grow and need it, you can use it without worrying it's going to "conflict" with the nute line you're now using.
With every nute line, if you're going to use both Micro and Grow components, add the Micro into your water first, then the Grow ... THEN adjust your pH..
Good luck!
