Adding Recharge to an Advanced Nutrients program?

Hi friends. Relatively new grower here.

I'm growing indoor in a 50/25/25 mix of Promix/compost/perlite. I've been using Advanced Nutrients with good results over my last two grows. I'm hearing good things about Recharge and I want to order some and try it out, but how do I add it in to my program? Do I have to dial my normal nutrients back or do I just add the recharge and keep everything else unchanged?

Water it in by hand once weekly, you can mix it with your current nutrient regime or just plain water. No need to ph solution once it’s mixed in, the microbes will do the work.

Do not put it in your reservoir, hand feed it.
