What ratio of compost (cow & garden) can/should I add to an hp promix/coco mix in a 5 gallon?

Is your goal water-only, or are you going to feed them too? Autos, or photos?

Thanks, I was gonna add that I have bottles of medione, calmag and microbes.. twenty20 autos.. I don't need water-only but don't want too hot of a mix..

I don't have personal experience with most of what you're working with, so hopefully some of the folks that do more hands-on soil mixing with your type of stuff will chime in

Thanks again..not sure what I'm working with either.. second time growing autos outside. Soil is quite old..reused in different sized pots..ammended each year with lower amounts of compost etc.
I was figuring 12L promix 5L coco and only 2L of cow/garden compost to be safe and feeding mildly..
I just realized that it's not 1999 and this is something I can just write the breeder about..hahahah
