Looking for a good 'Mother Mix'

I'm looking for a good 'Mother Mix'. Currently my mother plants are in a coco mix but that dries out too quick for my liking.

Preferably something that can go 2-3 days between waterings.

I grow in a coco/perlite automated DTW setup and have never messed with soil but I'm not opposed to it for mothers.

Any suggestions are greatly appreciated. I'm trying to get an idea of what other people are using.

I like keeping my mums and dads in either dwc or big dirt pots and water every 4 or 5 days, foliar fee mostly and top dress with fish bone and blood fertelizer, light and complete.
I like dwc because i can literaly almost forget about them and just add water once a week as well as ph and adjust ec and plants do just fine, i do foliar regularly with organic nutrients and teas though. Keeping mums in dirt can be a bit trickier because things happen a bit slower comapred to dwc and i do not like adding liquid nutes over time and again and leaching out every so often due to salt build ups. So i just top dress and tea them. Also plant recovers slower from taking cuttings.
Mums or dads i need to clone a lot i keep in dwc all others in dirt.

I keep my mothers in a coco perlite mix in 5ltr auto pots hooked to a 40 litre rez, I just fill every two weeks and never worry about them, I barely check on them.
