I have a mix of 40% worm castings, 30% peat, 20% coco and 10% perlite. What would be the best NPK?
I have some 4.8-12-6 fertilizer available right now.

I hope you have enough aeration. That's not much. And hopefully those are good castings. Most castings are too dense to use 40% in the mix.
I haven´t had issues so far with this mix, the roots look healthy and filled a cup that was the previous container. It´s starting veg I was looking into fertilizers now that I repotted.

Some Azospirillum brasilense inoculant with a steer manure tea would probably work fine for the early vegetative stage of growth. I also recommend mycorrhizae inoculant if you haven't already included it.

Where did you come up with that mix ?

You are running practically equal peat / coco - so what ph are you gonna go for …. Or i should say try to maintain?

Each run at different levels.

I bought it prepared from a local growshop at the very beginning, peat is a mix of white and black peat, supposedly the ph of all the components would balance it out to a 6. Yeah it is a bit sludgy and it kinda gets a bit compact after after watering.

There is no need for “ boutique blends “ for a simple plant …. Especially from a hydro shop.

All of the initial “ feeding “ can be done by available bagged mixes - most needing minor tweak but overall ready out of bag. Buffers and all.

Then you can top dress the same mix as a supplemental feed or “ recharge “ of medium as plant consumes at its own pace. Or as stated a simple dry fertilizer ( scratched in to top soil ) and watered in.

You would find a better ratio of elements already available in those bagged mixes including myco .

Growing for personal use became legal here a couple years back and there´s very limited tools, mediums and so on, the shop has stuff that they have been able to import, so I picked the medium they had, also they do have liquid fertilizers that I see commonly on Amazon from brands I´ve heard, but I have dry all purpose fertilizer much more easily available and cheaper localy, so I´ll look into that.
