Would this prep work?

Hi riu, so the season has roughly started here in the UK. I'm going to do 8 autos outside just for the experience and then go bigger next year if they do well. I can only do one plot under my circumstances as where I am located it's a bit shitty and I have back pain so getting about can sometimes be pretty hard. I'm thinking about using 50% coco block and 50% multi purpose compost, would that be able to absorb organic nutrients properly? The reason for coco blocks is so I don't need to take as much compost. Also what sort of ferts do you think I should go with?

Are you gorilla growing ? That's a lot of coco with no nutrients and fast drainage ? You could have to end up feeding and watering often. You can use scratch in organic nutes that are easy to carry a lot of. Guanos and fish ferts are an option but could attract animals . Be sure to inoculate your soil if going that route, coco tends to be short on the cal mag so be sure to get charged coco or rinse and charge the cheap stuff Mojo to your grow !

Yeah dude guerrilla growing is what i'm after doing. What about if I went 30% coco, 30% compost, 30% ferts like manures and bonemeal, and 10% perlite?

Could be hot, with native dirt sounds better though. what about premixed medium bails ? Easier ?
