This is how I do in Coco mate. There's also a hella lot of other chat in my thread but that's how I like it. For a beginner in Coco.
I'd recommend using advanced nutrients seni grow and bloom pH perfect Coco line so you can pay less attention to what's your pH and ec are to an extent and spend more time listening to what your girls are telling you. I'm guessing it's a new grow environment too. If so you will have to spend a bit of time dialling that in. More so than your feed regime to be honest. Because if that's out what you put in the base isn't really worth much.
Hope this at least gets you on a good start.
As to Coco I use £1 blocks from a poundshop. A name doesn't matter cos I flush the shit out of it wherever it comes from
