Whats your opinion of coco

I haven't used it yet, but I should probably look into adding some. I test my runoff ph, and it seems to stay pretty stable.
I did have some early mag def when I first started using the mix. I never used coco before, and the mix didn't work the same as the peat/perlite blends. I had inter-vein stripes on lower leaves early in veg. It's been rolling along pretty good the past few months now. I only run 5 plants in a perpetual, so I haven't needed to make any more mix yet.

I mixed my own for a couple years until a found a place that sells BM6 for $25 a bale.
I did a bit research and found a paper by UCBerkeley that recommends 5% pulverized dolomite by weight be added to peat for
container gardening. That was about 3 pounds per 4ft bale of peat.
With the coco in your mix that likes to hold onto calmag a bit of lime should help those early deficiencies.

That's great info. I'll do that with my next batch. These damn bales of peat blend are $40 and up, and they are smaller now too. 3-3.5 cu ft. I used to get bales for $25 also.

Check agricultural suppliers in your area, they won't have the weed tax on peat blends.
I was lucky to find one in my area that I didn't need to register a tax ID. I toss them cash and they drop the pallet on my truck.
