Looks fine to me. Just make sure to rinse it well and possibly pre charging it with a little cal mag before planting.

I prefer Roots Organics compressed coco...it's a very fine grade of coco, vs. it having large pieces of coco husk in it. Regardless, I would gather what you listed will work fine. My only advice to you would be just as noted above. Wash this stuff out...and when you think you've washed it out enough...do it again. Once you've gotten all the tannins out of it, pre-charge it with a 25% mix of your feed and thoroughly saturate the coco. Once the excess feed has drained off the coco, plant it up and go!

^everything he said .

Works like a hot damn.
