Coco is generally very low in nutrients like nitrogen. It may have a little more calcium but I'd be feeding for sure. You should buy some earth worm castings my friend. I hope this is a helpful answer.
I'm fairly sure nutes for coco have a different NPK value then ones for soil. So it may have more of one element in then is needed in a soil grow. I tried coco nutes in DWC once but had to get hydro nutes after a few weeks because the plants didn't like it.
