Welcome @elpolloloco to the community. If you can share your setup there is a form for that here. That way we can see whats under the hood to better understanding how your setup.
I’ve been using the GH Flora series for a few grows. Additionally I am also a Hydroponic farmer, coco is considered hydro, if you didn’t already know. You’ll have to feed with each watering unless you are having issues or just want to flush.
Here’s a Flora chart with feeding guidelines.
Good luck with your first grow.
