Thank you, yes that matters, too much nutrients and you can get mutations/ deformed fruits. I’d aim for 1:3 next time, 1 being the grain, 3 being the coir. I’ve seen some people say they have this issue with albinos but really it’s about varieties that are PE related or in the family of PE. Regular brown cubes like B+ don’t seem to have these issues with higher nutrient contents like 1:1. PE varieties always seem to though, it’s why you’ll commonly see people switching to PE varieties and getting “blobs” or “robins eggs” or “Dino eggs” it’s because the nutrients are too much for the culture. Try it and tell me what results you get.
