I have for thee, these questions three...
1. Does coco need to be watered every day?
2. Should I ever be watering without nutrition?
2. Can coco be overwatered? (YT has led me in different directions so I am pretty confused on this point)
Ftr I am growing an array of strains (mistake I know) in coco (obviously) with perlite under led lights in a 4 x 4 tent.
Every environment creates different situations. My feed/water isn't much different then with my soil. I alternate feed-water when they're young and only when they need it. Some plants as they get more mature and demand more could end up water/feed every day, I've had a few especially when I grow them larger. You can still do knuckle deep dry test in coco just like soil. If your a little late the girls will let you know.
