Coco/perlite.
I am still getting use to checking the weight of red cups. It’s been 3 days and I figured they seemed a little light.
Started filling the bottom cups until I made it around to the cups on the left side and noticed they had water sitting in the bottom cup ( I top watered last time).
Also noticed some slight fuzz growing on top layer.
After about 10 minutes I dumped the cups that I filled.
Is this dangerous? Anything I can do?
Increase VPD?
This would’ve been the 3rd watering since up potting into red cups.
