I too share this problem as the OP. I have no idea what it is but I'm about 5-6 weeks in with clone-able branches sprouting. Any answers will also help my problem. Thanks in advance
I found cuttings and seedlings respond best with some fresh bottled water. It's already RO'd and PH'd so it's probably the best bet in ur ez cloner. Also, is it a DYI ez cloner or is it an actual EZ Cloner from the company??
