I don't get it. This is my first time cloning so I'm sure I goofed somewhere but don't know where. I pulled the clones out of the rockwool to check the root system after 2 weeks and no roots have developed. Only a brownish necrosis around the 1/4" of stem. In a panic, I cut it off, stripped the outer tough skin and dipped again in rooting gel. The rooting gel is supposed to be good but I wonder if its not burning them. I just hope I can save them. PH=5.8 but there has been some upward drift do apparently to the water not fully stablized...I guess... Any hints? Thanks, MH
