Are they in a tray with a humidity dome?

If yes, you're spraying them too often. Keep your cubes moist, not wet.
-Time- Reviewed by -Time- on . First Time Cloning Help!! Hi I have been trying to clone my master kush but with no results. I am using rockwool, soaking them for 24 hours in 6.0 ph and using rooting gel. Cutting at 45 degree angle. I put the clones in a dome at 75- 80 degree F. I mist them 3-4 times a day. I am putting them under 24 watt flour. My problem is that they will be fine for 3 days then all of a suddend they will get soft? especially where the stem part is bending is where it gets soft and drops down. Rating: 5
