PC, I'm afraid that your humidome is keeping things too humid. If there's water condensing on the inside of the dome, the humidity in the dome is 100%. Doesn't need to be quite that high- 60-80% max. In fact, if you can remove the dome and nothing wilts, leave it off. Excess humidity can cause you some serious grief.

Humidomes are really only useful for the first 1-2 days after cutting until water uptake through the stem cut is established- and even then I'd debate their usefulness. I haven't used one in many years- my clonebox even has an exhaust fan. The humidity in my clonebox runs about 60% max.

I see some of your stems purpling. Mine did that until I started adding a little nutrient to the water I give the clones, shooting for a weak 400ppm @ pH 5.5 or so. With Canna (Vega) nutes, that's 5ml "A" and 5ml "B" in 10L water.
