Clone leaves curing up at 2-3 weeks

Hey folks

I can't seem to figure out what is happening with my clones. They're about 2-3 weeks old all have a tap root that's popped out the rockwool already.

I'm hoping that they've got too much humidity, as I have them together with my seeds under a dome. Can anyone confirm this? I gave them a 150ppm calmag water 2 days ago, which was 1 day after the leaves started curling. Some of the old leaves have started yellowing slightly, but the weird brown and clawed leaves were that way from the parent, I popped it in rockwool as opposed to throwing it out and seems to be growing. Temps sit around 23-25c or 73-77f.

The different shades of green striations on the leaves make me think that it's a pH issue. Did you pre-soak and pH adjust the rockwool first?

First thing is clones do not have a tap root.
Second is a good cutting from a healthy mother should not take 2 weeks to root enough to be left in a dome. My dome is only on for the first 3 days if I use a dome at all, it's when my humidity drops below 50%.

Yup, it's such a bitch to ph pure water that I added the 150ppm calmag to make it a bit more stable. Humidity where I am is around 35%, so they needed the dome.

However I realise I gave them way too much time, they're under some big lights and doing much better!

calmag does not help to root clones and is not the way to stabilize ph.
buy a bottle of water and use it exclusively for this?

the leaves die off on the lower parts of my clones regularly. the plant is disregarding them and trying to concentrate on new growth,
is my thought. and some times it will take a week or two for them to really start growing after being cloned (having roots come out the bottom)

I have never fed my clones anything except water. if it doesnt root that way I dont want the weak bitch in the stable anyways.
see the taco leaves? thanks cal mag. and if you feed anything now they will burn more.
they are all alive, lazy for the dome providing water through the leaves, why root then....remove dome, stop watering until cubes are dry to the touch, then dunk/soak and repeat. roots in a couple days man, relax
