I don't think that's good.
I don't use tap water for my seeds/seedlings.
I use bottled water and even distilled water to germinate my seeds.
Chlorine may help to kill slime and mold but it can also burn your tiny little root hairs or kill a seed.
I don't use tap water on my plant until it's well established and even then I let it de-gas for at least a few days.
I'm pretty sure I could even kill an established plant with tap water straight from the tap to my plant.
I'm thinking distilled water with just a light dose of nutes for your clones.
Even too many nutes can kill a tender clone.
The straight tap water is doing great for everything else. In my previous batch I tried RO water and it didn’t change anything. I felt results were even worse. I popped and watered my seedlings with my tap water straight from the tap and they did great and look great.
I buy into this thread here when it comes into chlorine and cuttings.
Chlorine is the missing link
