Hey bro! 👋
Transplanting is needed, it's obvious right away!
It's time to do it, I would recommend you to get on it!
There's a rule - as much below the surface of the substrate, as much above the surface! But you used cuttings and the root system is definitely bigger than the top! So transplanting is needed as soon as possible! 👌
Usually, you transplant into a pot that is twice the volume of the previous pot! This is a proven practice for transplanting plants! 👍
Good luck, my friend! ✊😇
