Hey bro! π
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 is below the substrate surface, there should be that much above the surface! But you've done some trimming, and the root system is definitely bigger than the top! So transplanting is needed as soon as possible! π
Usually, you transplant into a pot that is twice the volume of the previous pot! This is a proven practice for transplanting plants! π
Good luck, my friend! βπ
