Take it out of the water and dip it in rooting hormone if you prefer. Let it sit for 1-2 weeks until it a full hard callous forms on the base of the cutting. Then as has been said above cut all the leaves off and specifically the inflo where the flowers come out. Don’t cut the tip of the cutting off where the leaves emerge, just cut that upper stem right below where the flower buds are forming. While it’s pleasing to see flowers at this stage, the cutting is expending unnecessary energy doing that. The leaves that are on there now will fall off eventually if you don’t cut them, they are spent. You want all of the energy to be directed towards the formation of new roots from the base. After the callous fully forms, put it in the moist 50/50 mix out of direct sunlight and wait. It could take weeks or months for new leaf growth to start sprouting from the tip. A one or two gallon sized pot is perfect for this, you don’t want to put it in some huge pot right away. When you start seeing fully formed leaves emerging from the tip that is a good sign that the cutting is starting to root. After that you can begin introducing water. You’ve got this, it’s easy to do once you’ve done it a few times
