So folks, for anyone interested. After all the tips formed these leaves, the tips formed into a kind of bud and came to a stop. Then I cutted off all the tips and she continued to grow normally, like in the first 6 weeks. She is now in the third week of flowering and is looking very good. So all is well with her. I didn't change the conditions, just cut off the tops and just flowered.
Thanks for all your tips!
