Hello! Week started pretty strange. I noticed, that ppm in started to increasing, despite I has adding less nutrients. Next day I added pure water and it didn't helped! I decided to change the solution, but not only this, before transferring her into a new solution, I've washed her roots in a water few times. And there were a lot of stuff coming from there. Idk was was that, honestly, it was just not transparent water with something brown in it. But even more, I noticed my Sensizym starting to smell weird, when I was preparing solution. It was 1 week from being expired, omg. I've got new one. Soo I guess it helped. She starting to grow better by the end of the week. As for me, something definitely was blocking that. Forgot to take picture of roots, next time I'll take it ;) I guess for now, I've overcut her. But somewhere here in point where I'll stop to do that and keep it grow how it is. It's important to keep space between buds. I was afraid, that I would cut all of that leaves now, later I wouldn't be able to reach them. Even it wasn't always easy to do that. She didn't drink much during that period of dirty roots, it seems, now she's starting to drink a little bit more.
