ok so here it is.
After comming back and seeing how normal turned into overfert again I decided to go for it. flush... nah, I prefer leach, that word sounds way better
) So This is what I did. I attached hose to my tap, it happens that I have it for raising pressure of boiler system in my apartment, so I was very happy I had it. So I was able with the hose to make thin high pressure stream into 2l bottle aerating it with bubbles. 3x times water of soil quantity. Ok. Since my container is 22L, I went with like 58L of water. And was watering with 2L bottle, so I had to high pressure water stream 29 bottles. My wife facepalmed herself when she went into the room I was working lol. Carpet was wet in 1 meter radius around my working place lol I even managed to splash the ceiling. yup that hose was surely going wild..
Medium was placed on a washing bowl and everytime it was filled, I was dumping the water to the sink. Don't know if water had to turn colorless or not, but from dark yellow the leached water in the end turned yellow. One thing for sure, after leaching those yellow perlite granules turned back to white again. At least top ones.
The soil pushed down quite a bit. A bit less then an inch. but it was only a week when plant was upcanned, so no wonder that in went down that much.
After all the leaching, I made some 3-4ml/L of grow food. 2 liters of it. and poured onto the medium. since soil was wet enough already, water just went through.
Hoping for the best I placed the plant under the hid, 15min before the light went off and left it to rest after wetful day

This morning I checked on plants and I was pleasantly surprised. The bright green returned, but this time with quite some growth lol. here are the pics.
1st zamal yesterday, the rest are todays photos
Destroyer. Looks like her height was handled. It's still getting bigger, and her side branches as well, but streching is not the thing she's worrying about. Now she's like 12" tall. I still have 1' and a bit left for her.
This is a second day when it's quite humid (50%) and hot, 82F outside. Hopefully temps inside will not go over 90. Anyway it's very humid outside, feels like it will be raining with thunderstorms some time soon, so I'm positive.
