Northern Light: time for redention

I'm not paying a lot of attention to the plant, but, honestly, it is surprising me how fast it is growing. The big leaves are monster-like. First week I'm doing something different: Firstly, on day 24, I watered 3,5 L of chlorine-evaporated water with my root stimulant. Exactly the lentil home-made one I explain in my first diary. How did I do it? It is very little water for the volume of the pot, so I just watered around the border of the pot. Soil wasn't dry at all. However, I think this will not soak the roots as they have not grown that much, but make them extend towards the water. Secondly, on day 25, I sprayed very little, just a click, of a fertilizer I had prepared for other plants. It had a mix of NPK, with more P and K.
