Bagseed lottery

This week has been interesting. As i prommised last week i have upgraded the lights to just about 200w.tue to it being homemade i used what i had, the lights ended up being a colder tone. But more light is better i supose. Towards the end of the week there was a noticeable stretch, so there is finaly signs of flowering starting. Plants are looking really good. Started adding more potasium and phosphorus in preperation, before cuting off the nitrogen towards the end of the stretch. Any feedback is welcome, best way to improve is to learn from mistakes, but i feel like i am mising some of my mistakes.
