2 month old plant in veg 2nd time growing

This is my only female plant out of 4 and its in a soil/perlite/scrap compost mixture. It has been soaking up the purified water. The Ph is right but i know i need to get real nutrients to promote the best growth! Since yesterday we moved the fan on high and it has always been set on medium b ut i noticed it was getting weak but now its growing like Crazyy!! The compost is great and we use it all over the garden and its crazy how good it works im thinking on using that stuff again tomorrow to feed the microorganisms too.

what do you guys think about super-cropping or anything else also the main budspot on top got real close to the CFL one day while we were out and now it has a real crunchy texture on top haha
