Don’t have a clue what’s wrong

Am in day 45, it started growing fast and am afraid lights are to much or to much nukesView attachment 2171727

Whats the PAR ?heat may cause that.check run off water ,see what the ppm is and ph of runoff.use all purple blue light?may wanna get a more wider spectrum lighting system blue and purple is ok for veg and keepin her from growing to fast but you need more whiter light for flower plus some red and uv .that's my opinion anyway but it is what worked for me.good luck man or mam
