Hi Elsolo,
First of all - great grow so far :)
Raising your light will give the plant even more stretch, which is approached in your case. But try to stick to your light manual (u can check online as well) whats the best difference between canopy and light during veg/flower phase. And slightly adjust it as needed or as your plants will tell you.
I would recommend you topping your plant and do some LST to get all main branches on the same level :) Always top about 3rd or 4th node and then have fun ;)
+ Lollipopping is great to get bigger main colas instead of little popcorn buds below... I would do it 1 week befor transition into flower - cut 1/3 below everything and then leave them for 4-5 days to recover and send them into flower. Next Defoliation should be 21+ Day of Flower and that's it more or less. Afterwards u can always take some big fan leaves or leaves who cover buds below.
If you have further Questions feel free to send me DM :)
Good luck and have fun.
Ps. u can check my current grow - I did topping + LST + Lollipopping and get amazing main colas
