Gavita to QB on the flip to flower?

Hey everyone I was looking for some opinions on my situation. I've overgrown my space and will be scrogging for the first time. I currently have 2 BML 1200, 1 growmau5 chilled 660 light and 1 gavita turned down to 600 in an 8x8 tent. I ordered 2 HLG 320xl fixtures and they just came in I want to build them tomorrow, out in tent and flip to 12/12. Question is, is that a bad idea? Should I just run the gavita then change to HLG next time or should everything be ok? Thanks for your opinions.

Too many variables to give a definite "internet" answer......... But, I wouldn't see how it would hurt if your running out of space? just go for it imo

Happy growing
