I doubt it has anything to do with the spectrums.

Obviously 1000w hps radiates a lot more heat. What was the ambient tent temps during flower? Sats might prefer a warmer environment, even during flowering

I looked up the light and was disappointed by Fluence's lack of transparency as to which spectrums, and wow the price is awfully rich

I still use an original BML Spydr 600 9cir 2014) that Nick collaborated with me to develop, which for him at that time was a unique spectral blend, combining ~ 80% neutral white and warm white diodes + ~ 5% 450 blues + ~ 15% 630 reds

I would just say that LED environments are different in remarkable ways. The waste heat in metal vapor light sources has a tremendous influence in enclosed environments - and you just don't get that with LED. So look for other variables like temperature and humidity. VPD becomes a thing - because you don't have these hot glass tubes as a dominant humidity influence.

I've found that I cannot use alot of the advice given for those envirnoments. I have to measure and figure out what is limiting any particular stage.
