Those are all beautiful plants but that 91 Chem is calling my name. Any chances of getting that cut in my hands? There are a few peeps on this thread that can vouch for me.
I have been considering switching my hps/mh bulbs for LEDs (California light works) but you and @MichiganMedGrower have me reconsidering switching to LEC. BEAUTIFUL grow. Well done.
How long have you been running them like that? I have not had success finding a good schedule. I have ran them like you and they cooked my plants in a matter of a few days. The thread is in my sig. Are you sure you have the Pure uv bulbs and not the agro uv-a bulbs?
