The numbers don't mean anything to me. The final product is quite a bit better under HPS. Potency certainly.
I've used HID lighting for almost 30 years. I switched to LED and tried several lamps. I still use them for veg and making seeds. For flower I switched back to HPS. It just produces a better product and the plants seem happier. I haven't seen any Mag or other deficiencies, also not a whisper of PM since going back to HPS.
