I run 3500K 80CRI with excellent results. My former partner at HLG says he's seen impressive results from 3000K 90CRI chips.
I think anywhere in the neighborhood is going to produce well, that's part of the advantage of broad spectrum LED.
Run LED lights grows warmer than HID ones, to encourage optimal transpiration rates.
If resin stimulation is desired, don't try to split the difference with more blue or higher Kelvin chips; by far the most efficient and effective approach is to use UV T5 lamps. You don't need much.
