thanks for your input

to clarify
14 x 3up(2rb/1nw) = 28rb & 14nw LEDs
8 x 3up(3cw) = 24cw LEDs
total of 28 royal blue, 14 neutral white & 24 cool white.
I'm hoping this blend will give me a nice full spectrum about 10000-14000Ks (not that kelvins mean anything to plant growth) I shouldn't need any more blue as I don't have coral.

I've added hyper violet (hv) k deep red (dr) to try and mimic PAR wavelength peaks

my tank is 32in high so even if i have the lights directly on the tank top it would be 2.5 feet from the substrate. my light will be suspended about 1 foot from the top of the tank. the 40 deg optics will give good penetration getting usable light to the bottom.
