Keep the 10,000K light (it really isn't all that blue at all, it will work fine).
Swap the actinic blue for a 6500K daylight.... or anything between 5500 and 7,000K.
And the 3wpg measuring stick won't work with T5HO. T5HO is much more efficient at producing light, and therefore the wattage will pack a LOT more light-punch than the old T12 and T8 styles that the "wpg" rule was built upon. It gets even more inaccurate with LEDs.
But I think you're light will be fine as long as you're using CO2, esp. if you can raise it up a little.
