I am running a six bulb t5 ho light fixture over a 24"x24"x24" 60 gallon cube with pressurized co2 is this overkill or not.
Bulbs are three 10,000K and three 6500K 24Watts per bulb
 
Well, You cant just use Wattage per gallon as not all light or fixtures are created equal. Alot will depend on the Ballast, the reflector and the wattage. But even more so PAR data. It also depends if you have the light setting directly on the tank or if its hung above the tank a specific amount of inches. With PAR data you need to know the distance between the top of your substrate to the bottom of your lights. Ten take a look at the chart below.. Chances are Id bet you have way to much light. But again depending on the quality of the light as well..

Yes, I dose potassium, Iron, flourish and flourish trace. Still new at this and trying to find my way. I do byweekl water changes to avoid algae.
 
Seems like overkill to me...I'd definitely make sure you are dosing N and P too, unless you are absolutely sure that the plants aren't being limited by those nutrients.

Look into dry fert dosing if you haven't already.

Do you have a drop checker or some other way of monitoring CO2 levels?
 
That seems like way way too much light! If you don't get algae you might be lucky. I would highly recommend cutting down lighting and using that chart listed above. You might want to dose NPK and CSM+B. And use pressurized co2.
