It might be fine. We have no way of knowing as we need a ton more info. What size tank? How high above the water are they mounted? What kinds of corals are you looking at growing? You really need to use a PAR meter in the water to test the PAR you are getting at various heights, then adjust your lights to match the PAR needed by your corals.
I have the same (2) AI Hydra 32's and had a similar profile setup like yours. Once we used a PAR meter, I bumped the settings up over 100% for the blues, etc but I plan to have a SPS dominant tank.

G’day mate I have 4 prime 16 over a rsr250 with mostly soft coral Iike a blue tank and I found that if you don’t use a lot of white 40-60% you will need a lot of blue to compensate so my lights are essentially like 2x32’s I have them mounted 10 inch and a 6 hour peak with all the blues maxed and 10% red green white. Everything is happy and growing
Depending on what corals you have you may have to bump up the intensities more, especially at that height. While I don't have the 32 I do have a pair of 26 at 9" off the water line at a max depth of only 14". My blues are hitting near 100% during peak hours.
