I question your alk and Ph numbers. Typically with alk at 10 i would expect your PH to be much higher. Alkalinity at 10 is on the high side. Zero nitrates are a problem. Nitrates are a food source for anemones. Anemone farmers feed them nitrates. They love high nitrates. In my experiance they will thrive with nitrates as high as 120. Othere corals may not do so well with nitrates that high though. There are threads here on increasing nitrates. I almost never feed my anemones directly.
I suspect lighting is also part of your issue. Anemones love a lot of light. Generally it is hard to give them too much light. White and blue both add up to provide the amount of light they need. How many hours you have your lights on each day is also important. Your trying to mimic the sun as best you can with artificial lighting. You want to make changes gradually especially to your lighting. I would put your lighing back to what it was before and slowly increase the blue 10% and possibly the white 5% every couple days. You don't have to go by a specific AB program if you prefer more white in your tank. Depending on how many hours a day your running your lights you may want to increase how long they are on as well. My tank is mostly white. I don’t like the blue look as it is not natural and my fish look like crap under blues. I do have more blue in the mornings and evenings.
