it does seem counterintuitive as an ample amount of light is normally needed for variegation. however there are other factors - of the traditional three - food, light and water, food would then be your next choice. it is possible you are not supplying it with the mix of fertilizer needed for strong pad production. if you're busy feeding heavy for blooms, you might not be getting enough nitrogen for good pads.
heat is sometimes a factor and hardies tend to like slightly cooler weather than what tropicals will thrive in. at a certain point getting too hot can be detrimental - especially to pads. at least that is what various people have said - i wouldn't know by experience as we never get that kind of heat here.
and yes, your not policing your pads could be a factor as well. any energy that a plant sends to maintain a dying pad is sucking it away from new growth. how well a pad gets started will effect the rest of its life. removing dying parts from any plant is a good idea for the healthiest plant possible.
lastly, anytime you move a plant it is possible for it to go into a mild shock or worse. it can take a while to adjust if the environments are very different.
if it was doing good before i would just move it back or wait it out to see if it adjusts. if you really want to get rid of it, offer it for trade or give it away here. i would gladly make room for another arc and i'm sure many newer ponders would love to have it for its unique pads. i mean, if you decide to toss it, make sure somebody catches it, right?
