Ok...so it comes and goes... does it happen close to watering? Either wilted before watering or wilting right after being watered? If so try to find a good wet/dry balance. If it's after watering then we want to consider that the soil needs to dry faster(maybe more aeration like perlite or pumice), it may be having root struggles(rot/lack of oxygen) , otherwise sometimes a root bound plant can wilt when it needs transplanted.
You might want to also bring your light hours down from the 24, i think all living things benefit sleep and i usually think 20/4 or 18/6 is the best way to keep the plant calm and happy.
