To much water?

Depends when was it taken if this was taken when the lights have just gone on then no its just the plant opening up its stomatas to collect moisture from the air or anything else you give it thats why you should use foliar sprays just before the lights go off. If this is while the lights are on though yes this is defo an over water :) Nothing that a few days left wont fix though to stop this happening in the future I would advise only watering around the base of the plant and not saturating the whole medium she is not that large shes does not need much at this stage though I will say other than the slight overwatering that is one happy healthy plant well done sir !
