i would keep the humidity a little higher around 50 percent but if your not doing anything to keep it down and thats just what its naturally at dont worry about it much it definitely isnt too high...i think a gallon each is alot because most will come through the bottom if you dont do it slow and spread it around not just one spot but if that is what you like to do no problem with it so long as you dont water too often...lol ya the buds are in the right spot and i dont like to prune anything as far as fan leaves unless its realllllly in the way of a giant bud and most of the time i still just move all the leaves blocking buds everytime i would check on them so that they are held down and out of the way by a branch or a bud or something instead of clipping, remember the leaves are big solar panels without them your plant will not make enough energy to reach its full potential..what i will strongly suggest you do though is look at all the branches under the top canopy and any branch that is fully shaded with no possibility of bringing to a sunny spot gets cut off with a clean razorblade (unless their is still a good nug on it) most of these branches will be stunted and smaller anyway. you can continue to do this for the next week or two if you only want to cut branches that your sure of and then later see another branch that isnt going to produce. trust me the energy wasted on these branches all combined will yield you a whopping gram or two a plant lol your way better off diverting that energy to real buds!
