get some clear plastic cups and place upside down over your clones.. Buy large enough ones so your leaves aren't all pushed along the sides.. it will save you some $$ on a fogger and will raise your humidity.. 2L bottles may work for you too..
Also how much drainage do your pots have? (holes in the bottoms) Ive noticed a nice tray under your pots - make sure after you feed, the bottoms of your pots are not sitting in the over flow water.. this will decrease the soils ability to drain and add O2 to the roots..
