They kinda do look thirsty. Are those 5 gal pots? I just watered all my girls tonight(5 gal fiber pots), last water was 4 days ago. I gave them all about 1 gallon of water, till run-off.(wanted to check Ph out anyway) i wont bother checking them for another three days or so. Also..some strains are really picky..nutes,water,light, its hard to keep everybody happy sometimes.
