Remove the dome asap, cannabis does not need extra high humidity, it is not a rain forest plant! She needs good air to grow properly, leaving her under a dome can lead to fungal problems, stretching and the chance of getting cooked. Spraying cannabis plants with water is not beneficial. Cannabis is a tough, hardy plant that can cope with much adversity, it is not a dainty, delicate princess perfect type of plant. Again, this notion of high humidity is an old hippy myth from the 1960s when no one knew much about cannabis and people thought it came from the tropical jungles of Vietnam. Most Indicas come from arid semi desert regions like Afghanistan, Morrocco, Pakistan and most Sativas come from low land dry zones in equatorial countries and is grown exclusively in the "dry season. Big light + humidity dome + spritzing = sweat lodge. This is probably the worst environment for healthy development. The big light at 24 inches will be fine if you remove the sweat lodge.
