I normally would never reccommend this but you might want to consider it.......alright, get yourself some type of sprayer, put it on the finest mist option it has, fill the container w/ph'd water, now take a very small bit of fert and put it in, along w/a drop of liquid dish soap. make sure you dont get any water on the lights, in fact you should keep them off for a hour or 2 so any water still on the leaves doesnt magnify light and cook/burn them. spray the leaves, especially the bottoms of them, in an hour or 2 go back and with clean water spray down the plant again. I set mine on its side sort of so i can spray the bottoms of the leaves most thouroughly and the water running off the leaves doesnt go into the soil.
