I've got these four chronic plants, all about 4 weeks old. They all seem to be doing fine, but today on one of the plants I noticed the new leaves growing in, were coming in a lime green color. Could this be the start to a magnesium sulfate deficiency (all leaves are perky and the older leaves are a normal color, but the oldest ones seem to be getting smaller) or simply just light bleaching? (I'm using 8 26 watt CFLs wired through a homemade Mylar fixture, vegging space is 0.5'x2'x0.5', soil is an organic mix of composite bark and peat moss, 50% soil 50% perlite, 20-20-20 mix of micro nutrients at 1/4 strength added to watering once a week).
