Nute Deficiency or Light Bleaching

[letsgetalongbrd]

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).

Doesn't look like light bleaching. For me, light bleaching happens very fast and usually not on younger leaves. It looks like it's your temps. depending on how hot your getting. Also, if you have a dark cycle and your temps drop and come back up in the light cycle it will cause your younger leaves to be noticeably lighter.
