Sickly Looking Plants...

[bigducky79]

My plants are about 5 1/2 weeks old growing in a closet setup. I have proper ventilation, a fan blowing to circulate and keep it mildly temperate, and enough lighting to suite the plants until I receive my prev. ordered HPS light that will arrive shortly. I am growing hydro using the wick system but my plants are all of this characteristic: they are growing full and tall except for the lower leaf sets which are sometimes brown, yellow, and curling downward.
I have nutes added to the water and at the right amount. Please someone help me to get my plants looking ENTIRELY healthy and not just the top sets of leaves...
