problems w/ pics

Hey I got some problems with my plants that I am unsure of the roots. Could be an N deficiency, fert burn, ph problem, or something else I'm not really sure. I feed with a mixture of shultz 10-15-10 and VF11 for trace elements, and foliar feed them with a weak VF11 solution.

thanks for any help

looks a lil hot maybe and maybe a little bit to much of your nutrients but you are fine if it doesnt get any worse anyways....

could be a heat issue but the little therm I have isn't totally reliable. usually I leave it on the floor or on top of the dirt in a pot and its usually around 70, but it has spiked too high before for periods of time, I'm thinking it might be a cold issue for the last 2 pics because last night I forgot to turn heat on and its in the cold corner, but the ballast works pretty well I don't think it dropped below 65

Don't look bad at all, good color, good shape, good growth. What is VF11?

VF11 is a fertilizer that has lots of trace elements that are good for cannabis. this includes iron, manganese, copper, zing, boron, molybdenum, calcium, and magnesium. It works great as a foliar spray.

oh yah the color doesn't look as bad as it actually is. The yellowing smaller leaf is actually browning on the side.
probably because of the lighting (metal halide) being heavy in blue/white
