Spots, up-curling leaves, lightening

Hello,

The title pretty much says it all. This affliction spontaneously struck the two plants that had been my biggest, but fortunately it is only these two plants. They are about two weeks old.

You can see the spots in the first picture. They made me think bug, but I haven't been able to find one.

The color difference and the curling-up of the upper leaves were harder to photograph, but should be visible in the second pic. The lightening continued on one set of leaves until they dried up and I cut them off.

Does this indicate anything specific to anyone? My soil is dry except for at the bottom of the pot. I haven't watered in two days.

Thanks for your help

I'm using grow big, 12-7-7 but they haven't hardly had any yet. As soon as they were big enough I gave them a little tiny dose. A couple days later this started and I was concerned that this was nute burn so I haven't fed them any more. You think it may be a deficiency?

The temps are fine. ~65 at night ~80 during the day. Humidity is low, 25%. I guess it's time I pick up a pH meter.
 
over fert. try to raise that humidty as well. add some fine dolomite lime to soil to help buffer ph and provide mg and ca
 
until you get a ppm pen and are able to c how much your really feeding the plant you will just b guessing. if you get one feed with 400 ppm till 2 feet tall then switch to 800 ppm. feed feed water till the last 2 weeks then just water
