looks like magnesium deficiency...
make sure your ph isn't too high
have a fan softly blowing across the tops of your pots, constantly wet roots don't help with M uptake (unless you're in hydro of some form, of course)
too much Calcium or too much Potassium can also make it difficult for plants to absorb enough Mag

A picture of the entire plant would be helpful

Agreed
Looks like the post-child for a P deficiency

phos def. definitely. mite need a little more nitro but then again could just bee the phos. mke sure to stop it now before it turns into toxicity

I think alot of apparent nitrogen deficiencies are actually the result of extended p/k/b deficiencies. The leaves have a shelf life of about 2-3 months once they turn blue/gray/army man green. All the unmetabolized calnit brings da buggies and fucked up flavors.

Thanks all! I've added what was missing with fox farms liquid fertilizer. Most of the autos are in flower stage and were given higher P... the durban poison (photoperiod) was given a good all around fert that includes magnesium and Phosphate.
Two different types (auto and photo) are being grown at the same time. Loads of variables to control!
