did you foliar feed? it looks like they've been burned...
1400 ppm is 2.8 EC, that's a SHITLOAD of nutes unless they're fully grown and at peak flower

they have never been foliar fed and they are about 3 weeks from harvest so i think 1400 is ok. it is a recirculating dwc and only some of the plants are showing this yellowing so i am stumped.

First off, it looks to me like you are doing everything right. i'm stumped as to what your problem is specifically. BUT it looks to me like a pathogen, not a nute deficiency, or bugs.

Change out your nute solution ASAP, clean tank, and flush plants with a H2O2 solution (1-3 mL per gallon). Dump this solution and refill tank with new nutrients. You could raise the nute solution temp, however, this is probably not the problem. I've successfully grown hydro crops with 57 degree temps.

Buy a HEPA filter, an activated charcoal filter, and a UV light. You might not be able to stop this problem on this crop, but hopefully these devices will prevent future problems.

good luck!

BOSCO...my plants were giving me the same (deficiency.).its pluaged me for 7 months but i finally figured what it was and what i did corrected it..so heres some advice that help my babies..hope it helps yours..1st) BUZZ was right you have to keep the water temp between 65-68..2nd) regular flushes are a must..what i use is clearx by bionicare..it saves on water and and its very gentle..little goes a long way..3)after my flush i adjust the PH to 5.5-5.8 then start with a weak nut. solution to get my babies back into the swing of things..if i get to nut happy i find i have to repeat step1 and2 all over again because they need an adjustment period..say 2 feedings 1/2 strenght..then their ready for their regular feedings..it took alot of trail and error but this worked perfect..all the new growth never showed signs of what i call salt/PH burn with this method..hope this helped..feel free to ask any more ?s if its still giving you a hassle ASARU
