oh ok, i was saying it looks like iron because its mostly on the young leaves and iron is immobile and potassium is mobile. .

Potassium deficiency? Neb is supposed to be a very heavy drinker and I was backing off the nutes because didn't know that until recently and I thought I might be burning them. I have them dropped down to 950-1000 PPMs (.7 Conversion factor I think). Should I bump them back up to 1100 or so? If nobody tells me this is definitely a deficiency I'm going to wait until my next crop goes in and keep one res at 950-1000 and bump the other one up to 1100-1200 and see which one responds better.

nahh the burnt tips along withh the scorching is def nute burn....give them a flush(or plain water if in hydro.dwc) for a day or 2 and then resume...

Okay, great, glad I asked. I'm at around 950 now. What should I shoot for after the flush? 800 or so?

I'm using well water, it's 250 PPM out of the tap. And I'm running ebb and flow in hydroton/red lava rock mix.
