is it the lower fan leaves? Because i think you might have lock out becaues it looks like a combo of a few different ones. Nitrogen def, mag def, and K def and possible P def. Which usually means your medium/rez is too acidic/basic. More than likely acidic.
Try gettin some dolomite lime. If youre running hydro, id try to raise my ph a little.

Bud bro. Im in 3 gallon nursery pots running foxf. Ocean f. 4-1 perlite mix. Feeding every 3 days ,nutrients every other feeding .Now i have heard some questionable stuff about ffof but it gets me through veg. And for the most part holds a neutral ph through the grow (so i thought). Soil ph tested 6.6 in fourth week in veg with a soil test meter an kit. I have purchased Dolomite lime and Epson salt today. just dont want to try to treat a deficiency thats not there ya know. Heres a pic of another fan leaf. its started from the bottom to the upper middle part of the plant. Thanks bud bro

How much of each per gallon of water? I have the same thing in FFOF

Why do people always suggest nutrient lockout when it just might be a defeciency as a result of lack of food due to underfeeding?

What do you consider feeding as opposed to adding nutrients? To me they are the same.

Generally, newer growers go by the bottle directions on nutes which is often way to strong for the plant. This causes salt buildup and lock out usually, especially if you dont ph and are using alot of nutes which lower the ph. So if you dont ph, have slightly acidic tap water, and are using too many nutes lockout is usually the cause of most defs in plants.
Also, people often ph the nute solution too low. Somewhere around 5.5 when it should really be up around 7 since your medium will be/become more acidic over time and that messes with the nute solutions ph.
Most of the time, alot of problems can be avoided by adding some dolomite/hydrated lime to your soil mix before you plant.

Looks P def maybe bump your nutes

Potassium deficiency.

Hmmm K def eh? K usually gets locked out of high salinity mediums right? so If that were the problem a flush might help...bUt it looks more like sign of deficiency in N/P (and maybe some micros like ca/mg)...I'm just no seein K as the culprit....maybe a pic of the whole plant might change my mind tho...but what do I know

I was kinda thinkin mg, but that's why I wanted to see more of the plant to see how new growth looked, good call jon

What are you feeding? Your pH is fine (If you are testing the pH of the soil, and not the run-off) Depending on the concentration of the nutes, the every three day schedule could be nute burn. Otherwise I'd say it's a cal/mag issue. Mg def mimics a P def, too much Ca will lock out Mg. It's a delicate balance. If you rule out nute burn, then try Epsom Salts at 1 tsp per gal. The dead tissue will not regenerate, but all new growth from this point should be fine. I had it the first 2 grows. My dumbass used RO and distilled water.

that's what i think. are you using a good well balanced fertilizer with micros? as mentioned above, i'd also use some cal/mag. GL
