I would say, no... Unless it is a very early case.

But its not spreading quick. It seems the plant is casually killing the fan leaves. I have two other plants whom are about 2 weeks behind in flowering than the pics above and even they are killing off fan leaves....advice please!!!!!!

Oh yeah....see my green leaves dont have ANY brown spots ONLY the yellowing ones get brown spots on them....the green ones around them are spotless.

yellowing of the fan leaves is normal in flowering but the burn must be some type of deficiency. To me it looks like your plant isnt getting enough manganese. manganese is best absorbed at 5.5-6.5 but isnt locked out of the soil till 5.0 ph. although this may not be the problem the best way to find out is to test your soil ph. What week of flowering is your plant at right now?

I think if it was leaf spot it wouldn't be restricted to the fan leaves like it appears to be. If this is not normal yellowing for flowering time (seems not) I would say it is Magnesium deficiency, N deficiency, or low pH.

Having plants that are deficient in manganese can turn the young leaves into spotted (mottled) yellow and or brown areas on young leaves. Dead (Necrotic) yellow spots form on top leaves, while the lower older leaves will or may have gray specks and or spots. Symptoms can include yellowing of leaves while the leaf veins can stay green. Can also produce a chequered effect. As the plant gets newer growths the plant will seem to grow away from the problem, that’s why the younger leaves may be unaffected.

I have noticed on some of my plant's that i got under control and even one's that didn't get it, that the older fan leaves which are being used up in the plants life cycle are prone to developing it before they fall off. But if the plant has made it thus far she is fine.

Very interesting, since I have noticed the same exact thing. I was starting to wonder if it wasn't leaf spot but something with my pH, but now I am reassured... Thank you!
