Please help diagnose leaf yellowing

[mprasek]

This is my Early Girl, whom wintered over in a self watering container. We are in Houston Texas, and this container design (and container) has been used for 2 years without watering problems. ( The soil was renewed when the plant went semi-dormant in October.) The yellowing started 3 -4 days ago.

I have attached 2 pictures of the plant. I have a tendency to over think things, and would like others input.

I checked for bugs, spots and mites, worm poo,etc. Nothing found.

Thanks in advance,
Mike

Blight is my guess. I would get rid of all the dead and yellow leaves and spray it with Daconil.

Looks like nitrogen deficiency (bottom up yellowing; iron
deficiency starts top down), but it could also be molybdenum
or sulfur deficiency:

(Read the descriptions to see differences between nitrogen,
molybdenum, and sulfur deficiencies.)

I hate to say it but it looks like fusarium. Did you use a totally soil-less mix? Hopefully I'm just being paranoid since I see fusarium every year; but it does have that look about it.
