First off I apologize for the repeat post as this is already posted in the disease forum, but I'm in need of some quick input.

My 845 Bobier has developed an issue in the last 3 days and I'm not sure what it is. The first 5 leaves on the plant are showing rusty, chlorotic blemishes between the leaf veins. They aren't dry and the leaf texture is the same as a healthy leaf. Closer examination shows the blemishes are made up of tiny spots. The worst leaf is yellowing on the edges and has begun to curl in one spot. There was no evidence of this 3 days ago. All other leaves out to 8' appear fine. The hoophouse has been closed up for 3 days as we went from 85 to 50 degrees for 3 days with rain and drizzle.

Picture of the most severe leaf can be seen here:

Again, sorry for the repeat post but I'm a little disturbed.
Thank you for any help.

I am no expert but would guess that it is a sort of a burn. Did you use any sprays?
Since I had a virus disaster in 2003 I can qualify as virus expert though :-) so, you can relax... it does not look like a virus infection.

Absolutely nothing has been sprayed but seaweed in a freshly cleaned sprayer 7 days ago. I was just going out for my first fungicide application when I noticed this. Have drench fed with 20-20-20 once 2 weeks ago and applied Yucca extract and Bio Pak Plus(organic from Plant Health Care, Inc.)about 3 weeks ago.

Your leaf photo looks just like the leaf in the photo depecting "Boron Toxicity". I sent you a link.

Bill, check it out under a magnifying glass. We've just seen some form of powdery mildew showing up here. Takes the color out of the leave top and bottom. Best of luck, Duff

Just for the note: I was able to burn my plants with seaweed too...

That's weird looking...looks like a spray problem...maybe the combo of going back into the hoops after being out has something to do with it....let us know if there is a progression on the leaves that aren't currently affected..could be the ventilation/stillness of air movement has some effect on the plants respiration.

That is burn from the seaweed your spraying (the seaweed does not burn but the sun with the seaweed does). Don't laugh it has happened to me those spots eventualy dry out and become very brittle and holes will form. I have no idea why it happens but it does. We only drench with the seaweed now no overhead. Some people might disagree but it has happened. I dont know if it has to do with the age of the seaweed or what. I will try and dig out a pic from when this happened to me.

I feel that I had that once or twice and I narrowed it down to seaweed also. I don't know why, but I settled in on my backpack sprayer....seems I may have added seaweed first, then water and perhaps partially pumped inbetween resulting in the first squirts of spray being mostly seaweed. I wound'nt bet on it but thats what i eventually settled in on as a cause due to the spray injury being where I started spraying only.
