Greetings,
I am new to this forum. Some background info... I am in a giant pumpkin growing contest with a few gardening friends, and this is my first attempt. We order Atlantic Giant seeds from a supplier, the largest seed being from a 1,100 pounder.

I live in the Pacific Northwest, so our season is a little shorter. I started the seeds indoors a few weeks ago (under compact flouros), and had great germination success in 6 days. But when one of them emerged, all along the edge of the first set of leaves was a yellow/brownish rot. I didn't think much of it, but now it seems to be spreading to the other leaves. I've already had to cut a few leaves off.

Please take a look at 3 images I've taken....

Any ideas? Will it just grow through this? Should I spray with something? Is this a pest? or disease?

Thanks in advance!

Nate, the more I look at that the more it looks like a bad chemical burn, kinda like a pesticide burn with it all blistered up. Have you been using any ferts, funcides, ect,?. Give some more info on what you been using on your plant.

Been thinking about it. Comments on the "general Discussion" board. They've been in the small pots too long so a nutrient deficiency is possible by now. However the necrotic spots on the leaves look like a major light or atmospheric condition...heat, sun, gas, etc.
