My AG pumpkin is in a SWC, and was doing well. I did have a few small splits in the vine, which I repaired, but the leaves are browning on the edges, eventually moving into the leaf, with the entire leaf and then stem eventually wilting. It is doing this on vines that do not have a split, so I don't think it's from that. Our temps have been approaching 100 for over a week, almost 2 now. I may not have been filling the reservoir with enough water...would that do it?

I am filling the reservoir with diluted fertilizer, about 2 x's/wk, though the last 2 times I filled it, which is daily at this point, I did not. Another thought was too much fert, but it was really dilute...1/3 strength.

Here's some pics...thanks for your help!
