Cantaloupe leaf disease... HELP! (w/ pics)

[BMehalso]

Hello!

I'm new to the forum and this is also my first year gardening. It's been going well, not great... but well. I'm learning a lot. In my pursuit of learning more I need some help. I have two cantaloupe plants (Hale's best jumbo, Hearts of Gold) and their leaves are starting to yellow and look infected with something. It's spreading quickly as well and I'm not sure how to handle it (prune infected leaves, let it go, apply fertilizer, etc.) It's the older leaves that seem to be getting infected first. I have about 5 tennis ball sized cantaloupes growing so I'd like to figure it out before I lose the harvest. They are in containers and the mix is 1/3 compost 1/3 vermiculite and 1/3 coco coir. I've fertilized the plants once this year with Trifecta+.

Any help is appreciated. Thanks!

I don't think it's a disease. It is a watering issue as shown by the upturned leaves. It could be either too much water or not enough. Only water when the leaves are slightly drooping in the early AM.

I feed them about a gallon of water per plant, once a week. Unless is rains, then I cut my watering back slightly depending on how much it rains. I use water from my rain barrels. Should I water more?

They're in 30 gallon fabric containers if that helps any.

I don't think that's enough water. How hot and windy is it?

It's been very hot recently. Low to mid 90s during the day. Maybe I'll water them tomorrow morning with 4-5 gallons a piece.

If you do don't water again for about a week.

They are flowering? Have you fed them lately or just when you planted?
