Why are my cucumber and cantaloupe leaves spotted?
This is my first experience of having a raised bed garden. I chose a cinder block garden and am trying my best to make it an organic endeavor. I made my own soil mix consisting of compost/manure, organic gardening soil, peat moss, and organic soil conditioner.
In one of my garden beds, I planted lemon cucumbers and cantaloupes from seed. Everything had been going well. The cucumbers hadn't produced any flowers yet but they were growing and climbing their trellis. The cantaloupe had developed blooms. Two days after I made this wonderful observation, I watched my bed become destroyed. I've researched and I can't figure out what the problem is.
This was my cleanest bed. Butterflies and bees visited frequently. I have marigolds planted around the bed. I used Epsom salt once because I read that the soil could be missing a nutrient that was turning the leaves yellow and that it would boost fruit production. I don't know what else to do. Even if I lose this crop, I still want to know what is wrong before I plant anything else in there for the fall.
