Peaking at my melons

Second time growing melons and so far so good. They grow so fast in the sun and in my carport is perfect. I just need to find a way to grow more than 4 on each plant. I planter Emir F1, same as last year. I have used the wire racks from the shelving system and canes and wires to support the plants. At first it looked like i was going to have 20 melons per plant but most of the baby melons dont carry on growing. Maybe the plant cant manage more than they do.AND, no mildew this year, Yay lol
