cantaloupes not maturing

ok so my cantaloupe are not filling out .. they have lil buds starting but none are filling out to be an actual loupe .. they never get over 2-3 inches before shriveling up and dies..
my soil is topsoil and compost with perlite ..no nutrients added due to the compost.. my tomatoes are just a rollin.. there in a 5'x4' raised box about 2' deep.. just 2 cherry tomato plants and 2-3 cantaloupe vines.. i have about 10 lil baby cantaloupe but they never get any bigger.. +rep for help.. love me some fresh loupes

When melons don't get enough water they stop growing. Don't over-water them or the vines will collapse, but continue to keep them well watered and remember that the larger they get, the more water they will need. Allow the top 1 to 2 inches of soil to dry out between waterings.
Make sure you're using the right fertilizer. Use one with 4 parts phosphorus to 1 part nitrogen to promote larger vines and better fruiting. Ideally, this would have been added to the soil at planting time. Adding additional nitrogen after 1 month and again 2 months after planting will keep your vines growing.

thank you, we have had a lot of rain in the last 2 months and i have yet had to water them but i guess i'll pay more attention to them.. thanks again..
