Aloha 🌋looks as if your cuc’s hadn’t pollinated properly. Remove them immediately when you see that or let one that’s yellow to save seeds. You also shorten the life expectancy of the plant when you stress them with fruit that’s struggling it’s self. Plant bee attracting flowers around your plants to attract more bees maybe. I also remove the one big leaf from around flower clusters to help the bees fly in and out more freely. Feed your plants with ready available teas or ready available liquid fertilizer. Cuc’s are heavy consumers.
Container growing ;especially, in plastics are not an easy way to grow. Soil can get to hot and hold to much water if there’s not enough proper ventilation or irrigation which in turn causes soil born troubles. Mulch decomposition if not proper will also cause soil to become to hot when the decomposition process is in process and containers don’t allow enough airflow to cool the soil. Bottom holes isn’t enough. You also need holes on the sides. That will help your soil be healthy. I hate to confess it but container growing is not easy;especial, if you live in a hot or rainy area. I do raised bed, mounding and level farming and so many of the crops thrive outside on the ground much better than a container. It’s how God intended plants to grow, free like people. But as everything else, man wants to control the natural ways and cycles things are done and rule over even growing food crops. That’s why when we find a come again seed plant thriving without our assistant we are puzzled. Plant work through their struggles without us. I pray over every seed and plant we put in the soil.
“Lord here is a miracle as I hold a seed. You’ve blessed our farm with this gift which hold so much potential. Your seed from above. I place it in the soil as if in Your hands. Tilled the ground then sewed it in Your rich soil, water and feed good nutrients and speak Your Living Word over it daily. I always stand in awe when that tiny seed packed full of energy pushes its little🌱 self through the soil and soon becomes a thriving source of food.”
Don’t let this discourage you. Always start over and there are many well informed folks here to help support your success.
God bless
