Squash

[RenettaHogan]

I planted squash in my ebb and flow system. They're beautiful plants with huge leaves and a ton of flowering branches. My problem is that after the flowering stage, I get nothing. The branch starts to wither and die. My TDS is anywhere from 1640 to 1740. I keep the PH in the range of 5.5-6.1 I also have cumcumbers, tomatoes, green beans and green chili. I'm just wondering if my TDS is not too high for the squash. I change out the nutrient solution every two weeks and use distilled water. I'm not sure how to get those flowering plants to produce something. Any recommendations?
