I have had squash, zucchini, and cantaloupe seedlings growing for about 4 - 6 weeks in 3 inch net cups. The bottom leaves are turning yellow / brown. The plants look a bit yellowish rather than bright green. They are bottom watered about every other day sometimes daily when needed.. I am using 5000 K lights for 16 hours per day. The soil is fertilized. Plants are continuing to grow and producing flowers. I need suggestions as to how to solve this.
I will be planting them outside in about 2 - 3 weeks. Should I remove the blossoms since they will still be inside for a while yet?
