Is this the result of over watering?
I started my first container garden this year. The plants are currently located in the garage (where it is warm) and I am using compact flourescent 100 watt bright light bulbs. The seedlings were transplanted into large containers with many holes drilled in the base for drainage. The planting medium consist of leaf compost, composted manure and hummus, peat moss, vegetable garden soil from Miracle Gro, all-purpose sand, and top soil. I tested the PH level prior to planting and the range was from 6.0 - 6.8. I have watered them 1-2 times a week since being transplanted over the last 2-4 weeks. The beans and cukes were transplanted 3-4 weeks ago and the peppers over the last 1-2 weeks. They have been doing very well until yesterday when all of the sudden they started wilting and the leaves turning yellow. The cukes and beans have been hit the hardest. Any advice would be greatly appreciated. Thanks
