Tomato plant leaves curling, wilting, and turning yellow
I'm growing a "Better Boy" tomato plant indoors. I used Miracle-Gro Potting Soil. The plant is beginning to fruit, but in the last few weeks, almost all the leaves have started drying up, curling inwards, and turning yellow.
I'm watering the plant via a pair of irrigation spikes: http://www.amazon.com/gp/product/B002558KJQ/ref=oh_details_o00_s01_i00. So the plant should be getting enough water. I've also tried watering the plant more, in the hopes that it just wasn't getting enough water, but that doesn't seem to be working either.
Any idea what might be going on?
Thanks so much!
