So this week my lettuce is growing to be so big, but my tomato plants are still looking like they are going to die. They keep growing big and green, but the leaves will then start to yellow. I looked on the internet to see if anything could help me figure out why my tomato plants are turning yellow and I think it's because of some fungus that they picked up. I noticed that Luke hasn't used the new soil that Mr. Hardin bought for us to transplant and his tomato plants are doing fine, but my tomato plants are planted in the new soil and keep getting yellow. Maybe the tomato plants aren't getting enough nutrients from the soil, or they have some kind of fungus. I'm still not sure what is wrong but hopefully they will improve soon.
