Help! My tomato plants leaves are turning brown

[classyveggegal]

This is a Bonnie - black krim tomato plant. I've planted this tomato plant in an 18 gallon container about 4 weeks ago. Can you guys please assist me. It's currently the only plant in the container and it was planted with half mg and potting soil. So my issue with this plant is the leaves have started to turn brown on it's edges and it started at the bottom leaves and it's been creeping it's way to about the middle of the plant....it has been really rainy and pretty average 80-90 degree weather....any suggestions? Thanks for your help!

It is the start of fungal disease. Take off the lower leaves and mulch. Use an anti fungal spray to be proactive. It can be the start of early blight. Make sure you use good sanitation practices, bag and detroy all debris. Good air circulation around tomato plants, don't plant too closely or too close to a wall or solid object so air can circulate.
