Why are they brown spots on my lettuce?

My cos, and oak leaf lettuce, which are about 16-25 cm high. are getting yellowsish edges and brown marks on some of leaves. It seems random but it is across all varieties. I dont spray, occassionaly liquid fertilize. Any help appreciated. Cheers Andrew

Dear Andrew,

It could be that your lettuce has bacterial leaf spot. This can happen when we have periods of cool wet weather during the winter months. Spot will appear on the leaves which tend to grow into each other and then the whole leaf will collapse. The best thing to do is to avoid overhead watering and make sure there is adequate drainage where the lettuce is planted.
