| Hello all, Was wondering if anyone is familiar with these types of spots/marks on lettuce leaves. I'm growing Queensland Lettuce, and it's been raining a lot in muggy Miami. I'm very familiar with leafminers, but these don't look like trails...they're more like little splotches, yellow or light green in appearance. It's extremely consistent, on all my lettuce and even arugula. I can't seem to figure out if it's insect or fungus related. More importantly, are my leaves still edible? Any help would be greatly appreciated. Aside from this, the leaves seem happy and are growing nicely. Thanks, |

| Thanks @Peter1142 for the response. I didn't think it was related to sun stress due to the fact it has been raining for weeks. But it's totally possible, B/C when it is sunny.....boy, is it sunny. Very hot and humid over here. I did some additional research and found some photos of Thrip damage that looks like this. So it's one or the other I guess. I suppose in either case, the leaves are okay to eat? I hope so, my harvest is pretty modest. Thanks! |

| Well I'm not an authority on the matter, but my romaine had something similar going on, and you could see it was only on the outer leaves exposed to the sun in summer, the inner ones were normal. And it didn't happen to the lettuce that matured earlier. I ate them all and lived to tell about it ;) I wouldn't worry about it, just wash it well of course. You can't expect blemish free leaf crops.... |
