How do I maintain regular soil moisture in humid weather? I can't remember the kinds of bugs that I was seeing on my red pepper and tomato plants, but I saw them time to time and I bought insecticide for that reason. So then I watered it morning and afternoon because the soil was so dry, so you're probably right on the too wet and dry cycles. I can admit that I was inconsistent in the water because early in the season, I started out with watering once a day in the afternoon, and then as it got hotter I was watering in the mornings before I went to work because I would get home around 5 p.m and they were shriveled up by that point from so much hot sun. The affected leaves wasn't totally covered with the brown spots, but it was brown streaks down the centre of the leaves and then out towards the outside of the leaves with some rings, and lots of yellowing leaves. Sorry I took long to reply I unfortunately didn't think about taking a picture at the time, I just threw them in the trash once I pruned them off Now I wish I did take a picture. Why would you want to treat any of that with insecticide? You have a condition caused by variations in soil moisture and perhaps a fungal disease. Cultivating too close to the roots and damaging them or nights that are too cold when the fruit is being set can also cause it. When it's been moist enough and the plant is growing rapidly and then it suddenly dries out, the calcium transport channels get shut down. You don't want it soggy or sitting in water, but the BER isn't about over-watering per se it is about too much wet and dry cycles. Whether or not a particular tomato is going to have BER is determined when the fruit is set. It is all about inconsistent watering and going through periods of drought stress. Some people swear by all the calcium stuff for blossom end rot, but really it almost never has to do with a lack of calcium in the soil. How about a couple pictures of the plants/ leaves for what makes you think you also have early blight.
