So I'm doing some DWC tomatoes and peppers. My peppers seem to be very robust and tolerate the conditions well. The tomatoes are struggling. Some with Yellowing leaves. I've included pics below. My nutes strength is about 800-1100 ppm. I've included some pics below of three different plants. None of these are currently on active air pumps. Also included pic of my nutes solution strength. Any thoughts? Suggestions. I don't know why my peppers love my conditions, but these tomatoes are so picky. Just for varieties, I've got Beefsteak, silver fire tree and Bucks County. Thanks for any help.
