Hello everyone, books and investigation online is hard when it comes to disease as so many seem so similar. I’m growling my veggies inside to get a head start on the MO climate and I’m noticing my verity of different tomato’s some are showing signs of disease in what I’m guessing is their vegetative state. I’m not sure If having different varieties grown so close together is my downfall. Some were showing yellow lower leaves so I let them dry out some I had though possible overwatering. After that experiment no dice it was getting worse so I put the water back to them, maybe under watered. Well now the black spots are showing up and leaves are dying so I need to get a hold on this. I am giving them the light 16hours a day. Is there a size they light should be cut back or as long as they get 8 hours of dark they should be fine? Anyone have a guess at what I’m dealing with. New organic potting soil as well. Old pods though maybe something left in them? I’ve seen some talk of bleach bathing growing pods between seasons. Thanks for the help.
