I have a dilemma. All of my indoor plants (pepper, tomato)
have yellow and brown spots on the leaves and they are wilting. They are only a about 1 month old. I have held off fertilizing since the potting mix was very rich.
I have a fan blowing on them and lights going about 16 hrs per day. They don't seem to need water only about once per week. Could the problem be that they are too wet or is 1 watering per week normal. Could it be something else? Thanks
