Hi! My name is Cass and I'm new to gardening. I thought it would be easy, but it's a lot harder than I anticipated.
I noticed my beefsteak tomato plant had some yellowing leaves that eventually turned brown. At one point I had old and dying branches in the middle of the plant falling off, but the rest of it continued to grow. Today I have these yellowing, and then browning, leaves on my beefsteak. I've also included a picture of my cherry tomato plant's leaves which seem to have a similar issue, but to a smaller extent. I don't know what's up with my cucumber leaves.
I'm worried I have a fungus in my plants, in which case I think I have to give it up and try again next year. Strangely these two tomato plants sit beside two green pepper plants and my pepper plants appear unaffected. I admit that despite the heat (90+ degree temps in my neck of the US) I've only been watering everything at night. I realized my plants weren't getting enough water because one tomato had blossom-end rot. Today I started watering in the morning and at night. My plants get half a day of sun, half a day of shade. I bought a ph testing kit that will arrive Saturday.
If you have recommendations, please let me know! This is a lot harder than I thought. I feel like I should have tried a succulent first.
