My first time to attempt to grow, anything really. Most of my Tomato plants leaves are yellowing and withering / shriving. I'm not sure why, maybe too much water? Or too much sun. They get sun all day long. And it's still cool here in TX. Highs are about 70. Growth medium is 1.5 part bag compost (home depot), 1 part moonure, and 1 part pearlite. I wanted to make 1 part everything plus 1 part coir, but It didn't come in before the plants out grew the starter and I had to trans plant.
The image did not work in the preview. Here is the link https://imgur.com/a/uWr3h Also included is a pic of a squash plant that is yellowing / dying on the outside of the leaf. Oh, I had added a few pellets of miracle grow slow release / pot when I transplanted them a few weeks ago. But they started acting weird a few days after I started keeping them out side all the time this week.
