My sunflowers and my tomatoes are suffering from some kind of ailment. No one has been able to help me on the tomato disease forum so I'm hoping I could get an answer here.

My tomato: leaves are curling, have been drying up, turning yellow and eventually brown and crinkled. It seems to be moving from the bottom up and all four of my plants are suffering. Everyday keeps getting worse. They're in pots filled with potting soil and are watered when top of soil is dry. I fertilized with organic tomato fertilizer every 2-3 weeks.

My sunflowers: have tiny brown specks all over them and the tips turn from yellow to brown and eventually wilt and dye. I've lost at least 3 lower sets of leaves to this and I'm seeing the same symptoms on all the leaves. They haven't even bloomed yet and I'm hoping to save them.

This past week I used a light dish soap and water mixture thinking it was aphids or mites. But it seems to have made the symptoms progress even faster.

Pictures are attached below and your help is greatly appreciated.
