Plants still alive ... for now

Today I was supposed to water my plants, but yesterday we had a pretty decent rainfall so they didn't need it. Instead I took care of a couple other tasks. I picked off a couple of dead leaves and dumped the water from the bottom trays (important for preventing root rot). I had also noticed that when they were watered or when there was wind or rain, some of my plants, particularly the kale, would sort of tip over and that they were starting to grow at odd angles. So I grabbed my leftover potting soil and my trowel and scooped three to four extra shovels of dirt into the pots of the plants that seemed unstable. I didn't water them after, like I would if I were potting them, because I didn't want to flood them out after the rain. Instead I just patted the dirt down, and I'll have to wait until the next watering to see if it worked.

I'm a little worried about some of my plants. A couple have leaves that look sort of dry and damaged. My first thought was too much sun, but they are already North-facing and shaded for most of the day.

What is wrong with you, plant?

 A few others look sort of droopy and I'm not sure why. A Google search tells me that can be caused by too much sun (but again, they are already in a shady spot), too much heat (but it has been pleasantly cool/mild lately), too much cold (but we haven't had a freeze yet) or not enough water (but it rained yesterday). I'm pretty much at a loss. Maybe next time I water I'll add fertilizer, but in the meantime I'm just hoping for the best. If they start doing worse I'll try getting in contact with someone from the county extension office.
