I searched the web for your insecticide, it appears to have some vegetable oil as a spreader/sticker if I'm reading correctly. I also noticed the ingredient you listed that appears to be a fungicide, but the pages I found said nothing about it.
I don't think I'd cut the leaves, the growth should straighten itself out when the weather allows.
This looks a lot like what I see at this time of year when the soil is cold, but the plants have been stimulated into growth by a mild rainy period. It appears that they're growing in quite a bit of shade, judging by the presence of moss growing in and around the bed. The pH can be fine, the trace elements can all be present, but if the soil is cold, the plants will grow, but will show signs of deficiency until the soil warms.
Definitely do the flashlight thing, and check a couple of times, once after dark, and again a couple of hours later. Also check on several successive nights. I've almost eliminated snails in areas of the yard by doing this diligently.
The two dormants in that bed sure look nice though, don't they? Even in my "too-mild-for-dormants" climate, I prefer them for this very reason. What's the plant furthest from the camera?
