Started an indoor garden about 2 months ago with peas, cucumbers, squash, and peppers. I know some of these things don't necessarily grow easily indoors, but decided to try it anyway. Had a very fast germination rate; plants started sprouting within the first week or so, which is much earlier than they are supposed to usually.

Have had great success watching the plants grow under our lights. Many have started to flower.

Over the past few days, I've noticed a lot of sagging plants and curling leaves. Nothing is wilting to a crisp, but most of the plants still appear to be dying. Nothing in my routine of their care has changed; not the lighting, the watering, or the soil. Wondering what these "symptoms" mean: should I be watering more/less, or is it some other factor? Does anyone have any advice?
