Hello,

I'm a first-time gardener, and I've got nearly all of my zucchini
rotting at the tips (see photos).

I've searched for info and come across two possible causes: calcium
deficiency or too much moisture. I haven't done a soil test, so I'm not
sure about the calcium. I'm using a drip system, but I also do overhead
watering quite a bit - perhaps that is the problem? If I did supplement
the soil, is there an organic or relatively natural method?

Thanks!
