I'm getting necrotic leaves and spots on my plants. I'm afraid that I won't have a harvest if this continues. Please help!!

Looks like over fert or wrong kind of ferts. Heck, maybe even underfert. More info needed.

Did it rain or have you watered recently? Could be sun spots from sediment build up on the leaves. Not usually the case outside but maybe near a city or industrial area with acidic rain.

I have something like this going on right now. I just flushed my babies and one of 'em got some spots on a leaf. Looks like potassium deficiency to me, and it might be the case with you, but I couldn't say for sure without more info.

LOL, that is a great avatar! I watered them and the next day it rained, and the day after that, and the day after that. So yeah, it will be September before they are thirsty again. I gave them a little N a few weeks ago.

Well I decided to either kill them or cure them. So I added the full dose plus a little extra, of all purpose fertilizer, a shot of 5-1-1 "worm poop" fertilizer, some Epsom salts, and a little pH down. Mixed all that in 2 gallon watering containers and gave them a good soaking. That was a few days ago and they are starting to come back. So I guess the plants had just taken up all the nutes - or at least the N, and needed more. Whatever it needed I seem to have given it now.
