Oh man, that sucks. It looks like the new growth is dying. Have you done anything differently since before it started like add any supplements or boosters to your base nutrients? Or what have you been feeding with?

For a veg nute miracle grow isn't that bad. People like @hotrodharley have mentioned using it without problems, and when I had nothing else I used it, no deficiencies. This might help

Harley also commented recently on another thread where iron deficiency was a possibility, and the other poster mentioned a spray, I think it was in the marijuana plant problems section.

How would flushing help? All you'll do is wash out any nutrients in the soil, and if you don't have any nutes in the water you use you'll just cause other problems. I believe it's called hypotonic stress? Or osmotic stress? Definitely osmotic stress. I usually don't bother with ph as I grow in soil, but do you have any info on the general ph of your rootzone?
Pruning the dead growth is fine, but I would hold off on pruning the yellowish stuff until you have new green growth. The parts of the leaves that are still green are still performing photosynthesis and feeding your plant.

I’ve grown a lot with MG. Works great in veg. A bit rich in nitrogen for the best flower but any tomato food will handle that.

Have you switched back to the low dose miracle grow? It sounded like that was working for you before. I've never dealt with an iron deficiency, so I'm kinda shooting in the dark here. Was there a stressor, something happen or change other than slightly increasing the mg?

Lots of shit storms .. bad weather. I'm eaitig another day to fully dry the soil then gonna feed the low dose mg . Basically all I can do. I also pulled my WW out her pot to check the roots..they look healthy a little bound but I've never had an issue like this from root bound. So I threw 4inches of 3 way mix soil to the bottom and replanted it. I have no bigger pots I would repotted altogether. Playing the waiting game. Still seeing spot of death in the affected areas. I'm mainly watching other new growth spots to see if they develop or not.
Edit- now I'm wishing I took a pic of the root zone when I had it out the pot. Oh well.
And one more thought to throw out there. I have these affected ones next to NOT on (lol) a soy field. The farmer is my landlord and he sprayed the crop right before my plants went south. Is there a possibility his spray was herbicidal or something? I'd think my plants would be dead though. I see clearly other weeds in the field dying..thats why im wondering.

That is a definite possibility. If they didn't take a direct hit it could have damaged them. An iron deficiency, if I've understood what I've read correctly can be a reaction to stress.

Soy. Do you know if it's Monsanto soy? Farmers around here put signs up saying what seeds they're planting. I see them every time I drive to my sister's place. Even if they're not Monsanto they could be GMO, and resistant to whatever hericide he might have sprayed. Even if he sprayed fertilizer, it could have caused a lockout. Potassium can cause an iron lockout in high enough doses. It's one of the things I was worried about when I was researching potassium bicarbonate for mold/powdery mildew control.

Update - I took care of the affected plants as best as I could and it took about two weeks of clenching my teeth. All the new growth died so I cut tje dried out dead parts. Just kept watching them and feeding keeping in mind there's still plenty of green leaves performing photo synthesis. One day I noticed new growth. It was coming around. And as luck would have it I got about a week of solid new growth before flower kicked in. Enough to bring it back to life..
