As the title states, I have three legumes in my high tunnel that are all showing poor new leaf growth. The leaves are a little spotty, but mostly look a bit curled, roughened, and leathery. We had an herbicide drift issue several weeks ago that hit my tomatoes, but this is a newer issue. I also just had a HUGE thrip issue this week on the tomatoes, but I can't see any on the beans.

Is this an environmental stress? Disease? Nutrient issue? I haven't run into this before.

Happy to provide more info as needed to narrow this down.

I have a greenhouse in northern Indiana, USA zone 6B. I had a bad glyphpsaye drift even from the field next to my property that did some damage to my tomatoes, so I have been dealing with the twisted leaves and poor growth since them, mostly removing the worst new growth and trying to get new branches to take over as leaders.

I realized this morning that the new growth is getting worse again, and took a very close look to notice a TON of thrips on most of the tomatoes. They haven't infested anything else nearby as far as I can tell, but the tomatoes seem pretty bad. Probably as a result of the previous herbicide stress. I'm thinking that these are causing further meristem damage as the new leaves try to grow in.

Could someone provide any insight on how to deal with this moving forward? I these poor plants have already been through a lot and I haven't even started harvesting yet.

This is obviously anecdotal, but:

I have a had a scrap of greenhouse plastic down on one of my garden rows for a week or so, and noticed that three blister beetles had fallen into some water that had pooled on it. I didn't make a special note of it, but I believe I saw all three on Saturday, maybe in the afternoon, and it is now Monday evening.

All three were flipped over and had sunken to the bottom of the puddle, so I assumed they had drowned quickly. I was adjusting the plastic today and decided to dump out that puddle. As soon as they hit the soil, they all moved their legs, flipped over, and crawled away.

For what it's worth, a crane fly and all manner of tiny flies and other insects had also fallen in and were all bloated and dead. I am almost certain the crane fly was not there when I noticed the beetles, and that it fell in sometime today. I've never seen a terrestrial insect deal with being submerged for so long without much issue.

Anyways, there's always a chance I am misremembering the timeline, but I would bet bottom dollar that they were fully submerged and upside down for at LEAST 36 hours or longer. Was just curious if anyone had info on this sort of thing, and I don't really have anyone else to ask. Is this something they are known to do?
