seeds Issue with seedling

     Prune off all the affected tissue. That pretty much means removing every meristem (since these herbicides localize to new growth). It's a hard pill to swallow, but it needs to be done. As soon as you do this, the vast majority of the chemical will be out of your plants' systems and the next flush of leaves should be back to normal. 
     It sucks, yes. But it could be worse. When this happened to me last year, it was already June. Needless to say, my plants podded up late! 
     I hope all works out well for your grow. Keep track of which plants were affected/pruned. Pay attention to any residual effects once new growth begins. And be sure to post updates in this thread. Pics of pruned plants, pics of new growth, pics of healthy plants… Hopefully this can be used as a case study in how to handle herbicide overspray and save people time and money (on miticide) in the future. Hell, maybe OKGrowin could use this info in a troubleshooting section in his FAQ he's been workin' on.
     Good luck!
 
Well I think I have gotten rid of the mites. I used a combo of Malathion, and Bifenthrin a few days past each other. After this was done I watered the plants extensively the next day. I made sure they had enough water to soak up for the next step. That night I turned a heater up to full so it got to 120* F in there for 45 minutes. It seems to have done the job for me!
 
I also watered them with aspirin water 325 mg per gallon of water. and they loved it! 

I'll post up some photos of leaves after now that they are growing again. 
 
So here are the after photos of leaves that have grown so far after the treatment I did above!

So my treatment was as followed, I had an infestation of broad mites or cyclamen mites, I could never truly identify them even with using magnification, they are that small!
 
On day one I pruned all effected leaves off of the plants, put them in a bag, and burned it. Really, burn it. 
After this I used Bug B Gone on them Bifethrin is it's main ingredient. Do this at night so it can dry and is not as harsh on the plants.
5 days later I sprayed them with Malathion making sure to get every inch of them, underside of leaves especially. Again do this at night
3 days later I sprayed them again with the Bug-B-Gone at night. 
The next day I watered them very well with Aspirin water (325 mg per gallon), the soil was soaked and for good reason. That night I turned my heater up in my greenhouse to 120* F for 45 minutes. After that time I opened all vents and doors so they would cool down quickly and used a foliar spray of Aspirin water (yet again 325 mg per gallon). 
 
I have been watering them with Aspirin water since the infestation and they are loving it! Apparently the Aspirin helps stop the toxins that may be in the leaves still and helps to make sure they don't do anymore damage.
 
Hope this helps!
 
Glad things are turning around for you, but this one….

…. looks like it has the beginnings of fertilizer burn. Back off and just give them clear water a couple times, then when you resume use it either less often or at a lesser strength.
 
One of my shade cloths came off the top of the greenhouse for a bit and they got some sun burn on them... But thanks! I've been giving them just the aspirin water for now until they come back to normal completely.
 
I had some plants do this last June - about the time that farmers in the area were cropdusting.
I later picked the leaves off and they built new ones.

     Yup! Thinking scientifically saved my crop last year. I was in a panic (thinking I had broad mites) and was ready to spend about $100 on miticide before my wife ( a plant pathologist) talked me into getting some samples looked at. Since zero mites were found, I still needed to figure out what the hell was stunting my plants. I mean I had 2' tall OWs that COMPLETELY stalled growth on EVERY shoot! AAAAAAHH!!!
     So I cooled down and did some reading. Figured it was herbicide that some dickhead neighbor probably sprayed on a windy day. All I needed to do was trim off the affected foliage to remove the majority of the chemical from the plants' systems, and… BINGO! Problem solved, very cheaply and easily. Plants started growing again. Bumper crop season! BOOOYA!
     I like to think that the money I saved by not buying expensive miticides was better spent on the hhwhiskeyt U'm drinkn raaaaht nau!!!11!!

     I think so. It'll be hard, tho. Talk to elcap1999, he's a veteran broad mite warrior.
 
Upon triple checking my damaged leaf pictures, I can verify that my plants were indeed affected by 2-4D & dicambia, since the damage is identical to the pics posted here, and no amount of neem oil/pyrethrum fixed them. I'm guessing that either the landscaping company that services my neighborhood (which was hired by the HOA), or the gentleman who mows my backyard sprayed it, since there's really no other reason for the damage to be so immediate, and for the pods to all just drop like that after an awesome harvest. In fact, I'll be spending the better part of this weekend cutting off the damaged leaves/branches, and letting new growth come back out until I'm sure all the herbicide is removed.
 
But as far as broad mites, weevils, and aphids. I highly recommend using neem oil and/or pyrethrum. Put the recommended dose into a sprayer, fill the rest with water, and spray thoroughly. Make absolutely sure to cover every nook & cranny of the leaves, since otherwise, one single missed spot will make the bugs congregate there, and you'll basically be starting all over again in no time. And neem oil & pyrethrum are both biopesticides, meaning they're natural extracts that can be used up tot he day of harvest with no ill effects to the plan or pods.
