Not sure what's going on but I don't like it. 1195 Holub Squash looks the worst. Any ideas? Link to diary below:

I have a few pictures following the one in the link.

Did you do a soil test? What are you your squashes and what amendments did you put in your patch?

Yes I did a soil test and added amendments per Ron Wallace's advice. Plants were growing slow up to this point but then this happened. Hoping the plants will be okay but I don't think the main vine on the squash grew at all the last two days.

Its definitely to much N and then it looks like there's something else going on?

Potassium because of the light tan to brown leaf edges and Magnesium because of the yellow leaf. Maybe some iron/zinc also. That would be my GUESS . If the plant stopped growing for a couple days it maybe setting roots deeper and along the vines getting ready to GRAB and GO. I use blossom boost 0-52-34. Hopefully someone with an eye for the leaf can give you a solution.

Jay it would be best to send in tissue samples. Test is about 45 bucks. Then you will know for sure what the issue is.

Disease is another test which runs closer to 100 bucks

Did anyone spray any herbicide near the plants?

I did spray weed killer around the perimeter of the patch but I tried to be very careful as to not let any drift towards the plants so I doubt that is the issue. No can do on tissue testing. Just too much $ for a hobby grower like myself. If the 1195 Holub doesn't look better by this weekend, she's getting yanked and tossed in the trash. Thanks for all the ideas. I sprinkled some epsom salt around the plants and watered it in yesterday. I doubt N is my issue because the plants never really were that green and healthy looking. Plus I thought N would cause massive vine growth which still is not happening.

What was in your weed killer? Glyphosate? 2,4-D? Looks similar to 2,4-D drift damage.

I used Round Up but do not believe it could have gotten on the plants. Plants are not growing and main vine's are stiff as a 2x4. I believe something is off with soil or something I sprayed. I have other decoration pumpkins in separate patches and they look fine. I have used mostly the same stuff on these plants. I'm stumped. I looked through all the pumpkin diseases and nothing matches what I'm seeing. Best guess is user error. Even though it's late in the season, I planted some misc AG and squash seeds around the patch. Looking for a Sept 1 pollination. Ouch haha

I think Roundup got them, I did the same thing. I would have bet someone a lot of money mine didn't get hit, I would have lost the money. Especially entries 176 and 179. You'll know in a few days if it was Roundup, the leaves will be almost white

Along time ago I sprayed a plant with a generic round up .... just to see what would happen and I still had a fruit weigh I think 700 to 800 now I would not recommend it but the plant shut down for a lil bit but came right back there was about 2 feet of yellow and white leafs then one day she took back off maybe some time is all that is needed

Thanks everyone. Keeping my fingers crossed. This morning I checked and think I got some minimal growth. Gonna water the heck out of them today to try and flush them out.

Soaked plants real good plus we had some rain. Anybody know a good molasses to water ratio? I have a gallon but afraid to use it.

In tea I use about a half a cup to about 3 gallons I say about as my wife would kill me if I used her measuring cups in the garden so I eye ball it....

Good luck ...I would be careful with the water or you can have trouble getting any sets

Jay do you use eagle? Myclobutanil? (same thing) That will cause the leaves to pucker like that especially if it goes on to heavy on the vine tips

I would give it some more time and back off the eagle, before ripping it out.

i just saw entry 185 in your diary, that would be pretty extreme for eagle damage. That does look more like herbicide damage. I would cut that vine tip back to where the leaves are more normal and retrain a secondary as the new main. You will be back in business in no time. Is there a chance you used the same sprayer that you had put herbicide in before to spray your pumpkins. Some herbicides will impregnate in the plastic if allowed to sit in the sprayer. Then you go and use that sprayer for something else even if you triple rinse it, you will be spraying your pumpkin with herbicide. Pumpkins are very sensitive to broadleaf herbicides like you would put in your lawn to kill clover and dandelions etc.

I think it will grow out of it

I did use Eagle but after these symptoms showed up.

Update. 1044 Gansert has recovered nicely. Secondaries putting on about a foot per day. 1385 H/J and 1662 Steil are coming along. Main vines on all three plants are twisted from where they started growing again. Secondaries are as well but not nearly as bad. Now I need to get a pumpkin to set on each plant. It shouldn't be this hard!! Haha

Oh I forgot to mention that my tissue sample didn't show anything toxic so my best guess is the drift from round up hurt my plants. That will NEVER happen again.
