Where are you? First you state "It's hot here", then you say "it's getting colder in my area"
Well, even in sunny CA it isn't squash growing weather!
Let us know your circumstances, please. Nancy

The OP is from Israel and I've posted the link to the other discussion. Sorry, don't know what to tell you other than squash don't like to be transplanted. People have already suggested this might be the cause on the other thread.

Here is a link that might be useful: Problems w/ winter squash (please help!)

Environmental. Ran short of water.

If temperatures are excessive, plants can run short of water even though the soil is moist. The reason: the stomates close; transpiration stops; so limited or minimal water enters the roots and is distributed throughout the plant.

Temporary shade can sometime meliorate the problem.

You really need to include your location info in the box provided. The "none" doesn't help us in any way. So thanks Rodney for the info and the link to previous discussion.

I agree with Jean's diagnosis. But regardless, based on the photo it is a minor issue and nothing to be concerned about. Far more important an issue is if the plant will ever produce anything given all the transplantings it has had.

Sometimes things in the garden just don't work out.

Hey! I'm so sorry for not mentioning the location...
But it seems like my Squash has some more baby squashes on top of the vine, so I think I will leave it like that for now and hope for the best :P
