Hi everyone.
On my 2261 Wallace the first 10 side vine leaves are normal
Then after that the leaves changed shape looking simular to a watermellon leaves. Tissue testing is just to expensive her in South Africa. Has it ever happend to everyone and and if so did it effect the fruit at some stage?

Start a grower diary and post pictures, then other growers will see exactly what you are talking about and may give more detailed advice rather than just guessing.

Last year, when my plants had a mosaic virus infection, some of their leaves developed different shapes. However, if everything else seems normal (color of baby pumpkins at the female flower buds, color of leaves, thickness and growth rate of vines, spacing of internodes for the new growth etc.) this new leaf shape might also be a response to your local light and temperature conditions. Currently your plants are experiencing the longest days, and if this is true for the actual hours of sunshine as well (i.e., hardly any clouds), the plants perhaps try to minimize evaporation (still being able to perform photosynthesis at a decent rate because of light intensity available) by altering their leaf shape.

Symptoms like that would most likely be from a virus or herbicide. Like pumpking said pictures would help to diagnose the problem.

My guess would be a change in water availability is changing your nutrient availability. Subsoil getting dry maybe? You can dig a hole for free anyhow. Possibly omething might be eating your roots?

I would throw a water soluble fertilizer, and plenty of water at it. I am guessing you are in the mid teens or early twenties for days after pollination. The soil in not fertile enough, or is in excess of something.

I have made a growers diary with a photo.
The fruit itself is growing very well. its actually growing a bit better than last season at this point. The leaves are healy but just deformed . Some of the side branches i have noticed are getting better in shape bit rhe main vine is getting worst bit the leaves are still looking healty

Very interesting peet. The leaves look very healthy and your fruit is doing fine so its not gonna be a disease issue. I believe its called epigenetic effect. The deep lobes is genetic and something in your environment is causing it to be expressed. I had the opposite thing happen this spring. My seedlings first 4 or 5 true leaves had similar lobes and the plant grew out of it.Mine happened on A 1911 urena seedling and caused me to plant it as a genetics plant instead of putting it in a full sized plot.
