Leaf Margin Burn Issue: Under Canopy Secondary
This is one of those weaker secondary vines that is slowly growing and since it is behind it is under the fully mature leaves. As a result, it is getting minimal light. Many growers would have removed it, but it was kept since it was still growing and could be needed if some of the other leaves were lost later in the year and did not seem to impact the pumpkin growth.
However, this was an important key to figuring out this marginal leaf burn issue. It seems these leaves are the most impacted by the yellowing to the point that there is also marginal leaf browning occurring.
Alone this would not explain much, but with the shaded leaves showing more yellowing than those in full sun and seeing this leaf which is the most shaded showing the most yellowing lead to a potential pattern.
