I feel that the using frequently soluble fertilizer like 20-20-20 or
10-52-10 may be the cause of yellow spots on the leaves.
Field pumpkins expert from local extension agricultural services said to me
that cucurbyte are very sensitive to salt build up at root level from
soluble fertilizers and that lead to yellow spots at the fringe of the
leaves.
I grew a 723 Bobier clone this winter in my house with 20-20-20 and many
leaves had yellow spots. At present in my patch, it is the only plant with
yellow spots on few leaves. Now I'm using granular amonium nitrate 34-0-0 as
source of nitrogen.
Hope this help
