pumpkins-yellow leaves & black bugs

ginamolyneux

Hi all, I am attempting to grow my first ever vegetable (Atlantic giant pumkins) and have noticed that some of the leaves are turning yellow, there are also tiny black bugs under some of the leaves, I would appreciate some advice on the yellowing leaves and also any tips for growing large pumkins, thank you

looks like a deficency of sorts.  Maybe a liquid feed might help.
