I have some courgette plants in the greenhouse. They are growing well and have flower buds forming but just the last week or so they have gone very yellow. I fed them today with some tomato feed. Have I done the right thing...and what could be causing them to go so yellow? The first pic was taken 27th April, the second one today. As you can see, it looks healthy enough. It is courgette 'one ball' which has a globe shaped yellow fruit. Perhaps it is supposed to be this colour!
