leaves turning green

[flowerpot07]

Hi everyone, i have had trouble with my computer,and somehow couldnt find this forum after googling today, i have now found you

back on topic, some of my petunia plant leaves have started to turn like a lime green colour, could this be because the weather has been so wet lateley.
Or is it because they maybe need feeding?

And talking about feeding, i bought some universal plant food sticks, but havent used them yet.
Has any one ever tried these, and if so do they work, i usaully use miracle grow.

Where are your petunias? Pot or open ground? what size pot? Outside, indoors?

They are in hanging baskets and tubs, it seems to be the bottom leaves that are turning light green.
