Just a quick one-fruits sets?

When you start to feed toms it is after the first fruits sets (I believe anyway!) but not too sure what this means. 

Is it when your can see flowers, or when the flowers open, or when you can actually see little toms when the flowers have dropped off? 

I think it is the last one but not 100%

You've guess it right as far as the toms - when you can see little fruit.
