Hi,

This is my first year of trying to grow tomatoes in a greenhouse. So far
things seem to be going well, the plants are in growbags and seem to be
thriving. I have not fed them yet because the food says to wait until the
"first fruit has set" before feeding. I am not sure what this means
exactly - the plants are beginning to flower but should I wait until I see
small tomatoes forming?

Thanks,

Jim
