My tomatoe's are now in their final pots sunk into a bed of gravel, they all have 1 flower truss each, with the flowers just starting to open. Up until now I've been feeding to promote root growth and am wondering when to start the high potash feeding, do I wait until I see the first fruit or do I start now?.

i grow toms in ring culture and last year a waited till the first flowers had set before feeding from the top and watering from the bottom
