depending on the strain growth at the spot u topped it will happen quickly within a couple days and the lower branches will get bigger meanwhile. not all strains respond well to topping or fim'ing, its usually the ones with good branching that grow vigorously that benefit the most. Some will only grow two tops very close together after you top them, and the lower branches still dont do much. my og kush was like that. however my critical + was very easy to get mutliple branches. hope that helps. looks like yours is done just fine.
