wait till you get new pots then as said top & trim the bottom spindly branches off(will make the other branches bigger &get a bushier plant

) then wait for at least 1-2 week for plants to recover from the stress of transplanting & topping etc, + extra vegging time makes bigger yields

, then away you go ,you have plenty height, width so no worries about size as their not too tall just now.
all the best
