i say trim the tops off the big ones and they will bush out while the others catch up or you can also pull the highest tops down to the level of the lower ones wil also make a bush you can hold them down with string ect tied back to the pot or i just use fishing weights and adjust as needed as the plant grows. topping them will produce more main stalks and be better and you have the time to wait as the others catch up. good luck everything looks great. Just wondering what do they charge for a tiny little baby like those.
