I'm on my fourth grow but I'm still experimenting with all that can be done to M.J. plants. I wanted to know if I can still top plants off on the lower branches when I'm in flowering week 4? I have seen some growers do it on you tube. I just wanted to see what other have to suggest. I have already topped the very top coloa a few weeks back and there as been a positive result. I just topped off the lower. Branches last night... so now I'm worried if I did more wrong then good?
