Hey guys I started my plant flowering 1 week ago. I didn't do any lst during vegetative, only minor topping. After 1st week of flowering I can already tell that they are going to be too tall, to the point where they will touch my growlight. This is also my first grow. I have 3 white widows in a 3x3x4 tent and they are all pretty bushy and tall. What should I do?
