Yeah you can lose some potential growth, but if you flush when the thc is getting close to done you will never lose that much, like instead of 100g you may get 96g but what does it really matter? If you decide to flush with still about 3 weeks to go you might drop to 60g instead of 96g but you are not going to do that, are you?🙂
That's right, you won't, you know better than that.
