To try to give an answer, if you have a Scrog net that I do not see, then harvest around it and through it so you can use it again. If you have strings holding certain branches down or up or whatever, feel free to cut your string and toss it away, unless the sting has some sentimental value. Best answer I can give when I'm still really guessing at the question. Good Luck and Happy Growing...;o)
You've got a long way to go before harvest. Cut the branch and pull it out of the scrog. When its harvest time it will be self explanatory.
