they will still come out great, but you must take cuttings now...( you can
take them from 4-5 weeks old until the 2nd or 3rd week of flower at the latest)...
I will copy a shortcut to one of my many cloning threads and I have a cloning tip at the end that shows you the best length and size of cuttings...
You can disregard the cloner system info there in the thread if you wish.
