JS,
The only cuts that will root and grow anythign are the ones that have a growth tip. It looks like some of yoru cuts are only leaves, and the little part between the leaf and the stem that is where the new growth happens... is missing or removed, or dead?
Next time make sure you keep the top growth, and if there is a bud, then that is fine. NEW GROWTH WILL COME OUT OF THE BUDS>
See the power kush in t he top left of the pic? that has two growth points. that one will make it. Hard to see the rest, but it looks like they may not work out for you.
Here are a couple of examples of two colombian phenos I needed to clone last minute. Taken around day 15. These rooted in 7 days, and are just startign to grow out again.
Its possible to create hermie trats this way via mutation, so its not good to make it a habit of changing light cycles. However, if you want to save a strain and you arent breeding it, its worth the risk.
