Im still new to growing and have only worked with photos so far. But im pretty sure the clones wouldnt have enough time to recover and produce as much as the original plant would. The reasoning for that is because autos are on a set biological clock once sprouted, unlike photos which use light change to switch to flower. If you were to clone I'd imagine it takes at least 1-2 weeks for them to prpduce new roots, so thats 4-5 weeks. Which leaves about another 8 weeks of growing left, only two of which are going to be veg. Like i said, im still new to growing and have never worked with autos. So i would love to hear what a more experienced grower thinks. Happy growing man
