So if it's a true auto it's best not to clone at all. And if it's a photo you're perfectly fine to take clone in flower and reveg it. It's actually one of my favorite methods. I reveg a lot of plants.
That’s the down side of autos,unless you’re making pollen,
that’s the nice thing about photo plants,haven’t grown any photo plants in a while now, I do have some female photo seeds I made,
Maybe I’ll try a photo plant I have a shit load of seeds,and another tent,after growing autos for some long takes for ever to grow a photo plant lol
I have Romulan,purple Urkle god bud blue cookies, maybe some mango kush photo seeds
and I have lockdown strain I made Romulan/purple urkle,and a few
Other have to check my seed bag
