Ok I have taken clones in veg and in early flower , both will root no problem. Depending on the strain some will go right back to veg others will not. Perfect example is the Deadhead OG I have I took some extra clones off her at 7 to 10 days of flower. They rooted no problem but wouldn't veg at all under 24/7 light. After 2 weeks I said fok it and threw them outside.
