need advice taking clones

plants are 22 days into flowering, clones were taken 4 weeks ago and they all are dying or dead, I know what happened to them my fault never should have left them for four days, short costly vacation. My question is can you take clones from flowering plants?

Yeah but they will become stunted and often tend to mutate. On top of that they also tend to take about 4 weeks to begin veg growth again. Best to start with some new seeds or clones.
