just gave some lst.. still planning on flowering b...

I like to defoliate about 3-4 days before flower. Give them time to recover from any stress then flip, but I also lollipop so its a fair amount of stress. Once I start flower I try to avoid doing anything that would cause stress until stretch is done. That said everyone has different methods, only way to find what works for you and your plant is try stuff out. So short answer I'd do it in 3 days once plant perks up, then flip 4 after that. Good luck.
