too early to clone power skunk? help.

ok so i have a g13 labs power skunk just 4 days into flowering with advice from other RIU threads, early before signs of sex.

i would really like to clone this plant but i need to know, should i wait for the calyxs and pistols? or should i just break out the hormone and clone it?

help please.
