Something is very wrong- I have NEVER seen leaves as round as that, they look like a different species even lol, but those ARE stress leaves. I think that plant is getting light when it shouldn't be. But no, it's not ready to harvest. That is very seriously weird.

Could you get some REALLY good pics, like of the whole plant and then some closeups of the round leaves at the top, not through the plastic of the greenhouse? That is some seriously bizarre growth. I'm super curious now!!
Nice to know i am not the only one freaked out by that plant lol,

Looks like her mom rolled around in the sack with something other than a male ganja plant.....pretty interesting...
lol this sounds liek what i am thinking...
