Flowering question! Week 6

So i am on my first grow and i had a relative come by and take a look at the garden and he was in disbelief that i was in my 6th week of flowering. (Possible autos) (i know when i switched the lights) could someone give me feed back on if i'm on pace for a 8-9 week cutdown because i am planning for a 10 day flush.

His concerns were that it is farther into flowering then i thought and maybe the seeds were autos by mistake.

Thanks, sorry for the purple pics!

Never a good idea to try and judge a plants age by a date. Get a microphone and check the trichomes. Seller flower dates are merely a guide line. You want mostly milky, 15-20% amber.,

Just bought one thanks
