First time close to harvest.... but how close?

i'm trying to figure out when i should harvest... i'm growing casey joneshere are some pictures that i just took today, let me know your thoughts or suggestions please!!!i have links to photobucket for the pictures if these aren't turning out rightthis is my first post after all.i also have more pics, from clones to present day, and even pics of the build for the grow roomlet me know if you need more info or are interested in seeing the rest of my pics.the plants are currently on 12/12 under 3 x 400 watt HPS lights

Im only a noob myself but shouldnt u be checking trichlomes?

yes the above poster is correct.
get a 30x jewelers loupe and check the trichs.

you got a while yet still plenty of white hair

i need a stronger magnifying glass tbh, but from what i can see the triclomes are most clear still. i'm right at 8 weeks and i was told that casey jones can be a 9-11 week flowering cycle.
