If it's 63 days into flowering, then I would say it's probably ready to harvest ASAP. However, without being able to actually see the plant, I couldn't say for sure. Do the buds look filled in? Can you get some pics up?
If all the trichomes are milky, then depending on what type of high you prefer, I would go ahead and prepare for harvest. Remember: milky trichomes == body high; milky and amber == body and head; amber == wtf can't get off the couch.
Also, is your plant hydro or soil? Either way, I would start flushing it right away.
