he's right about the counting of flowering time. also, he is correct about the yellowing fans. this is prefectly normal as a plant flowers it will use up food from fan leaves to put into bud production.

the red on the stems can be an indication of a nute deficiency or could be part of the strain.

the fan leaves and plant structure don't indicate a sativa dom IMHO.

as far as when to harvest, you need to check the tirchs to figure this out. they go from clear to cloudy to amber. amber is over-ripe and if you let them go too long the THC will start to degrade quickly although the plants will pack on a good more bit of weight. this is a common trick that commerical growers use.
