Yup Mzn kinda said it all really.
Keep an eye on PH, anything that might stunt the plant will seriously reduce yield.
I always use a bio bloom grow, and top maxx all the way through the grow until the last wk to 10 days...Use 1/8 dose of grow nutes(as your soil will have enough nutes in it from start to finish) and start off using 1/6 bloom stimulant,like top maxx,then build it up to a max of 1/3 to 1/2 recommended dose...
They absolutely LOVE molasses, use it as soon as they show sex...1tsp to a litre of water, use every other watering....flush every 2 or 3 uses...then re-apply as before.
Personally i harvest when the trichome ratio is around 40/50% cloudy and 50/60% amber..Thats what i'm smoking now, and its a nice up-high thats also quite couchy
They usually take a good 14+ days over the breeders 60 days, in a greenhouse you will probably be looking to around 70-85 days from start to finish...but theyll be quite fat by then

Indoors they finish earlier,usually around 74 days is prime picking.
dont use pots that are too big either... i tend to use no larger than 1 or 2L, and theyre fine in those.
Males show sex around day 17, females tend to be around day 21-24
theyre an easy grow, they dont yield badly(as some report) if you you grow them with sufficient conditions,with some nice bud to be smoked at the end
Enjoy
