well, what week i swap them over is a bit subjective. it really is dependant on the plants. once i start seeing amber trichs in larger amounts i know its getting close. flushing for me anyway means i water it to saturation not so much by volume and it also means nothing but water for the last 2 weeks. unfortunately growing in soil means that flushing has a somewhat limited effect as far as completely removing ferts...unless you manage to actually deplete the soil.....

as for strain. right now its northern mexican aintgotnoclue...or bagseed. i havent put any money into seeds yet for a myriad of reasons but mainly im a cheap bastard and honestly when you grow it yourself you can see what it was like before it traveled poorly, trashcompacted etc. by the time its gets here its a shadow of its former self. i also only grow a few plants at a time as its only for me and a few buds if theyre short. the ones i have now are starting to get obnoxious. when i open the tent i get hit by a powerful stink of a fruit eating skunk that crapped in a tub of fermenting corn. it was so strong this morning i thought i was gonna guff but it settled down. so maybe its a sour diesel??? dunno tho but i know it will be way better than the product the seed came from once i got it.
