well to start off you should buy a N/P/K test kit and go test the soil your lawn grows in it will show Very basic amounts. WOW AMAZING, MATHER NATURE HAS NATURAL NUTRIENTS?!?! DERP. use your brain, everything NEEDS food to survive, dont believe me? stop eating
go read more. FLUSHING is flushing the nutrients out of the plant duering the last 2 weeks of flowering. this can be dony many ways such as spiking the PH of the medium to stop the absorbtion of nutrients, as nutrients can only be properly absorbed with a PH below 8.....
leaching salts from the soil is a totaly different subjest. you must leach the soil multiple times duering a proper grow to ensure a PH above 6 but below 7 (hydroponic growing as an exception, average PH being 5.5.....and flushed almost daily...)
actualy most rain water measures 7..... thats 120x the "PH" of 5.8.... as PH is refering to the concentration of hydronium atoms in a specific medium, and each full point of PH represents a complete 100x raise in the concentration.....
"feed it with water with a ph around 6.2-6.8.the plant is now able to take in nutes" thats the only thing in this entire paragraph that made sense. first off the plant doesn't "go to sleep" when it rains, it "sleeps" when the lights are off (uses the least amount of energy for the most amount of growth.....sleep). when it rains it is simply washes off the stomata on the bottom of the leaves allowing for proper oxygen/CO2 absorbtion.
1 last point. the point of this thread is IS IT POSSIBLE. and yes it is, and its a good way to start to. lots of people on here hate about "the right way to do it" WTF are you talking about RIGHT WAY?!?! there is no right way. we have been growing this shit for over 8000 years and smoking it for close to 4000.
EDIT: you wanted an easy male:Female notifier. well here ya go
