Hey JogaBonito521 well when you look at your plant do you see any of the white hairs dieing back turning amber color? If so then your getting there, I see from your picture that you have all white hairs so you may have 3-4 more wks give or take. Get yourself a 60x-100x microscope there great and will allow you to look at your trich's production. If you see that there milky or opaque your getting there you should wait until most are amber in color. Start to flush when most of the pistals or "hairs" are amber or red color and the trich's are starting to turn amber. I like to flush for 2 wks with just plain water that is sitting out for 24 hrs. I like to use LOTS of water, then I use a product called "Clearex" its a salt leaching solution you mix in 30ml per gallon of water and then water your plant. Make sure its still ph adjusted. Happy growing. When it comes down to it and you think your close take a few close up pictures as close a possible and ask us again.
