when to start flush?

Flush whenever you want or skip it if you want. It makes no difference in the final product.

yo me espero a que esten casi la mitad de los pistilos marrones, para luego con 2 o 3 semanas cosechar, en ese periodo utilizo agua solamente o algun tipo de flush para ayudar un poco.

Wenn du ausschließlich Organische Dünger wie Biobizz benutzt hast, brauchst du nicht spülen wie bei mineralischen Produkten. Bei Biobizz stoppt man die Fütterung etwa 7-10 Tage vor der Erde und gut ist 👍 Ich würde, so wie deine schönen Ladys bereits aussehen, nur noch Wasser geben🤟

Hi friend, It's seems they've some nute deficiency... Looks like potassium( burnt yellowing) and phosphorus (brown patches) deficiency. If you feel the buds are hard as stone than I would start flush any time soon. Flushing it for a week maybe? That would give it another week to mature a bit more.

Hey Simoboy, nice grow there, lovely buds. We can do some checkups: 1. When giving water/nutrients, how long does it take them to drink it all up? If they drink it in like 1-3days, they still want to drink and in my opinion you can keep flowering them a bit longer. 2. Have you checked them with a microscope? If the THC looks milky and not 100% crystal, they are ready to get harvested. 3. Your ''hairs'' on your buds are Amber which indicates that she is ready. 4. You have some nice collors in your buds, if you have a strain that does that, it will do that in the last stage. Overal i think your plants are ready to get harvested, but you should check option 2 if you have one :) Goodluck :)
