1-2 weeks and you will see bud growth. keep the humidity below 70 for the first month then below 40% for the rest of flowering. feed it Veg nutes for the first 2 weeks of flowering then SLOWLEY switch to flowering fertalizers. this will alow your plant to keep its fan leaves. 1/2 way through flowering stop feeding them nitrogen, this will make the plant eat the food stored in the fan leaves and put it into bud growth.
