Hi, so I always top my autos, and throughout the whole time, I keep defoliating so that the lower shoots get light. There are many who say not to defoliate, leave the leaves, but it works really well for me, and I get yields between 70 and 150 grams per plant in about 10 to 12 weeks. Except for my Membrana, that one is driving me crazy; it's now at 131 days. But that's another story :). I can recommend it to you, but it's just my opinion. And I start fertilizing as soon as I see flowers, a boost with PK. Nitrogen until week 4 or 5 of flowering, then just PK. Check out my diaries and get an idea. Good luck!
