Hmm ok that might be possible as well. I never did pure sativas, but read about them not needing that much food.I think I overfed the PNG Kashmir, believe it or not. I gave it a heavy bloom topdress a few weeks back and it didn't like it. It's still growing out of some weird leaf curling and yellowing. I think it could be stunted and that's why it's flowering so slow. The tall Columbian kindof slowed down after that topdress as well. I have been lowering the amount of topdress and increasing nitrogen a bit for the long flowering sativas. Gave plain water yesterday. They are putting out more flowers now as well. I don't have any numerical data for this grow. Just a spoonful or two of terp tea dry amendments when I feel like they need it.
So you are saying not the full dose of nutrients. I will try to keep that in mind when i grow mine.
The structure for fat buds is given ^^
