Bro I'm sorry I dunno what that is! I cant imagine the stock splitting into two after that, thats for sure. The objective of "TOPPING" is to get the main stalk to split into two. When the new growth is still nice and tight, you can cut the new growth off completely (not the stock completely). Like so..
The objective of a fim is very similar to the objective of a top. Its to get the main stalk to branch into MULTIPLE tops though. FIM simply is a top, but instead of 100% of the new growth gone, you cut about 70-80%, leaving about 20% of the new growth intact..like so.
As for organic nutrients, I would try anything that is most simple. I really like the Fox Farm Big bloom, its basically just bat guano and is 100% organic. Molasses is great too, but you really gotta put something in there that is a good additive. I would try some liquid AN Big Bud (not organic) and some AN Overdrive. It will really, really help your finished product. After that, just give it a long flush and trust me, you will taste nothing but sweet earthy OG.
