I used to use mix #2 plants did great, back then I didnt know about ph or bugger all, still got great smoke. now I do aeroponic but still use the flora micro, gro, bloom food, but any good nutes will work.
I would switch back to 18hr cut a bunch of clones off then hack it down to about 6 or 8 inches, as long as there is some green left down there... then let it recover a week or two then flower.
you will get a stronger shorter bush... I think with new weight on top the bottom may not hold. but it...
I tie em down for a couple of days as well.. works great, just long enough for the plant stalk to stay there.. then pick a new spot and tie it. I can make one plant cover the whole room if I want, as long as you can give the roots room and lots of food
Probably a crappy plant to start with... I have abused good plants and had great smoke and tried hard with bad strains and bad smoke. Just smoke it, it wont get better, holes or no holes
