lime will solve your pH issues if need be, keeps the soil nice and balanced, and indi's right about the molasses chaze loves it but don't go overboard.
I personally would have had them in bigger pots mate, as for height supercropping is an option, mines responded well to it.
Putting your chaze on 14/10 won't hurt them, if anything it'll up trich production and they will come out frosty, I had mines on 12/12.
and last but by no means least "LISTEN TO STITCH" if he says it then it's gospel, after all he bred these babies.
