Lookin' good...

sounds like youve got plans on your hands...

i would say let them grow pretty big in those pots, and when the time comes to start flowering, re-pot them, use the bat guano and soil in the new pots, also, (if you have any) a few worm castings thrown in for fun should give them a nice boost too...

That way your plant will get a huge boost through the most part of flowering, which is always good

Do whatever you feel works best, im only saying what I would do in that situation... - good luck... I'm watching

p.s. are you gonna top one?
