drainage troubles

Hey all!
I'm having some drainage issues. 3 of my plants arent draining like the rest of my ladies. I watered 4 days ago and there is still water in the soil. where as the others are dry and wanting more agua.
What should i do with these 3? There in 3 gal buckets, I just transplanted 2 weeks ago, my cabinet won't hold anything bigger than 3 gal. buckets.. so I can't go any bigger there.
Can I take some long skewer like thing and poke some holes in the soil carefully not to fuck with roots to improve drainage?
I'm planning on switching to 12/12 in a week.
Thanks for anyinput

I'd say first, "what's your soil mix?" and 2nd, "How many holes on the bottom of the pot?"
Water the other 3, but I would say hol back on the 1 having the draining prob

Hey MBA, actually its 3 of my 5 ladies are affected by this, the other to are doing great.
I'm using ffof with about 25-30% perlite added. I'd say atleast 8 holesin the pots, I bought square pots at the hydro store. I can't figure out why this one is not draining, I transplanted them all at the same time, did everything identical to each..
