4 Weeks into flowering.... and ROOT bound =(

I'm in a dilemma here. I'm a little over 4 weeks into flowering for my first grow and I finally ran into my first big n00b mistake, (or at least I feel it is). I should've transplanted her when I put her outside a month ago, however I didn't predict her to bud and grow this fast. I have her in a 2 Gallon pot (I KNOW) and I need to get her roots spread out again to flourish...

I've been told I can do what's called Layer Caking, where I poke holes in the side of the pot and get a pot size larger, fill 1/4 with dirt, place smaller pot in, then put dirt around the rest of the pot. The roots ideally grow through the holes and develop in the soil of the bigger pot. Has anyone tried this and has it been successful?

Should I just transplant her and deal with stunning the roots? or give "Layer Caking" a shot and if so, do I just go one size up, a 3 gal or should I just go ahead and get a 5 gal? Since this is my first grow, and I'm this far along, I really don't want to mess ANYTHING else up. Any advice would be appreciated. I need to do something this weekend about it or she'll probably start to die ever so slowly. =/

If its that rootbound, you should be able to pop out the whole thing out of the current pot into a larger one without damaging the roots

It's not recommend to transplant in the middle of bud cause u don't want ur plant to use energy to grow new roots u want it to use on bud production how big is ur plant in the two gallon pot?

It seems fine enough..........I wouldn't screw with it. Just water more often. You may want to yank the whole root ball out and add some fresh soil to the bottom of your current pot but I think you'll be fine.......

Repotting is fine as long as you transplant them into the same medium they are in now.

That pic was also taken a day after watering her, which tells me she's root bound cause the bottom half just keeps getting worse...

I'm using FFOF, and my only question if I transplant with that is I'd have to stop adding my nutes right? I'd basically just be going all natural up till harvest no?

Did you end up transplanting , or did you just continue in the same container? Can you update me on your plant situation?
