Love to see your actively growing pineapple! I did a similar attempt sometime rooting it in water then changed it to water gels, after which I stuck it in a soil. I used to have a thread here, but it got moved to somewhere..anyhow, I think if you have viable roots for the new ones, you can attempt to separate it, but till then, keep it attached to the mommy plant, eventually the mommy plant will decline as with any bromeliad.
I have seen pineapple plantations in the Philippines, where it is in constant high humidity, and always rains there with the moonsoon rains, and the plant thrives well. So your San Diego weather should be good for it, just give it good drainage.
My pineapple is ever so slow growing, still alive I think, but my humidity here is really bad, so dry here, have moved the container nearer our fountain, hopefully it will feel better.
