Socal!
I like that you're using fabric pots. I'm a newbie too, so it's not like I've got a track record, but the fabric pots just make sense to me. I like the idea of the extra air exchange. Plus they're awful hard to overwater.
If you don't mind I'd like to make a suggestion. Even the fabric pots will stay damp in the bottom couple of inches. We bought some heavy duty baking racks and some stainless steel pizza trays. The SS pizza trays were expensive, about $16, but I'm glad we did it now. Even though the racks are fairly stout, I figured they were gonna bow in the middle so I cut a 1/2" thick ring from a scrap piece of 4" PVC with a chopsaw. Place the PVC ring in the center of the pizza tray and set the rack on top of the ring. The rack is supported by the rim of the pizza tray and the PVC ring in the center. The fabric pot sets on top of the rack, and now you have 360 degree air exposure. If extra water runs out you know it right away. Every week or two pull the girls out of the way and clean the pizza trays. They'll shine up like new. Every day I spin the plants 180 degrees. It's easy because the metal rack slides on the pizza rim and the PVC ring.
I FIM'med our girls and all I got was two unhappy plants. And four nodes of deformed leaves slowly maturing for weeks. I felt like a real creep the whole time.
And both plants continued with a single main branch!
I've only FIM'med one time and that's the last time. What I tried next was putting on some hobby visors, the ones with the magnifying lenses. Grabbed some very pointy tweezers, dipped in alcohol. I carefully spread the top out a little bit with my fingers and plucked out the teensy, tiny, itty bitty little nub of the newest growth. I mean, we're talkin' smaller than a BB small. Even though the tweezers were very small and pointy at the end, the greenery barely peeked out from the metal tips.
Unlike the ugly FIM experience, the plants didn't seem to be so offended. Within 2 days it was clear that they were finally going to branch for me. And I didn't have to look at all those mauled leaves for weeks like before.
In my newb opinion, FIM is something that's gained a following and become "the thing to do" when it's not any more valid than other techniques.
