Nice update! I'm drooling over your Floja! What a gem! I love the coloring, it's just amazing!
Watering with neem oil doesn't work as fast as spraying, but it's way less messy! And stinky for that matter. I'd also suggest squishing as many of the buggers as you can. They splat pretty easily, but it requires some man handling of the plants to do it. I've managed to kill off an entire infestation with squishing alone, but it was hard work!
Also don't forget that with the time it takes for the neem to leech out of the plant you might not have enough time to use that method with some of your ladies. You don't want to use neem if you've got less than 4 weeks left of flower. To be honest, it looks like you've got a pretty good infestation going at this point. Judging by the pics it looks like the little bastards are munching on the Sensi Star most. I'd suggest floramite over anything else, only because it's a sure thing. With the neem and the ladybugs, if one manages to still breed after neeming or the ladybugs miss a little grouping somewhere, you're right back where you started. Also with using the floramite, you should be able to use ladybugs as well. It's not an all around bug killer, mites only. I know someone who tried using it for Thrips and it didn't work. Ebay has the best prices if you're looking for cheap. $15 for a 1 oz bottle, which treats 24 gallons.
I was half joking about seeds, but if you're willing, I'm game! I love the color changers! Currently I have 2, an Matanuska Thunder which only turns purple under extreme cold (which is probably not going to happen this grow) and a purple #1, which 80% purple out. Purple is still in veg, so we'll see!
I'm subbed for sure! Your Floja has me hypnotized!
