I think that a air stone can def help, but I also think that you should back off on the LK and your plants will still look beautiful. IMO, the LK should be started about the week before flower and then throughout the rest of grow. I can't remember if this is how LW says he does.
LK is just an additive that can only do so much to help and then it is almost like using 10000 watts on one plant veged for a month, a plant can only have so much photo synthesis, in the same way, the plant can only absorb so many micro and macro nutrients. Also, an over use of certain nutes can over time cause nute lock out. With this said, you may have some reasoning behind your method that is completely viable, but this is my penny's worth.
