Also wipe the underside of leads if you aren't taking them there'll be eggs on the underside inbetween the gains, and also they'll lay a little below the soil.

Well your tackling it right. If I were you I'd try catch as many of them little bastards as you can before harvest. Have you got any bug traps the yellow pads. Drop then and even cut them down and lay then inbetween bud sites up and down the node and remove all there webs first so they have to walk over the areas where you laid down even very sticky double sided tape, and you'll catch most of them, also if you have any peppermint oil it's also great to put it around the time of your bucket/pot and leafs. Put some on cotton wool balls drop a few around the base and even near your buds it'll drive them mad and Into your traps, again the more you catch the better and if your getting that close to harvest you'll lose most of your leafs in the flush so why not take them make it harder for them to move around forcing them to travel up and down the stem, across nodes, where your sticky bug traps will be waiting. Good luck buddy nice grow.
