I just used B'cuzz Hydromix HP and now the rooms I used it in, are infested THIRPS

Hi I have been using this B'Cuzz for over a year and 2 weeks ago I bought 4 bags from a small store I have never bought from before.

So that day I used 1 and 1/2 bags to transplant Plants into larger pots from Veg and then put them in one of my 12/12 rooms. I also used the new mix for some new plants that went into the Veg Room.

So both these rooms are full of Thrips but my other 12/12 where I never used any of this new B'Cuzz mix i cant find any Thrips in there.
Could I have got this things from these bags??? and I just notice I have this shit that looks like Cotton growing along the top of the 1/2 bag I have left. It was covered really good in a garbage bag.

THanks

dang... nice pic... lol ahem... I would use Azatrol or Azamax ( same active ingredients) for your bug problem...follow the directions.. it works great !! And it is safe to use right up to harvest, but once or twice is all u will need... very effective also, sadly, yes the new store may not have a good storage area, thus letting the contamination happen.. sorry... Good luck and keep on goin !! Peace

Hope this store wasn't in Ontario because I just bought a bag of this stuff from a small store and will be using it in about a week when i do my first transplant........
