spidermite and aphid control

yep ... you know them you hate them... my worst enemy and yours..... SPIDER MITES!! Fucking bastards... coming on in week 7 like are you fucking serious???? Normally I am 100% willing to violate the Geneva conventions and wage some chemical warfare against these bitches... but week 7... you...

So I am currently in week 4 veg and the spider have begun to appear again, I had them on my last grow but around 2 weeks before harvest and now they have appeared really, early any tips on how to get rid of them, I have tried neem oil, defoliation, dr shimo and they still persist, anyone know...

I am wondering if Doktor Doom's Premium 3 in 1 is safe for organic growing? It is 96% Canola Oil, but what is in that other 4%? Has anyone used this before? I hear that it is safe to use in flower and on veggie plants up until harvest, but outside of this I am not finding too much information...
