it looks as though I have root aphids in my 4 pot Wilma. I've had advice on other threads and used the search.i've bought neem oil and soapstones and also an insecticide for hydro. has anyone any ideas as to applying the neem to the roots? it's been suggested 2ml/litre when drenching the roots.also should I turn off my pump/drippers and do a res change straight away. and also how often should I apply this.i've about 4 weeks left of flower.
