Hi matey Im coming up to a week into flower with mfg, and we noticed a couple of the little buggers last nite.
I spent 8 hours on this exact subject, and the result was "100% ORGANIC PURE NEEM OIL"
I bought some off good ole Ebay for like 4 quid (7 euros, 7 dollars) you mix a bit with water and just spray - and cos its ORGANIC you'll get no nasty effects on ya baby..
Good luck
