IF you work at a hydro store you should be aware that recommending neem oil on a plant that is within 3 weeks of harvest is questionable advice. The residue has an outrageously rancid flavor and odor, and will RUIN your product if used too late. There are other, better options. For sprays, I use SMC on my flowering plants up to about 1-2 weeks before harvest and STILL try to avoid getting it on the buds, even though coriander oil is nontoxic (and smells lovely). For use in that sensitive time right before chop chop, you can fight mites by dropping temps, adding wind, and removing webs with a small vacuum. But within 3 weeks of flower, options for dealing with them are VERY limited, which is why it is important to knock back all pest populations before then. A good method for this is a set of pyrethrin bombs set off 2-3 days apart- bomb twice at least, but three times is much better. Pyerthrin breaks down quickly in intense light, and kills pests instantly.
