don’t know about an oil,.
opinion is i wouldn’t think anything that is able to be used on a marijuana plant could damage it unless used recklessly,.
remember these plants i have growing right now were infected with broad mites not spider mites, broads are way worse,. i soaked my plants in 50-60% isopropyl every other day for 6 days, totally wiped the mites, and didn’t leave a speck of nothing,. just posted an update yesterday of these plants, almost finished now,.
see if i find anything about sprays or oils,.. though im not a foliar sprayer of anything unless it’s pests or mildew,.
