So I'm planning on making a batch of pyrethrum spray to rid my plant of bugs, but I'm just wondering how it will effect the plant, specifically its smokeability. How long before harvest should I stop using the pyrethrum?
About a week ago I noticed some brown/white tips on the leaves of my month-old plant the other day. Upon closer inspection, I noticed that the affected areas were also covered with tiny black specks. I figured it was a mold problem, but thought it could also be very small bugs. Does anyone...
