What's up,I'm in SE Mass,been doing it since a kid ,now 50's,only probs. I've had in 35+ yrs. is some bugs and botrytis,after yrs. of this I use a habenoro pepper spray I make to make interested animals LEAVE ALONE,come June add gentle Murphy's Lemon Verbeena/Chamonille Soap to my pepper spray mix and hit the plants at dusk ev 2 wks or so,End July I might add a little insecticide that's reasonably natural(Prythrin) made from the Chrysanthemum but not always,only if I actually see bugs , if not just the soap/pepper mix preventively as needed Late Aug/Beg. Sept. I'll add BT to the pepper/soap mix,this stops any egg/larvae from moths that turn into the bud worms we all hate. Ideally I so this 10-14 days into flowering,From then on ,I won't spray anything on my plants again and just watch for PM/bud rot.I'll pick off rot a bit but if it starts being a habitual thing it's chop time for that plant,botrytis is a rain/humidity issue and all you can do is shake your wet plants,no spray or decent thing to stop bud rot,some people use h2o2 hy.peroxide but it's usually time to salvage your plant by the time rot is a prob, you have thick enough bud,why keep losing it,and I don't really want anything applied to the actual flowers the last 5-6 weeks. Fert, wise I use phos. tea and will use a phos. synthetic fert at 1/2 strength twice,some Mammoth p,after Sept 14 the plants get nothing but water because I plan a 1st wk. Oct chop,weather usually determines,so I'd rather be sure my plants properly flush clean rather than have them nasty by fertilizing later thinking Oct is going to be good 2-3 wks in then being forced to chop unflushed plants by nasty weather.
