EvenSteven Posted March 4, 2022 Share Posted March 4, 2022 Greets Peeps, Got a Northern Lights only a week or so into flowering with what looks like the start of PM, have been proactively treating with Neem Oil once a week : 1 Quote Link to comment Share on other sites More sharing options...
PsyCLown Posted March 4, 2022 Share Posted March 4, 2022 Yes, that does look like PM. Never used Neem for PM. Try some spraying sulphur / bio sulphur instead - you should get better results for PM Coppersoap can also work well, but only to be used in veg. 2 1 Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted March 4, 2022 Share Posted March 4, 2022 You can get some potassium bicarbonate and jadam wetting agent from pappajshop or follow the link. https://www.totemic.co.za/product-category/grow-essentials/ 3 1 Quote Link to comment Share on other sites More sharing options...
EvenSteven Posted March 4, 2022 Author Share Posted March 4, 2022 (edited) Thanks all, worried I'm going to be fighting a losing battle here. Going to be away for 3 weeks next month so won't be able to tend to this, would either of the above eliminate the PM now or should I cut losses and just pull her out now?

PsyCLown Posted March 4, 2022 Share Posted March 4, 2022 Yeah, one spray of sulphur or coppersoap should work well. 1 1 Quote Link to comment Share on other sites More sharing options...
Martin7318 Posted March 4, 2022 Share Posted March 4, 2022 I'm finding it interesting how many outdoor grows get PM. Considering airflow is a blaming factor when getting PM indoors. What better airflow than fresh air and wind outside?? How does 1 prevent this? 3 Quote Link to comment Share on other sites More sharing options...

No point having airflow but the plants are dense and bushy, they need to be thinned out/defoliated proactively. Don't water from the top if you can help it, especially during flower. Being pro active with your IPM also helps a lot. I know from previous experience what issues are most likely to occur in my grow, so I prepped for those. (Worms, spidermite, aphids, PM) Sometimes PM infects less resistant strains or weak individual plants. We've got outdoor plants next to each other, the Future 1 has no PM, but the Blueberry right next to it had those same PM spots. I had Coppersoap on hand and sorted that out quick as they wern't in flower yet. In flower I'd go 50% mix full cream milk and water or as was mentioned sulphur spray or pot.bicarb depending on your situation. 4 Quote Link to comment Share on other sites More sharing options...

Prom Posted March 5, 2022 Share Posted March 5, 2022 I join @SkunkPharm with the potassium bicarbonate. If the plant was outside, must be longer as a week flowering by now, we are beginning of March. Copper and Sulphur work.. but don't spray it on flowers you want to smoke at the end. Is not good for your health as some will stay back inside the flower.. isn't good for the taste anyway! Spray that on during flower and you will get very unfriendly tasting smokes. 1 1 Quote Link to comment Share on other sites More sharing options...

Indoors you may have high RH but at least there is no rain falling on your plants combined with the high RH. Preventative sprays for PM and defol can help though. 2 Quote Link to comment Share on other sites More sharing options...

Yeah it has been particularly wet and humid this season here in Gauteng. 1 Quote Link to comment Share on other sites More sharing options...

Seems to be the case here, got 4 plants all in the same soil and area and just one affected. 1 Quote Link to comment Share on other sites More sharing options...
