Bud discoloration after using neem/nicotene/pepper/garlic spray.

Hello all,

The sprays were not all at once. I used nicotene/garlic oil/ pepper a week ago and neem 72 hours ago.

My buds look discolored-light brown. It does not extend onto the leaves and is only on the outer portion of the buds. The inner portion looks as it should.

Also, the hairs are brown. It is nearly ready to harvest. It is a Nirvana Afghani.

If the plant is dying from thrips-would it not mature just a bit faster? I think I read that cold might also hasten ripening.

I have had cooler temps in the effort to eradicate the thrips. The buds look ripe and I think I will chop tomorrow. Just got a sample drying at the moment.

I'm not sure the concentrations you used but sounds like could be phyto-toxic burn.


Not sure if this applies to garlic oil (or all oils for that matter) as opposed to horticultural oil (which is a petroleum based product for ornamental crops only-NEVER USE ON CANNABIS) but they say when applying horticultural oil to use the 140 rule. The 140 rule is you add the temp and the relative humidity and don't apply the oil if the sum is greater than 140.
So 70 degrees F plus 70 degrees RH (or 80F + 60RH, etc.) equals the threshold to not apply the oil.

Also, spraying any kind of oil under the hot, intense light of an interior grow light just seems like a "frying" could take place.

But I think it was the combo of products, concentration of one (or all) and the frequency at which you applied in your particular setup that allowed for the phytotoxic burn. I've seen pepper spray burn plants and I also wouldn't want to smoke any bud that has any sizeable concentration of nicotine on it. You've gotta dilute that shite big time before application.

Yeah, but I did not just spray them and put them back under a hot light, I had a fan on them and the cabinet door was wide open. They were dry in 20 minutes - I was actually surprised at this. I attribute this to the fan.

I only used 1.5 cigerettes in a cup of water and brewed it int he micro for 5 minutes to kill the mosaic virus (or tabacco virus) and then deluted by half. It was not that strong-was actually thinking of upping the concentration for the vegging plant as they seemed to tolerate it fine. It could be the plant is just dying from thrips.

The leaves inteh buds are a dark bright green (as they should be) but the buds look like they are dying.

I have dried th e sample from earlier and I have smoked molded weed and I did not taste it tonight. But I did taste the tale tell sign of no cure (yuck - chlorophyl).

Just keep in mind cigs aren't nicotine only. Who knows what the tobacco company adds to them at the processing plant. But I doubt it was the nicotine/solution that caused the damage.
The brown hairs seem like a sign but since they were ready to be harvested maybe it was just that that variety turns "rust" when ready.


Whenever I think about concentrations for pesticides I try to relate it to my size. If I was covered in a nicotine solution of 0.75 cigs and absorbed it into my skin all at once I'd probably freak so just imagine the size of a thrip being dosed with 0.75 cig. It's all about amount of dosage to body weight, like the DUI charts. lol

i recenty used a similer spray for spider mites.. hav'nt got rid of them all but really helped the plants get back to health.. in a few days i'll use bug off.

anyway i used four roll ups worth of rolling tobacco in 500mls of hot water, a drop of eco friendly dish soap & chrysanthemum flower heads wizzed in a blender and strained.

this worked a treat on my mums but on rooted clones (2" tall) it fried them... and im sure it was the tobbacco.

Yeah, I would agree with you on the concentration.

I have been reading further abotu nicotene spray and the number of smokes seems add up to about an ounce of tobacco-a pack maybe to a quart of water an then delute by half.

I am going to water cure them so it snot hat big of a deal with regard to residuals as they will be removed by the water.

Its more to the point that bugs are phvqving up my yields, and as I have read others to say ~ "I needs me spinich" .

And as it turns out, they might not be thrips at all-they were not ID'ed at the local hydro shop.

I am likely going to chop her tonight anyway to make room for more.

I am also going to open up a NPS in addtion to neeming them tonight.

Before you release NPS (dichlorvous seems like a scary word to me) you need to id the bugs so that you can target their poison. post a pic. IMO thrips are not that common of a bug.

Thrips are one of the most common insect pests in the USA. There are several new varieties like the chile thrip and the citris thrip that are very hard to control. Nicotene is about one of the strongest insecticides used in agriculture. It has been outlawed for years. In case you guys have not figured this out yet, the way to control thrips is early when plants are small and vegatative. Thrips do not just "kill a plant". They are more likely to give your plants a virus that will kill them. The virus could be Tobacco Mosaic or any number of other viruses. The Thrips pick up virus from weeds and then spread it to crops.
