Ive been having issue with pests. First the thrips then the damn spider mites. Neem oil does not work, and I need a solution that works..
My plants are all in their flowering cycle, week 4, and I am really frustrated dealing with pests. I’ve been spraying 7.5ml of the neem concentrate mixed in liter of water once a week for 4 weeks now, and I’m border line thinking about ditching the plants bc Im so sick of dealing with the pests..
What is causing this? Is it the humidity inside the tent?
If anybody have any advice, I would appreciate it.

Just my opinion, but I would trash it start over cause you've lost this grow.

If you buy soil with pests, you will never beat them. I stopped using Miracle-Gro moisture control for this reason. Full of gnats and thrips and possibly mites.

If you bring plants indoor from outdoor you never beat them. They've already got generations of reproduction on you.

The only way fwd, especially with spider mites is to FULLY sterilize the grow room and tent(s). Then use a growing medium that doesn't have pests in it to begin with, and if your outdoorsy, change your clothes when you get home and maybe even shower prior to entering the grow room.

As a precaution you can always buy beneficial predatory mites.

I stopped the Neem after 1 week of flower, but when you are desperate i can understand the want to get rid of them fuckers, use citric acid, 2tsp per 32oz and spray when lights out every 2nd or 3rd day for like 2 weeks. Gonna change the pistils brown bud it just might save your plant. Dealing with the same issue although not as severe as this one.

Now your buds will taste like neem oil. Same with Safer's insecticidal soap with 10ml/L added neem or canola oil. Soapy buds suck and I know from first hand experience.

I have both those bugs on some plants I brought in from the greenhouse about 6 weeks into flowering. Tried 75% ISO on them and that killed the bastards and dried up the eggs but the plants got damages a bit. I pollinated some buds on each of them so I just want to keep them alive long enough to harvest some ripe seeds but may just kill them so I can give the room time to allow the mites to die off. If there are no plants in there and the room is kept warm around 80F the bugs will all die off in a couple weeks. I can keep everything else in teh veg tent upstairs until they're gone.

I've never tried the citric acid but have some so may give it a go next.

:peace:

Its worth it, plant will smell like a fucking warhead for like 2 days but it works pretty fucking good compared to anything else ive tried at least. If Azamax wasnt so fucking expensive id try that as well but im not that desperate yet lol.

Holy shit. I just looked at the pic. I'm sure you probably have thrips and mites too, but those big white bugs aren't either of those man. Thanks a lot, I need a shower now, :lol:

I know that to be wrong as I've brought big plants in pots into the house but sprayed well 4 times before moving them to the grow room and never saw a bug after that. Lots of bugs including thrips and mites when I brought them in. Wish I'd done that with the smaller ones now but they were 3 weeks into flowering outside already.

there is often bugs in soil especially if there are air holes or tears in the bags and often the bugs like fungus gnats get in while the bags are waiting at the store to be sold. I always tell people to store their bags well away from the plants and preferably not in the same building.

I like about 50% ISO spray too. Works great and I've never had an issue with it. I've actually had more burn with the citric than the 50/50 ISO/water spray.

I keep an eye out for bugs all the time but even more a couple weeks before I want to flip to flower so I can get rid of them while still in veg or the first week after the flip. Safer's End All with the 10ml/L added canola or neem oil kills mites and thrips just fine and I've had to deal with both the last 20 years of continuous growing. I get the 500ml bottle of concentrate and mix my own. Makes 10L for the price of 1L pre-mixed. 4 sprays 4 days apart does the trick for either pest.
