I battled spider mites for almost a year.. tried many products along the way. This one did it for me. I would use this if you're in veg up until week 1-2 of flower if needed.

Especially if you're still in veg and don't have to worry about the pistils getting a little browned. It will kill them and the eggs.
Yea, just getting started and will be in Veg until late July / early August approximately
Citric acid and vegetable oil. You can either mix it together yourself or pay $35 for a 16 oz bottle already mixed. Either option will work.
And there's the man who taught me about citric acid,
What does the vegetable oil do? Does it act as a carrier oil or something? I haven't added that before but I'll try it next time if it helps spread out the love to the little bastards.
Yes sir I always do. I have a Hudson Atomizer and this thing sprays a 10-15 foot fog that envelopes the whole plant for all directions.
I've never added oil when I use citric acid. I do use oils as a preventative. I'll make a mix of potassium silicate, canola, and a little sesame oil as a foliar to use as a preventative against insects and PM. I prefer sesame oil over neem as it doesn't stink and it's a dual use product since I always have it on hand for cooking. For an active infestation I've just always used straight citric acid mixed with water.
Which one do you use? We always have a small bottle of the toasted sesame oil.
Are you just using food grade citric acid powder? If so, what’s your ratio per gallon?
Yes just food grade. 2-3 tsp per quart is the standard dosage. Some people have said that 3 tsp cause some leaf burn. So starting with 2 tsp per quart is advisable. I think various factors affect how strong you can make it. Temperature, humidity, light , etc... Indoors it should be sprayed with the lights off and plants allowed to dry before turning the lights on. Outdoors it should be used like other foliars and sprayed in the morning or evening but never during the middle of the day.
Okay, you said Citric acid and vegetable oil and I thought you were mixing the two of them together. I have always just sprayed the citric acid on in water with a mister and had great results as far as killing the bugs. I thought maybe mixing the oil did something different. Thanks for clarifying my misunderstanding.
I was referring to the PureCrop 1 which has soybean and corn oil along with citric acid. From what people say that product is effective. But I think it's mainly the citric acid.
My guess is the citric acid kills and the oil prevents any ones left alive from sucking on the leaves. It probably helps keep the citric acid moist so it works longer too.
. I have no idea if I'm even close.
