In a 30 second search of the internet I found both kinds. The question about all of these systemic products is, where is the proof that it is not in the final product? I would rather chuck my plants than ingest harmful chemicals. I know what the labels say, but has anyone proved that their buds were actually safe to smoke?
Also, how are you using the granules? I bought some Evergreen, and have been using it for almost a week. I am not sure if it is working or not, because I only saw 1 aphid in the first place. I hope it works, because it really effected my last plants yield.
I have a question though. I have a plant that is about 5 weeks into flower. She started showing signs of RA's and that is the plant that I saw the 1 on the roots. Anyhow, it is not getting better. It is still bulking up, but the fan leaves are still showing Cal-Mag def signs. Anyhow, should I scrap her, or try to keep her around for another month? Part of me wants to just chuck it, but it should yield pretty decent even with the RA hiccup. Any advice?
Why would you chuck it if it's almost done?
Also, one single RA wouldn't create a noticeable difference in the plant, and where there's one, there has to be more, but it's a light infestation, so no worries. You can use Botaniguard ES all the way through flower if you want. It's a natural biological and not a pesticide. It's 96% effective. Or you could use Bayer Citrus, Fruit & Vegetable up to 21 days before harvest on food crops, so it depends how many weeks your strain is. They call it Citrus, Fruit & Vegetable, because it's formulated to be safe for food crops, and it's a liquid. You don't want to use granules.The medium would also be a factor, but even in soil, a good two week flush before chop would take care of that anyway. Whatever you do, do not use the poison that cyat recommended.
