oh forgot to mention a big news. fucking i have spider mite problem. i can notice some white yellowish spots on top of plants. and i was able to spot couple mites under some leaves. I purchased a spary bottle in home depot that contains active ingredient : .7% neem oil. I decided to get this one instead of the concentrate, for conveniences purpose. i tried my best to cover everything in the solution. used about 1/3 of the bottle. so prolly used about 3-4 ounces of that diluted and ready to use neem oil solution. Hopefully after couple of application in the next 10 days, we can clear this problem. Soo effing glad i did my hw, or else i would've been FAWKED!!
