Solid posts here. Make sure you keep your PH in that nice middle range. 8.5 is high, but I dont see it killing your plants. But if you're really trying to get these buds as dank as possible, then it's a bigger issue. Dank bud is all about getting the maximum effective dosage of nutrients to your plants as efficiently as possible, and PH levels can really have an effect on that.
