I have no idea how that got into this thread? I was seriously posting it in a totally different thread and I'm sorry.Hey Sq
Looks like you've done good so far! I used to do dwc, but switched to Coco because of the heat issue.
I didn't see any where that you're using anything to help protect your roots from high temps. Real important in the summer. Many people use 30% food grade h2o2, I use sm90 and there are other brands and types like res clear. You should get something ASAP. It also doesn't hurt to have some half litre water bottles in the freezer for extra hot days, just drop one in each bucket. For future grows look into silica in your nutrient line.
I like the liquid koolbloom up until about the last 10 days of flower and then I switch to the dry koolbloom for 7 days and then a three day flush. I think the three-day flush is all your really need with General Hydroponics Flora series.
If you go with SM 90 go with 2 mil per gallon. It will protect the res from buildup of anaerobic bacteria a big threat during hot Temps. It will also help the plant uptake nutrients better. You'll find all your plants look better within two or three days of beginning it. It's also a good wetting agent and can be used as a foliar feed. It will stop powdery mildew if caught early and sprayed directly on the leaves in a dilute solution. They actually used to call it spider mite 90 because it is a bit of an insecticide. Anyway I guess I promoted that enough for now.
Hope you don't mind all the advice I think I'll sub up if that's okay?
