So we're a couple weeks into flower now. I finally got my hands on a ph meter. Our water has a ph of 7.8 but with nutrients comes down to high 6s. Runoff ph was 6.3ish. I'll keep an eye on it the next few feeds and see what happens. Found a little caterpillar that had been munching on my leaves, no eggs that i could see so hopefully not a prob. Had a couple weekends where I've been away and girl has dried out a bit between waterings but she's held up under the stress ok.
