I began from seed just under 3 weeks ago. I just completed my first flush following my first feed 3 days ago with the master A & B from humbolt nutrients. My pH has been consistently high around 7.5 but the foliage has actually been looking healthy in my opinion. Haha but if I knew what I was doing I probably wouldn't be asking. Avg temp: 77 Fahrenheit Avg Humidity: 58% I feel like I must be doing something wrong. I've seen other people's 3 week old plants and they are almost a foot tall! Is it nutrient lockout because of the high pH?
