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?
oh and lighting is 2 24'' t5 garden lights, 1 24'' LED, and the 150W overhead grow light. And I half dosed the Master A&B on the feed a couple days ago.
Here's a picture of my best plant, about 2.5 months old right now. Yours look great IMG_6237 by Creed Bratton posted Jul 15, 2017 at 5:28 PM
It's growing fine.. though if you don't have a ph tester I'd at the least go to the pet store and buy a ph solution test kit... plant foods dramatically change water ph so it's best to ph it back to around 6.3 or so before watering. Robs New Journal RQS SQ#1 Clones
Also because I'm unsure of the strain I don't know how large of a pot to finish in. I believe it is a sativa dominant strain so should I stick with a 3 gallon ultimately or should i just go straight to 5 gallon?
this was my plant at around 3 weeks from seed. It's tiny as you can see, ignore the early topping. Your plant will take right off soon, it'll grow quicker than you know what to do with
