Attempt at Water Only BuildASoil

Week 3- What I did - Transplanted into the final pot, a 27 gallon storage tote. lots of drainage, BuildASoil recipe, plus Clover mix cover crop. Watering at 10% water by soil volume, so roughly 3 gallons, every ~6 days. The Good - plant has really taken off since the transplant + light defoliation. its grown ~ 3 inches in a matter of 2 days. The pictures may not show it, but that's because I pulled the top 2 branches over with more hooks. The Clover has sprouted, and the soil is staying moist for far longer than I figured. EDIT: I'm also seeing a good about of Fungai cropping up onto the top layers of soil, which if my knowledge holds true, is a good sign! The Bad - I'm seeing a PH reading on my in-soil meter of ~7.1. I've moved it around just to be sure, and double checked with run-off. So when I watered I PH'd to 6, and the run-off read 6.5 on the pen. I'm a little concerned the mix came out too Basic, but we'll see moving forward. Going Forward - Honestly, I'm considering topping a second time. All of the branches are working on their 4th nodes, I've got the time to let it fill out, and I could end up fully filling out the Scrog net if it goes well. Thoughts?
