Was going to do another week of veg but it was starting to outgrown my space so I decided to just switch to flowering. Flushed with about 4-5 gallons of 7 ph water, though runoff was stuck at about 5. It doesn't seem to be affecting growth. I gave it a few waterings with water that had a few TBSPs of baking soda added as I heard that was supposed to help raise soil ph. I also further reduced the concentration of nutrients by another 25% (now 37.5% of original recommended amount), as well as reducing how much nute water it got. Didn't see any new nutrient burn after either watering with nutrients but there's now a strange coloration in a few of the smaller, new branches' leaves. This doesn't seem to have affected growth either. Also got a hygrometer/thermometer so I could accurately keep track of those things instead of guessing.
Nice one
