<span class="link_user">@MRTHC</span>, I'm growing organic, too. I use coco coir, perlite, worm castings, crab meal and kelp meal, mycorrhizae and trychoderma, and I haven't had a grow where I can forget about pH yet; maybe that's the case for super soil though. For this strain I'm between 5.8-6.4, never above 6.4 and the plant is doing great. If you're using soil maybe don't go so low, but do try to keep it between 6.2-6.5 and see how it responds. N shouldn't be an issue even at 7, so maybe it's just the plant genetics with the color; mine also looks a lighter green, but it's growing super strong and fast and lower growth is also the same color, so it's evidently not defficient in anything.
