First kick at the can

Things are going okay. It looks like I've got an issue with something along the edges of the leaves, besides a bit of light stress, I think it's related to high pH in the Promix because I'm usually 6.2 going in and once in a while 6.3. I am gonna let my last few waterings drift towards 6.1 or 6.0. I finally got a PPM meter and I gave straight water March 25 around and when I checked a 20 mL sample of the runoff my meter was flashing 2000. Being curious, I added RO water which was 6 PPM until I could get an actual reading and I ended up adding 60 mL to get a reading of 700. That's telling me that there are lots of nutes still in the soil and gives me a good bit of knowledge for my first grow. Round two is already on deck😋
