Hey @gmslave you may have actually answered the question I have out there about my grow. I have light green leaves on a 3 day old seedling and was wondering why. I was targeting my ph for first two ferts at 6.2 ph for CalMag absorption because I don't know if Mother Earth is pre-buffered for CalMag. Tonight she gets 5.8 ph target. I think this is what is happening to mine and your comment helped me see that. Thanks.

Your ph is set for dirt, lower your ph to 5.5 to 6.0 for veg , 5.8 sweet spot in coco and 6.0 to 6.5 In flower with 6.2 to 6.3 being the sweet spot. Cheers

Soil pH is surprisingly high. What's the best/safest way to lower soil pH (without eliminating nutrients from dry amendments)Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?
