I saw there were some request for more info about the failing seedlings. I am using black Gold potting and raised bed soil 0.07 0.03 0.03, under a vivosun VS2000 (200w) grow light. I got a new pH meter and ppm meter and mixed the nutrients the way I have been. It came out to 875 ppm @ 5.61 ph. I added a 1/4 teaspoon of baking soda bringing it up to 6.7 pH. I also took the advice of putting a plastic bag over the cups to hold more humidity. I am now running a humidifier in the room. I don’t know if they can bounce back but I am going to do my best and learn from the experience. Also are jiffy starter pods or pucks good or bad?
Thanks for the straight feedback on my last question,
