First Grow - Sour Disel Auto

The first seedling damped off due to humidity issues. RIP. I've added a few things to help regulate things. -Accelerooter 55 Site Floating Seed Starter Tray w/dome -TaoTronics Cool Mist Humidifier 1/16/21 - Seed popped right out looking ready to grow. I saw a tiny root poking out the bottom and transplanted right away into a 2 gal. fabric pot and watered with 6.8pH until I saw water draining out the bottom. 1/17/21 - Second set of leaves has shown up. I've got a moisture meter in the soil to help me get a feel of when to water. 1/18/21 - Things are looking good. night temp gets down to 65F and humidity is staying consistent. Light is 14" away from the leaves. 1/19/21 - Givin about 1 L of water with 3.75 mL Big Bloom. My last 2 sourD seeds popped out of their root plugs so those girls into 3 gal pots filled with ocean forest and water with 6.4 pH @73F and I have those sharing the space. Thinking about purchasing a sf2000 really spice things up. 1/21/21 - 3 sour diesel are now chuggin along in my space, "Jim", "Dwight" ,and "Eloise". Water Quality -I learned that my tap water contains chloramine which will not evaporate so I'm fighting that with some 100% ascorbic acid using this spreadsheet https://www.reddit.com/r/aquaponics/comments/1qpumz/here_is_a_water_dechlorimination_calculator/ and my local water quality report.
