UPDATE
Day 57 today. She keeps slowly filling and frosting up, and I've been increasing nutes to see if she gains back her green colors and stops yellowing. Some roots are starting to show up in the tray which is a first time for me in the Autopot and which I love since root rot is my main fear right now and that doesn't seem to be the case this run.
On Saturday I bumped the feed to 1.4 EC / 700 ppm (70 tap, 560 mc, 40 cmp, 30 be), pH 6.09 (6.2-6.3 in trays), and today seeing her still yellowing and with no tip-burn I prepared new nutes and bumped them up just a bit more to 1.47 EC / 735 ppm ( 75 tap, 600 MC1, 30 cmp, 30 be), ph 5.98 (6.1-6.2 in trays).
Light is still working at 60 Watts and it's positioned 21 cm / 8.2 inches from the tallest top... providing there a DLI between 37-39. RH and temps still the same.
Here are some pics taken today a few hours before lights out:
