I got a Co2 meter and my levels are pretty high I think, averaging around 1000ppm when I'm not in there and spiking to over 2000 when I am. It doesn't seem to be bothering the girls so I'm not too concerned just yet. Watered with recharge then a few days later with silica, both at about 6.5 ph, both were well received. Transplanted to 5 gal fabric pots at the end of the week in same soil mix as last transplanting with 12tbsp gaia green 4-4-4/pot.
