Thanks! Ya, the Tangies are doing really well. I don't track TDS at all... I usually don't give anything but water for a few weeks, but since they have a very limited window to live, I like to push the limits with nutes and light.
I have 3 regular and one XL sized Exhale bag in the tent, plus I dissolve about 10 x little CO2 tablets in a jar of water in front of the intake fan every day. I only check the CO2 ppm's once per day right after the lights and fans turn on and it's usually 1300+, but that drops to about 950-1000 once the vents are all going.
