Turns out my inline diffuser was clogged. I work 9-5 and workout from 5:30 - 6:30; my CO2 is only on from 10-6 pm so by the time I get home my lights are on but my CO2 isn't. Well, today was my off day and I came home during my CO2 period and my bubble counter was going at 2 bps and there were little to no micro bubbles coming out of my outflow. I'm sick of this GLA inline diffuser, I have cleaned it every other week and it's a pain. I instantly switched to my nano disc diffuser and cranked the CO2 up from 5:15 - 6pm and instantly all of my plants (with the exception of the DHG) began pearling like no other. Let's hope this counteracts the melting and stops all BB algae. So disappointed.
