2 Fast buds blackberry autos inside a 3x3 tent with a 4” carbon filter and oscillating fan.
Light: Mars Hydro TSW2000 running at 25% (approx 30,000 lux)
Average temp: 75 degrees
Average humidity: 45%
Fox Farm Ocean Forest mixed with Happy frog soil. “Water only” living soil was mixed in the bottom 2/3 of pot.
This problem started about a week ago and has been spreading pretty rapidly among my plants. Haven’t had anything but issues this grow. I also had this issue on my first grow but never found out what the issue was. Can anyone help identify the problem?

- looks like Ca defc. to me, very common indoor under LED's,.... I'm also dubious about the in-pot pH considering the soil brand; 
soils are very iffy, OF especially, #1 problem soil I see in here hands down... often very acidic, poorly composted, full of garbagey bits... Too acidc, and Ca among other nutes, can start to lock out...
