I have what looks like mag def. People keep telling me to use more cal-mag plus, but I have read that its cal that can cause lock-out, and mag def...Is this true?
I am planning on flushing. My girls are in veg, and I was going to make the switch to 12/12. Should I keep them in veg, and flush or move them to the flowering room, keep the lights out, and flush..or any other options.
Also would a 3 day flush work? longer?
