I don't know what to say, things were looking great for so long. I had a defiency that was either N or Mg and I fixed it with FF Grow Big. You mentioned that your veg fert was FF Big Bloom and that you could use it during every cycle. I hope you meant Grow Big, because Big Bloom (as I understand it) is designed for flowering. It is possible for deficiencies to show up after a long time because different plants use different amounts of nutes at different times, so it's hard to tell exactly what the strain's needs are. I think they still look pretty good, though. You have some big buds and some foliage left to support it, so I'm really pulling for you and your ladies. Lots of MOJO your way.
