What Def is this?

  1. I have a hard time believe it is nute burn since I am very light on nutrients. 1 in 9 had it two weeks and then 3 in 9 have it now. Harvest is quickly approaching so I don't see it getting corrected in time. Mainly just to tickle my curiosity. I have seen it before, but can't remember the cause. Pretty sure it's because I stopped filtering my water and just use air blubbers for a couple days. 

  2. Looks like a magnesium deficiency from filtered water but I have no clue what you've been feeding her. CalMag? 1/8 teaspoon of Epsom salt per gallon of water, but look into it, don't just take my word.
