Fuel D. OG

She has been fairly easy to grow but I have some kind of deficiency going on. Either Magnesium or Phosphorus. I've been giving it a lot of fertilizers for each and it seems to be helping but hard to tell because the old leaves still look bad. I'm just paying attention to the new leaves and they actually look like they have nute burns. It's kind of frustrating, hopefully this Bud turns out really good and worth all this trouble.
