Manganese Deficiency?

So tomorrow will be week 5 of my flip into 12/12 and I am having trouble diagnosing what is wrong.
Soil is FFoF with a bit of their basic planting soil throw in (3:1 FFoF to Top Soil)

I usually feed 1 day, wait 2, water 1, wait 2, feed 1. ETC,

bobcajun, you should stop posting in this forum as it's clear you have no understanding of what you're saying. You're learning the buzz words that are frequent here, "precipitate," and "locks up," and "deficiency." These words mean nothing if you're wrong. Any substance precipitated out of soil is going to be useless. The grower is 5 weeks into flower and can't wait months for a solution. The idea of deficiency in this grow isn't accurate. If you'll read the first post you'll see how much fertilizer is in the soil. Too much. You don't want calcium to precipitate out, for whatever reason using whatever methods. The fact that too much phosphorus has been given (because for some reason the grower thought this would be good), far outweighs the effect of calcium or magnesium or Sulphur, or any other "deficiency" you people like to discuss. At least you're not hanging onto the idea of pH like what took place years ago. 10 years ago, people in online forums were always saying "dude, check your pH" all the time. It is fertilizer content that drives pH. Adjusting pH in soil is a waste of time. If you put too much fert in your soil, it will drive your pH down and you must get the excess fert out rather than adjust pH. The only real solution is to avoid using too much fert to begin with. Foxfarm soil already has fert in it. You probably don't need to add any more. Read the labels, email the company, and find out how to properly use their products. Following the instructions is what you want to do.
