@ghostdog, hey again. Here's some basic 101 stuff you probably already know but helps to revisit sometimes.

Mobile elements:  nitrogen, phosphorous, potassium, magnesium, and zinc. Typically develop visual deficiencies in older leaves.

Immobile elements: Sulphur, calcium, iron, manganese, chlorine, boron, copper, molybdenum, sodium, silicon, and cobalt on the other hand develop deficiencies in younger leaves first and progress down. 

Bacteria: that inhibits a plants growth are surprisingly common. The plant itself might show symptoms of many different deficiencies at once, this is because the bacteria is obstructing and/or consuming nutrients that the plant needs. Symptoms may include PH dropping or rising more than 1 within 12 hours. 

I like the visual charts too, hope this helps.     peace

If that’s the only area affected could it be how close it is to the reflective material? When my tent was full the first leaves to go “off” looking were touching the sides.
