Yellowing & Browning Leaves.. HELP!!

im startin to notice some deep yellowing and a lot of brown burn type marks..

the stem of the plant is a strange red color.


what is going on?!


Please help!!

You could have sulfur deficiency but i would need to see a picture of the plant to know for sure.

+1 for sulfur

Sulfur and/or Magnesium deficiency can be easily taken care of with epsom salts.

Add Tsp per gallon, or a heaping tablespoon per 5 gal

these are real bad brown marks..

like almost orange looking.


i flushed them completely with water, they look slighty better but still kinda yellow...

what is going on?!
