anyone know what is the proplem on this plant, i grow in soil. plz only the top fan leaves, the lower one I did burn them with very close light. the new growth is suffering from something, could be a nuterient lock , the yelowing started from the base as u can see and affecting between the veins, also the main stem got red stripes. what u think is it Fe,Mg,Sulfur,Zn?? my ph runoff is 7 i tried to to flush with 5.8 ph to compensate and i got to this proplem and my ph still 7 though. any thought would be appreciated.
