Brown Red Round Spots on 4-5 Fanleaves / fungus ?
Budz_Bunnystarted grow question 10 months ago
Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be?
I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.

Puede ser un hongo o quizás también quemaduras por algo que le hayas aplicado foliarmente con las luces encendidas o salpicaduras del agua de riego, yo eliminaría la parte que esta dañada y ver como responde el resto

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.3 years ago

What deficiency is this?Can someone tell me what this is being caused by? My suspicion is a potassium/ calcium deficiency? It's affecting mostly the larger fan leaves. Also, affected leaf stems are turning purple. Posted a pic of one of the leavesWeek 6
