during mid grow, i added some dolomite lime to help balance the ph. ive been giving it tap water that naturally runs ph 7-8, and runoff water has been 5.8. i ruled out bugs because my other plants don't have these brown spots. i think its either maganese or possibly calcium deficiency? i notice these get brown spots spread when it give it a feeding with fox farm trio for like the 5th week of flowering feeds. if anyone has experience these, please help a brotha out!
