Just started adding terpinator and herculean harvest to my nutrient mix last week and I just noticed some yellow spots on one of the plants. Could this be related? I only gave one low dose of both nutrients along with botannicare pure blend pro, cal mag and silica. They just whey into flower room last week as well. So lots of changes. However these spots only showed up on one plant. Curious what it is? Sent from my SM-N920V using Tapatalk
Looks like a pH issue to me. If you correct the pH it won't correct the current leaves but it will stop the problem from spreading. Here is a ref with some other pics for you..... http://www.growweedeasy.com/ph-fluctuations-cannab...
