flush until your run off is a 6.0. dry you pot out for a few days, resume everything but use less nutrients

How is about ppm? Be careful if you have hard water on your site... Maybe try with 50-50 RO 💪

Need help identifying the deficiency hereI just started seeing some kind of deficiency on the lower leaves of my plant that's still pretty young. Can someone please help identify? Just tested the PH and it's at 6.4. I'm not seeing any spots on new leaves. Do I ride this out? Do a flush? Appreciate any advice!Feeding. Deficiences

Yellow leavesmy little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST)
it could be due to the flushing done (but less than 5 days ago) 🤔5y ago
