question for experts...wierd trend

I grow in readygro aero formula. I use supernatural nutes. 5.8 to 6.0 ph....I use nutes every watering perhaps too much ppms....everything looks awesome all the way through veg but about two weeks into flowerthe leaves start to curl and tips look burnt then a few days after they start to look like they got way way way over nuted....could I have been over nuting the entire time and it only shows up during flowering?

Sounds like salt build up....needs to be flushed...its good to give it plain water every 4 watering

yep sounds like you have a lock out. first flush everything down and start with fresh water. DONT feed her until the lock out is fixed. and after shes recuperates give her nutes but at a 1/4 strenght in other words something very light. it might take a few days to a couple of weeks for a full recovery.

agreed with the others needs to be flushed, and try no to feed untill shes fixed

So I did a epic flush like you guys said like 3 days ago...it helped with the yellowing but im get dead patches on the leaves now....im in 15 gal pots and put 15 gallons through them...with this 50 perlite 50 aero mix I shouldn't get root rot so are these dead blotches and leaf death still a part of lockout?

Need to add cal-mag
