BF Purple punch - Main line experiment

Pretty sure what you've done (recalibrated, flushed) will help but don't expect the damaged leaves to look any better because they won't... When you give plain pH'd water, always water them enough to get runoff and check the pH of the runoff.... and try to maintain a pH between 6.0 and 6.5 ... as they get into flower, you're going to want to aim for the sweet spot of 6.2 .... Good luck!

I did a slight flush and readded some nutrients, but focused on more calcium and magnesium. Ingoing ph: 6.3 Outgoung ph 6.3-4 I Also moved the light a little further away. Thank you very much for the answers!
