CalMag burn

[Antonio Bandido]

Hey all,
I got some CalMag yesterday, and put 1ml per Litre of Ph 6.4 water today, sadly the oldest plant in this grow (with the smallest pot) came up with this burn look a few hours after the watering. Did I not dilute the CalMag enough? Is there anything I can do to help this plant out? All the rest of the plants seem fine but I did give this plant the most water out of all of them so perhaps this is the reason?

You should be ok, just leave the CalMag out on the next feeding and go half strength for a feeding or two. Then go back to normal and maybe use a bit less CalMag on that plant. I've noticed that two clones, taken at the same time, may need different things once they are older and rooted.
