Help with Plants... cal mag?

here is my first scrog one month into flower ph is 5.8 stable and ppm is 1400 buds look great leaves not so much, any suggestionswould be appreciated thamx. I just added cal mag 2 days ago for the first time...I have used ro water from day one

Looks like nutrient burn to me...hard to tell from the pics being so far away...

if using a tds meter at conversion .5 I gueguess 1400 ppm is really high... 300 ppm of that is cal mag though. its a learning for me at this point ....do you think the buds will be okay or are they going to be cooked as

Drop your levels. I bloom between 700-800ppm. 1400 is really hot. You'll save nutrients and your plants will be way happier.
