Leaf tips burnt; late flower DWC

[Joeykronik]

Leaf tips of smaller leaves on the flowers getting burnt in the mid to lateflowering stage. Some strains worse than others. Using GH flora series nutes in a DWC system. I run my solution at 63F and mix it 50-60% strength. Any thoughts?

Add some straight water or if it doesn't bother you just let it run

It doesn't bother me all that much except I'm kind of a perfectionist. It really bothers the cali weed snobs and they always try to low ball me at the dispensaries

Well not knowing much of anything about your grow I would say flush her to stop any immediate root burn. Some pics would be very helpful if your unable to post the pics go to this link.
