I wish I had a camera so I can ask this question properly with a picture so you can see what I am asking but when I was in the grow room I set my camera down while I was getting the plants that are showing the problem out and I stepped on it .
Anyways what I am seeing is on the oldest leaves which are yellowing and the tips are dry and brittle also these yellowing leaves are showing a brownish discoloration at the point where the leaves join the stems. My ph from my run off is around 6.6-6.9 the only other thing I can think of is that with using RO water if it could be a deficency of micro nutrients like cal or mag but not really sure.
