Some of my older leaves are/were doing the same exact thing right now, also at 4 weeks into flower. From what I understand its a nitrogen deficiency, I upped the amount of N and the newer leaves are way greener.
Something also tells me the problem may lie with the roots. I was very root bound and once I transplanted the problem seemed to go away... You mention some slime and brown on your roots which I imagine could be what's causing damage. Hopefully someone who grows in hydro can come along and tell you how to take care of that, might be as simple as cleaning out the res and sterilizing everything with peroxide

Never thought of that m8. How did you black the tubes out seeing as they are underwater??

Not sure I understand m8. The tubes are covered over as they go into the rez. Do you mean the parts of the tube that are going into the chiller and exposed to the lights when they are on BB?

Ph seems a slightly high for my likings. I try to never go above 6 in hydro. Just my 2 cents. Try keeping it between 5.5 and 5.9

H202 or dutch masters "zone" will help get rid of that root slime. I'd recommend keeping a live or sterile Rez.(active bacteria or something to kill all bacteria, good or bad) One or other. Each has it's own advantages.

PPM is referring to TDS (total dissolved solids) readings. IMO it should be used in correlation with EC (electrical conductivity).
Edit: sorry I thought you had said you didn't know what ppm was, not what the specific ppm was. Excuse me
