aren't both you guys using longer tailpieces than the 6" ones i use?
where are you guys measuring from? The base? I prefer to use centimeters myself...

until we find what is wrong try drilling a 1/8" hole high in the top sidewall of each of the plant reservoir buckets.
right under the rim where water shouldn't be anyway. try one first and see what happens.
Rather then drill anymore holes in the lower modules I think I'm just going to wedge a quarter or something in between the lower and upper modules to give me a small gap for air to enter.
you will not be able to achieve chemical stability anywhere in the system until you solve this hydraulic issue.
my flower res and the whole floor part of the system was at 970 ppm and ph 5.9 this morning right before lights off. this is with an input of approx 690-730 ppm, which includes my 110 ppm tap water, so the jack's part is right around 600 ppm.
i have run this initial filling with only input for almost 10 weeks now
as i have loaded my room with more plants each week it has been getting more stable. once all plants are in place, 10 plants a week apart, the whole system will just sit there and run at a certain level for months.
this is because of the continuous blending and re-blending of the solution. if there are hydraulic problems this is not occurring properly.
so i think increasing ec to correct ph could exacerbate the problem.
i never had these issues in the same brand coco and the same nutes you are using so this is a mechanical problem. something is not flowing right.
mechanical problem causes roots to sit in too wet conditions.
which causes anaerobic activity and some organic die off each time.
causing plant displays and slow growth.
breakdown of organic material causes ph fluctuations.
again causing plant displays.
when you fire the pulse, do you ever stick a yardstick in the res first to get the starting level and then time how long it takes to return?
if it takes more than about 10 minutes somethin' ain't right.
I've been watching the system more closely lately and it appears to be functioning fine. Air-gaps are being maintained and I've not see any further issues, making me think that one bucket was a 1-off blockage issue from existing gunk in the lines. (these return lines are re-used from a DTW coco grow)
Picture Update - few days after the flip.

My favorite one. She's getting pretty massive.
