Anyone else in the have issues breeding Yellows/cherries?

I had good luck with yellows at first had lots of baby's even sold some , then i had a 6 month period of no berried shrimp after months of looking and searching the web i found nothing of much help lots of PH,GH,KH and Temp sugestions tried it all to no avial , Then James0816 made a commit on TDS and it should be around 200 . I checked my water and there it was 600 ppm , so after a week of changing water using my RO/DI unit i got the TDS down to 250 cant get much lower then that now because my GH is getting to low. My Yellows look better and way more active now and the best part they are berried again.

So was TDS to blame, who knows but it worked for me
