your reverse osmosis water has all the cal/mag removed, you need to add that back into the res with calmag+ or another similar product. You may have some other minor def working there, but with adding the calmag you should knock out alot of that stuff. While your at the store, i would also look at a micro nute just to be on the safe side (it wont hurt to have it handy if you need it).

From what i can see in your photo's your missing Cal for certain. I personally try and solve one problem at a time, that allows me to dial into the problem more accurately. Just my opinion, but i am sure there will be another post coming shortly.....
