So here are the pics...
First: The middle "do nothing" two plants #1 and #2
Second: The small blooming plant #3 that is losing all it's roots and leaves. Looks to me like pseudomonas which I did treat

but nevertheless may be a gonner.
Third: Two of the larger plants doing well #4 and #5.
I notice on the picture as well the PrimeAgra with the whitish specs. I have read this can be residue from chemicals although I have not used any in weeks except on #3 just today. I have also read this can be due to improper washing of the PrimeAgra. However, not only did I follow instruction but I have washed through this media multiple times since then and ONLY use bottled distilled water from the market.
