So I tried some Sensi-zym this time around. It's my 3rd indoor grow using DWC. The first two I used just Sensi-grow/bloom with no other additives. Had no problems, everything stayed pretty clean. On this grow the only thing that has changed is the addition of S-zym. Now there is a brown residue lining the walls of the rez. Doesn't seem to be causing any problems with PH/EC so I'm wondering if this is normal or not?
