been searching on DWC nutes and this is the main thing that keeps coming up. Also does did a lot of reading about root slime/rot... which I seem to be getting now. I have always used R/O, botanicare cal mag, flora nova grow/bloom w/ GH feeding chart, sweet or bud candy, white shark, and prozyme in a recirculating dwc. I always get great quality with these so im weary to switch nutes. Well recently I went to the store to get more cal mag and they only had gh cal mag which is organic/fermented molasses. I reluctantly bought some and bought sub culture b&m cuz thats all they had and added it into my recirculating DWC. I have been out of white shark n prozyme for quite some time now but until now have seen no problems, I just havent wanted to mail order any nutes n been short on $ but I found one with a great return address. Well I added the gh cal mag and the sub culture according to the directions and then started to get the root slime...went back to the store bought more enzymes thinking this would clear it up and no it made it worse. After reading about root rot and slime I am realizing by the end of flower I usually have a lot of brown roots. I use to think the nutes I used just stained them until I read about organic material in dwc. So I am now thinking of switching my base to technaflora because my local store carries it, its specific for hydro, and it keeps the water clear or colored not brown. For the past 2 weeks I have been cleaning roots using h2o2 no brown nutes or enzymes, only adding sub culture b (to keep water clear n monitor roots) and it seems to be clearing up after it killed a tub in transition stage.
So should I switch nutes all together and stay away from brown water or just stay away from the gh cal mag which I think started the whole black slime root problem. Really just want more peoples opinions about DWC nutes before I switch. What is the best recirculating DWC nute? Are full-synthetics better than organic or semi-organic? Do you get the same results using no organics? Will changing your nutes negatively effect the taste or production? Is it best to use nutes that keep you water clear not brown in dwc? Can organic nutes cause root rot in dwc?
