Pool Shock, Calcium Hypochlorite is the easiest way and what I used when running NFT.So did a bit of reading on different types of root rot. Looks like that may have been the culprit. The yellowing may have been because the roots were coated and not getting enough nutrients. Eventually, they were coated entirely and the pant stopped getting water.
The air tube that goes into the top of the bucket MAY have been letting light in. Plus, it was getting warm from time to time... So..my next step is going to be preventing root rot. I can block off the opening where the tube is with electrical tape etc. But how do I keep it cool? Also...is Hydrogen Peroxide the best way to prevent future blooms and...if so, how much/how frequently?
Again, thanks for bearing with me as I stumble my way through all of this.
You need a pH pen and a TDS pen to run hydro.
