I'm glad I use a 396gph pump, that must be it. Oh, but I run 80sec on and 8min off. Oh, and I have had a100% success rate for years now. Now you have seen someone that does it and I could show ya about a few hundred more people who also do it. This is a proven fact, running a smaller pump constantly will raise the temp more than a larger pump on a timer, I have tested it. Running multiple totes from one pump is easy, and less to have problems with.
agreed.. was thinking going this, not sure you remember squid, but he got 40 on his runs, sam wattage, same power, easier to build
After you do a run with less light and you are still having problems, bite the bullet and buy a couple big jugs of purified water and do a run with it! If you are still having problems, that will eliminate water as your problem!

Are the stems rotting or are the leaves dying on the ones that do not grow roots???
