PS. Having grown 2 to 4 plants per 20 gallon containers I will never put more then 2 per 20 gallon container and I will train them away from eachother. DWC has explosive growth. I was given a 4 plant 20 gallon bubbler and it was a dissaster, even after flowering immediatly from clone.
then you have other issues...the easiest way to have a consistant ph level is using ro water. Now I don't know what nutes you are using, but It is a lot harder to have consistant ph with tap watrer due to impurities and metals squewing the ratio's, and causing reaction's that in turn change the ph

I have absolutely no ph problems at all in drip, or dwc or any method using ro water. Now I use 3-part...and always will, So I cannot say about other nute formulas:smokin:
