Hi everyone, so I have a couple questions, firstly I’m confused on nutrients, the adding to water part that is, can you just pour your new nutrients into your RDWC res after taking out the dirty water and adding in fresh water? I know some people use a separate res but I don’t know if you have to which is why I ask. Also, when adding nutrients, say I’m in the flowering stage, and I have a few different nutrients I want to use in my flowing stage after I’ve just put in a new batch of water to my RDWC, would I have to juggle through my different selected nutrients and leave out some to keep my PPM in check? Say if I added in what I wanted, and I have one more type of nutrient that I want to add, but my ppm is already ideal, would I just leave what else I have left to put in out? I’m a bit confused over this and it’s the only thing holding me back at this point in time. Some help with these questions would mean a great deal. Thanks everyone and I look forward to hearing from you and getting some more knowledge over this topic.
