As far as the RO water, I am a plumber so that's no problem but the amount of RO water I need would be a problem as the household systems I have installed would be lucky to provide enough in a week....
Yes there is a max of ppm's. The plants will let you know by dieing if you over fert.... Think of ppm's as a nute strength guide. Little plants need low ppm's where larger plants need more. Some strains can handle more ferts than others so tracking ppm's is a great way to know how much your plants can take before the affects are negative. I used to push 1800 ppm's the last week of flower before flushing, but this is me and I knew the plants could take it. 1800 btw is really high for ppm nute strength, I only recommend going this high if you know what you are doing......

If you were to get a 40-55gal res/tank, you can have the RO flow on a line filling the res/tank on a floating valve. It might take a week for the res/tank to fill but you only need it once a week. I'm sure you'll have no problem running a water line to your grow area where you can connect the RO filter and tank. Shoot, you could even put it in your veg space if you split your flower tent in half....Just to keep it out of wondering eyes view....

If you'd like to pick my brain, just ask away....
