@Pochogrower, Thanks! No, I don't water in between feedings. When I run Coco the plants always get fed with nutrients until the final 1.5-2 weeks when they get flushed with r/o water only. Generally, I will feed based on what the plant needs. Some need 2L every other day, some need 1-1.5L every other day. I will switch it up and do larger feeds when I feel the plants need it to flush out any old salts or possible build up. For example, 1 time per week I will up the feed to 4-5L so there's plenty of runoff.

@TheCrippledChicken, sorry for the late reply here. Thank you for the compliments! If you are able to add Co2 then yes absolutely do it. My run was without added Co2. I was simply exchanging out fresh air while outside temps were acceptable for my rooms. Now with it being summer weather, I'm having to run the AC and add Co2. Regardless, if you are able to seal your rooms and add Co2 you will always benefit (especially in flower). I would run Co2 in flower at 1000-1200ppms. That's just my 2 cents from past experience. As for 1 more week of flush... I don't think it would improve much. 2 full weeks of flush has always had yielded great results on my end.
