Pictures and Transpiration

Well I topped off the system and it went from about 4.5" to about 6.25 inches and a CF of maybe 29 to 32 in there somewhere to a CF = 18 so I added a cup of concentrate and it's now running around CF=23. So the question is: How long can I safely leave the system without topping it off and changing the nutrient ... as the season continues the interval gets shorter and shorter unless you get a slug of cool days.
