How low before topping up res

I have two areas. One veg thats a drip system in a 2'x4' tray emptying into a doubled up rubbermaid res. I am using GH Nutes 3pt and 10gal of water. I use a stick that I marked in one gallon increments to determine how much is left and do a daily check. I usually add another gallon when it gets a gallon low.

How low do most successful growers let the res go before adding more water?

I will soon be cloning and moving the vegging plants into a flood/drain flower room, using a 3'x3' tray and hydroton with net pots containing plants in Rockwool surrounded by hydroton in the pots as they presently exist in the veg room. I will let the clones veg and flower the more mature plants, getting rid of any that turn male. I will be using a larger doubled up rubbermaid in the flowering room and use 20gal of solution. I plan on creating a marked stick to measure the res using 5gal marks up to 15gal and then going in one gal increments from 15-20.

How low should I let this res get before adding more water?

My 10gal res typically uses a half to a gallon a day. I expect the flood/drain will use even more per day.

Well I got no comments on topping up questions. How about the nute load on the added water. I have read that some just top up with water to res change and others add nutes to their top up water. How do most of you do it? I just added a gallon PH'd around 5 since res is higner between 6-6.5 PH. I think the rockwool is raising the PH.

Iam getting antsi to clone and put the mothers in the flower room. I tried to get away with exhausting into vented soffets but I think most of the hot are was not flowing out and was juct being trapped in the room. I my separate building has on air or heat but does have a massive amount of electrical connectins. I told my contracter that nothing pissed me off more that having a all my wall outlets blocked. My room is on for seperate breakers with
ll0Amps available at the breaker box. So, I removed my canfan exhause hose from the soffet and cut a whole in the bottom of the room that will exhaust under the buildingl I have a baffle box built abound the can fan wth fiberglass and insulation in a can inside with the
