cap i need to pick your brain for a minute . if everything seems to be running in harmony can you tell me why you fell the need to make weekly or biweekly change out ?
i start making weekly change outs at about week 7 as i start dropping ppm's . i use CS nutes .
thanks
If it ain't broke don't fix it. Do your thing!!!
I change weekly on habit. Been doing it for 15 years or so. The old hydro rule is that you should change the water when the plants have drank 2/3 of the capacity of the system. Could be an old wives tale or a general rule of thumb...
I am no expert. I think if you can find a balance you have nailed it. You may want to look in to biofilters or even bags with washed lava to place in the epicenter. This will give bennies something to colonize. They will need a food source, so if you are using CS you will need to also add a small amount of molasse.
What I would do is crown feed full strength only at first enough to saturate, maybe a cup or 2 per site. See where that takes you.
You may want to ask desert squirrel or UCMENOW or someone with more experience in changeouts, or even CC. I know on the bottle there is a recommended dose for weeks 1-8, which to me implies a weekly changeout. Unless you have sophisticated sensors and can monitor individual ppms of NPK Ca etc.. its kind of a crapshoot to know what the plants are using and what they arent.. IMHO
