apparently, it stops lowering the kh and ph when its done cycling. until then all i need to do is keep the NH4 from going above 2ppm, and ph below 6. NH4 was 1, but i already put in baking soda 2 times and the ph dropped to 6 again, so im doing a 100% WC to get it to stay ok for the night (tap is 7.6, and after i add baking soda it goes only to 6.2).
the good thing about this is that it gives the plants a quick start. the constant WC and leaching of organics gives them all the nutrients they need, and the low kH makes the CO2 dissolve easy, so my levels are a bit higher then normal.
