Using Lucas Formula @hydro(bubbler) - minimum waste protocol?

Hey!

I have 70l tank for 2 Banana Kush's, EC-meter and I'm using GHE nutriens with Lucas Formula.
LED 400W (Bloom -setting)

I wanted to ask your opinion for nutrient adding protocol;

Started with 4 week old vegged plants at 70l reservoir; 2:1 Bloom:Micro [EC 1.8]
-> they liked it; growth and visual inspection OK - EC didn't jump up or down noticeably
After 2-3 days I added 20l water + 2:1 B:M [EC 2.3]
-> they liked it
After 2-3 days I added just 20l water to give them a little rest from high EC [EC 2.1]
-> they liked it

So, my question is, can I continue adding nutrients with this kind of method as long as visual inspection and EC are fine? I also keep PH levels checked, been around 5,8 ... 6,3. I would like to waste as little nutrients as possible and flush the tank only if problems can be seen / metered.
