Because the GrowFAQ from OG (repeated on many sites and by many people) is wrong and says 0-5-10 is for vegging.
Lucas recommends 0-5-10 for flowering under low-light conditions. We're talking T8 and T12 Fluoros here, possibly lower wattage T5's? If you're running 50wpsqf with CFL's you're going to want closer to 0-8-16.

Would you elaborate on the maintenance you're having to do? Been using Lucas with R/O for a decade without issues.... several different types of setups.....
Whatcha doing and what's the issue?
Jumanji2: I've used hardwater micro with lucas. Once bought it by accident and had to use it for a couple weeks.
Used it with R/O water and the timing couldn't have been better. Had been growing in DWC and the plants had gotten a bit too big for the screen height I'd designed.
The hardwater micro (in R/O water) without the calcium allowed the plants to get really soft and rubbery.... bent them under the screen and tucked em all nice without breaking anything. Got the regular micro about the time they started to suffer from no calcium.
If your tapwater has enough calcium in it... with little else, I would say try it. Personally I prefer R/O water as it provides reliability and repeatability like no other water source. I've lived in crappy water places my whole life and I've moved a LOT.
