About of lucas formula

Hi,

I have two bucket, each bucket 5 gallons, my needs below:

Veg (0-5-10): Grow=0 / Micro=25ml / Bloom=50ml
Flower (0-8-16): Grow=0 / Micro/40ml / Bloom=80ml

- Which period I add nutrients add to water?
- When should I refresh bucket water?
- Can you give a example 0-8-16 addback method?

Thanks,

lucas formula is only using flowering nutes throughout the whole grow... Not sure what you are saying either
