On my second grow, going alot smoother this time around thx to RIU cpl more ?'s

I am having some great results with the lucas formula...my question since the formula is set at 8/16ml/gal does the ppm remain the same throughout? I always thought I am supposed to increase the nute schedule as plants grow

Next question is to top off can I just use the 8/16ml /gal and top off my buckets? I have been reading and some say just to put in RO water but won't that dilute the nutes? Why not just mix the same solution and top off?

So if I need a gallon to top off my bucket just take some distilled water mix 8/16ml of lucas and then fill back up. Am i missing something? Thx all

P.S. I moved and cant find my camera usb but when i do i will post some pics

You top off with ro water to avoid overfeeding it. Youll find the plant drinks more water generally so it concentrates the mixture more. Topping off with ro water is the best way to keep a fairly steady ppm level.
