I have a question about the lucas formula, specifically this method:
1. "Top off the reservoir daily using a pH corrected water solution as required to maintain full reservoir level. After adding back an amount of water equal to the amount of your reservoir capacity you should change the reservoir and put in fresh solution. "
So the bucket holds 3.5 gallons, and you top off with pure water with no nutes every day until you've put 3.5 gallons of fresh water in, wouldnt this cause the PPM to be too low? You dont replace the buckets NUTES until you have put 3.5 gallons of pure water back in, im thinking once you have put in like 2 gallons of pure water into the original solution (as time goes on and the plant drinks and water evaporates etc) you will get nutrient deficiencies? and the ppm will be quite below what it should be..?
very confused... (i did the lucas formula with the other method, topping off 100% every day and it really did not produce healthy plants)
I feel like im missing something....
OR is that what the addback calculator is for? says its only for advanced users though
Appreciate any help/clarification blades ! Thank you in advance!
