I am not argumentative I am opinionated. Pumping liquid with no nutes just dilutes and stop chem reactions. You can pump up the ppm levels with a good sys but you get less. I had my bp up at 1600 ppm and peaked at 1800. I noticed I had healthier grows in my aero systems. Krusty was past his peak when he was with the kbser's(the whole 3 weeks he lasted) Tomato growers can pump up the ppms. They have thousand of cycles under their belt, They are not running 2 day flushes. You want your plants to tell you what to feed them. When you lose the yellow/green growth in your top shoots you have done something wrong. Most need to just back off on the ppms to get the color/growth back. I call it chasing the gold. Krusty's main premise was no stressing the plant. I do not see how yo-yoing a plant like that caused no stress. Look at the flowers you have seen that look and taste the best then, look to the grower. Ask him what he runs. The growers I admire the best all use lower 1000-1200 levels. A constant level feeding program is best for a plant in my experience. Pouring a bunch of crap in for 5 days then taking 2 to get rid of the excess does not make sense in my experience. Now if you have some beaster that shows explosive growth and has that color and you are feeding it 1600 ppm I say go for it. I just have not run into that strain yet.
I run my nutes till I have replaced 90% add back. That is about 4-5 days in flowering with a reserve of 4 gal per plant. Every other week unless my plants tell me otherwise I will flush my buckets with 5 gal for pH water.This has nothing to do with the levels inside a plant. After the rinse and spray I drain and fill my rez with a new batch of nutes. No change in brix or pH in the plant. Any of you have a refractormeter, or a cardy pH flush your plants for 2 days and look at what happens.
So I gave you my opinion on that argument and a way to test and disprove my theory.
I have killed many plants not being a blind follower, but I have learned a few things from my school of hard knocks. I always have more then 1 rez running in my room so every grow is a side by side experiment of some sort. Suerte JK
And for that cheap shot deadheadfred I encourage everyone to build their own if they need to save money, spending hours doing so. And I have not spent a dime on me from my tanks,all proceeds go back to my patients.These tanks have helped me grow free for 2 years, and we thank those who we have helped along the way.
