I grew hydro tomatoes in my greenhouses. Every hydro nutrient chart I saw showed a gradual decrease in ppm's. I grew the Farmtek system and they also suggested the same. Although nutrient companies stand to make more money, considerable amounts of it too by suggesting feeding full strength to the end, and enjoying a better experience by doing so(they want repeat business?) they continue to show the same on their charts. Farmtek continues to decrease nutrients towards the end of cycle for tomatoes.
they taste awesome off the vine with any nute system I used. the ones I would play with and feed to the end- bigger, greener leaves, longer finishe to ripeness and a taste like a freshly sprayed golf course.
feeding my hydro mj to the end makes for
1)Heavier vegetable material at the end
2) really pretty leafy flowers
3) late finishes
4) off tastes unless fermented in jars for months maybe
5) at two weeks drying smells like my lawn after fertilizing
I dont grow for magazine pics or for heavier weight(vegetable matter, not more thc btw) .
I've had cured weed, months in a jar burped, its fine, but it was not fine 2 weeks after drying.
My weed dries for a couple weeks and tastes perfect out of the gate, no fermenting, no burping, no burying in dirt,
no soaking in water, and my stable finishes on time with solid milky trichs and a hint of amber on the horizons.
my tobacco tastes sweet ater dry too, imagine that, no wood smoke, no fermenting, no sweating, no fuss.
I notice outdoors in my orchards. Plants are provided with less resources as their season ceases. The fruits ripen during this period, less light, less nitrogen less frass, cooler temps, and no added fertilizers. they taste great too.
I can taste off fert flavors in my basil too if I feed to the end but not when I dont.
FLUSHING with water in the end likely does nothing but suffer a plant in its end stages I agree.
I feed chick shit every couple weeks until the last feeding before harvest. My run off ppm is barely changed at this time compared to biweekly feedings. Of course hot nutrients remain in the mix, just not freshly added ones is all. flushing wont apply to my grow habits unless I am using a hydro fed system, and I never would run plain water at the end. theres always a weaker ppm on the chart suggested though. (they losing money left and right?)
doc who does not feed to the end btw.
