Hi everyone
I use soil farming
It is dangerous and difficult for to buy fertilizer So I use easy to get

A.Vegetables 20-20-20 + trace elements （Fe 3.8mg / L. Mg 3.3mg / L. Si 7.4mg / L. N 97mg / L. Na 41mg / L）Both powders 6: 1 mixed

B.Flower 10-30-20+trace elements
Both powders 6:1 mixed

Currently used ppm
Vegetables
1week-250ppmA
2week-500ppmA
3week-800ppmA
4week-800ppmB

Flower
1week-1200ppmB
2week-water
3week-1500ppmB
4week-water
5week-1800ppmB
6week-1800ppmA
7week-water
8week-water

Is there any better way to use this deployment?

Thank you everyone

First off welcome :slight_smile:
secondly during flower weeks B should be primary nutrient
The products you describe are quite strong in ratios so another way to use would be as needed 1-2 feeds during veg 1-2 feeds during flower

Sorry I do not understand what you said
needed 1-2 feeds during veg 1-2 feeds during flower
Can you explain in more detail? I’m sorry I do not have good English, so I can not understand some words translated

You should only need to add fertilizer
week 1 A
week 3 A
week 5 B
week 7 B
Unless your plants show they need it more
it’s almost 01:00 here so expect delayed replies

The ppm I hit above is a bit wrong
Correct for the current ppm

1week-350ppm(A)
2week-350ppm(A)
3week-800ppm(A)
4week-800ppm(B)
Flower
5week-1200ppm(B)
6week-
7week-1200ppm(B)
8week
9week-1500ppm（B)
10week
11week-1500ppm(A)
12week-

This is the current formula that uses fertilizer and ppm

So my current recipe Well two weeks fertilization will be better?Other time did not fertilize water only?
I am worried about fertilizer ppm excess or deficiency

I’m sorry my question seems a little more please also forgive me thank you

The ppm on your feed weeks looks decent

6-800 ppm B
By week 11 you want to see reduced ppm

Thank you
So flower 1week(5week) is 1200ppm
6week-11week is 800ppm right?

9

correct that would be my goal points
