Question about NPK Ratio's

Hello all. If anyone can clarify, agree or disagree to these statements I would appreciate it!

I am trying to figure out NPK ratio's

Basically I added up what was on my bottles which is what I am adding to my res. If I added all these in equal amounts say, 2ml of each per gallon I would end up with 8-6-15. Is this correct?

But this would only apply if I was adding equal amounts of all ingredients, correct? It would change ratio's if I added say 1ml of Silica, 1ml of Calmag then 10ml nutes per gallon.

In that case I would have to figure percentages of Silica and Calmag and then add that to the NPK ratio of the base nutes.
Armor Si
0-0-4
CalMag
1-0-0
Micro
5-0-1
Bloom
0-5-4
Gro
2-1-6
Equals 8-6-15?

What is the perfect NPK for cannabis anyway?
Should I be mixing these in order to achieve a ratio which is closest to what cannabis prefers?

Please reference the picture to see where I got my ratio's from. Thanks!

Your over thinkin it buddy. Start slow

Add your silica first as per low dose on the bottle mix well, wait 15 min

Add your calmag. Mix very well. Wait 10 min.

Add your brown bottle first . Then pink or green Doesnt matter.

Then hydro guard.

I dont know what orca is . I dont use anyrhing except this so far.

Then ph your water to 5.5 to 6

Change your resevoire once a weeek.

Top up with fresh water during the week

I assume your doing a recirculating hydroponic system.... For sone reason.

Hey thanks for the reply. I am going along pretty well but I was bored the other night and was looking at the NPK and thought I would ask!
+1 on the calmag and hydroguard. I use Orca too.

Here they are this morning.
PPM's dropping, PH Stable

As far as top offs. I am trying to go two weeks before a res change. If I notice that the nutrients have gone down say 10%, I mix 10% of whatever my 20 gallon nutrient mix is into 1 gallon of water.

Ppms dropping meats you plants are eating.

I never go two weeks.

Most nute schedules are weekly

So every week your supposed to have a bit more or less so i find it easier to start fresh then to start trying to add back. Because yoir plants eat differently all during the week . You may add some back but you may be unknowingly adding too much of one or the other.

And after a week or so your resevoirs will probably be running the risk of slime and root rot .

Less problems with fresh water/food

I make a fresh resevoir on sunday and just add water during the week
