Npk help with liquid fertilizer

[Pilted]

Nice!
where you getting those NPK ratios ?
Where the 13-23-23 math came from?

For example tiger bloom 2-8-4 at one tsp per gallon, it's requesting 2 tsp per gallon, bringing it to 4-16-8.

From the OP nutes some requiring more then 5 mil per gallon.

Well if you want to go that route you need to convert it to PPMs after dilution. But anyways bottles labels NPKs it's only a guaranteed analysis, it's not a exact number tho. No way to get reaaaally accurate with ppms without the lab batch analysis, you could ask the manufacturer, but will not be the current batch results.

Yeah still learning, right now best I could do with the research I did. I will do a little more research on batch analysis and see what I learn, appreciate the info and will check it out.

What I mean is, don't go too crazy about it, follow manufacturer charts at 1/4 , 1/2, 3/4, full strength? , and adjust accordingly with your observations.
Masure EC and PH if you want more precision and repeatability.

Cheers!

I was putting in 1800-2000 ppm at the 13-23-23, at the 3-14.5-11.1 I was putting in 950 ppm. Runoff I really only check for any big swings not what number it's at and try to listen to my girl when she telling me something. So far been working okay but I am sure there is a million things I can learn to improve growth. . 3rd grow learning more each one. I really do appreciate the info and will do more research on it..

What I mean there was N ppm P ppm K ppm and each element separetly ppms tho. Not the overall ppm witch 2000 (EC 4.0mS equivalent) is ALOT not sure how they didn't fryed with that much.

It's the media, I'm in love with it mycro something or another fungus gathering and feeding my roots. ( or that's what I believe was allowing the high ppm idk my best guess). Idk I'm new but I do really like the media I am using. Pro mix premium moisture potting mix, 3 gallon pot holds two gallon of water. Less watering and keeps leaves on plant very clean.

Aww runoff of organic amended stuff media will have skyhigh EC don't bother reading it lol

After ~3 weeks of flipping to flower just stop using grow big and you will be fine for N for the rest of the flowering there, stop calmag 1-2 weeks before harvest too ;-)

 

[Pilted]

The media, ever since I been using it strange things been happening, like had multiple plants grow branches from the water leaves, never was able to do that from soil ( would always burn the water leaves off quickly in soil). No burnt tips or very minimal. Plant just branches insane from the start. It's suppose to help eliminate over or under watering. Just can't say enough good things about it.

 

[Harpua88]

Well it's water time, and after many many hours researching NPK I have decided a reduced NPK at 3-14.3-11.1 closest I could get to a 1:3:2 ratio. Thanks for the help @ no one.

Oh you think that's funny??

It is......

I think your line of reasoning is spot on. You're however many weeks into flowering, you want to start cutting back on Nitrogem but naturally you want to make sure they get enough of the "P-K". Yeah. I know very little about all of these brands of nutrients, but I do see a general theme that quite often, their instructions call for a little too much/too often. You know this......you say you're lost but I think you got it, it's just a matter of doing the math to turn the dials.

Yeah until yesterday I didn't even know anything about npk and had always followed a feeding schedule. I have a small handle on it now, but I did a lot of reading yesterday.

 

[Bilber]

This leave has me concerned...

@Pilted ....for me....this leaf looks like white powdery mildew....

For a piece of mind, would you check and double check to make sure...

 

[Pilted]

Yeah I will double check it, but I knew I was giving too much ferts I was pushing the envelope. Plus my humidity usually runs 45-50% but in the mornings it does get a little high 55-60%

The light coming through the canopy was giving it that powered mildew look, I pulled the leaves so I could get a pic without the light filtering through the higher leaves.

 

[Pilted]

Like this one looks the same. You have a good eye because I thought the same at one point.

But if I put my hand over the light filtering through the leaves I get this.

 

[Pilted]

While I am here the yellowing on the leaf that showed up hours after I feed a lower amount of N has not advanced as of now. So that's a good sign my actions might be working. Not a 100% that was the problem but still a good sign.

 

[Pilted]

Also the leaves tips curling in has relaxed a little, it is not gone but it is not as bad as yesterday.

 

[Bilber]

I'm truly sorry you pulled a beautiful leaf off....

The one thing that I will go through all resources to avoid is WPM......

Again, I apologize for the inaccuracy......

No, your good, it was my lowest leaf and I have more then I should down there. Your assessment was spot on really it's just the light playing tricks and my poor ability to take a good picture. Never hurts to double triple check and I appreciate the suggestion.

 

[Pilted]

Just an update 2 days after reduced nutes, the leaves showing discoloration is still not advancing ( it will not get better and best possible out come is it doesn't get worse).

The leaves tips curling inwards is still relaxing, it's not gone but I can see they are less and less curled in each day.

And the tint of the leaves seem to be lightening up.

Just in case anyone is following along and is curious on what happened.

3rd grow and still trying to figure out nutes, lighting got it dialed in, temp/humidity got it on point, air flow doing good, nutes i am still learning, seems less is more but not enough is bad, where is that sweet spot. Idk, will take many mistakes for me to find it.

Hopefully others can learn from my mistakes.

What I have learned, don't blindly follow a feeding schedule, do a lot of research on NPK, do a lot of research on what NPK cannabis likes at different stages. Make your own feeding schedule. Adjust this schedule based off the plants reaction. Catch issues early by knowing what to look for.

You can not trust Fertilzer Bottles Directions its a company so they want you to use as much as possible so you can run out and buy more I get the same results with cutting all feedings from the start in half from what the bottle says you can blame the company they just want your money just my opinion
