PH rise, EC rise, less water usage

Give me the name and associated ingredient percents on the back and I can do the hydrobuddy for you. They did it for until I foynd a pc to borrow since all I use is a phone.

This could be quite difficult to write bcs - there is some "analysis" title on the bottle, but when you look at those ingredients inside (also written on the bottle), you will see that there are some difference. Not every substance contained in is in the analysis. Especially when I look at one part of 3part basic nutes, there are just nitrogen and potassium in the analysis. But in the "derrived from" column are: potassium nitrate, magnesium sulfate, magnesium nitrate, magnesium amino chelate, nitrogen amino chelate...and amino-acids. So why is no magnesium in the analysis?

I ended up getting them online but don't really know how to use liquid correctly in the program.

Hey, @Skybound420 you know how I go about using liquids correctly with hydrobuddy?

 

[Skybound420]

To add a liquid, do everything as you would for adding a custom salt, check the Liquid checkbox which opens a new field. Density is discovered by dividing the weight in grams (kg) by volume in ml. Both of these measurements are on the front label, on the bottom. 1 liter of 0ppm water weighs 1 kilogram, so if the contents weigh 1.1kg, there's an extra 100 grams in the bottle. 1100 grams / 1000ml = Density. I think you need to set the Concentration Type to A or B, but I had no issues when combining salts with liquids when playing around with various things.

I had difficulty tracking down the contents of AN, so good luck.

 

[shawnery]

So it's as simple as 1.3kg or 1300g weight in AN divided by 1L or 1000ml,

Exactly back to the original weight?

I guess that's the advantage of liter bottles.

If a liter weighs 1300 grams, the density is 1.3.

I did everything step by step the same as yours except I calculated mine in ml.

On a side not if you stop using the two extra bud liquids your down below 10 for mg which is really not good.

You're going to have a deficiency really quick. At the very least start using those again.

 

[Skybound420]

You can enter all of the nutes you have recorded, then on the main page input your targets and calculate that way and get a much more intentional feed solution with the store bought nutes. I did that with GH when I had those profiles, but the result wasn't all that close to the ratios given with GH's feed schedules. But just the same as we tweak our salt supplies, you can do the same thing with liquid nutes and hydro buddy.

 

[shawnery]

That's how I did it.

 

[foliage2018]

Just a quick questions to my thread:

Might it be an overwatering problem? I read about Mg,Cal,K nute-lock when you flood them too often (especially on a long term)? Could slight overwatering each day cause this? As long as Magnesium is key-element to photosynthesis, then the plant is consuming less water?

Is it even possible to overwater plants in flood and drain when flooding every 2h (cycles takes 26min)?

 

[5BY5LEC]

If you had an issue with oxygen at the roots(under/overwatering), it would wilt. It would be obvious.

 

[foliage2018]

Actually they are wilting in the lower part (big fan leaves). All leaves, not just these hurt by deficiency. Higher leaves look OK - not wilting.

I also realized I removed about 20% fan leaves that were shading bud sites a day before it started to show some problem in the res tank. But I didn't change the flooding frequency.

I tried to change flooding frequency today. So we'll see tomorrow.

 

[ANC]

Don't ever trust what the bottle says... I can show you photographic proof that Flora trio has about 1/3rd less nitrogen in the bottle than it says on the label. Yet it still manages to over nitrify plants.
By law all our fertilizers have to be tested and the numbers printed on the bottle or added by the label if there is a discrepancy.

 

[shawnery]

Your doing to much at the same time!

Pick one thing and try it. See the effect and move to the next logical step.

Your connecting things that aren't connected like removing fan leaves and feeding schedule, although I don't grow your style.

Have you put the two bud additives back in because your mix requires those from my calculations?

 

[rkymtnman]

^^^^^^ this.

try to change one thing at a time or you'll never know what makes it worse or better.

 

[foliage2018]

I am trying to find the reason why all this happened. That AN base mix has to have enough Mg inside bcs when you start to grow until flowering, there are no additives which contain Mg and the plants are not suffering.

1-2 days before all this mess happened I've done few things:
1. Removed some fan leaves (about 20%)
2. Speed up my exhaust fan (lower humidity and lower temp)
3. Applied neem oil as a foliar spray

I thought that the decrease in humidity will force the plants to drink more water (it should), but I didn't realize that less leaves and lower temp can cause the opposite.

All that was very fast, from the first sign of issues, it took about 5 days to the death of maybe another 15% leaves. I need to be quick in mind as in actions.

your big bud is the problem

you need to get a nutrient calculator and put in the values of what your mix was AN 3 part with big bud and post what your NPKCaMg ratios are.

too much K will lock out Mg.


if AN nutes are as good as they claim, the 3 part is all you need. no additives.

 

[foliage2018]

Those 3part basic nutes are Potassium rich on themselves. Big Bud is just 0-1-3 and 50% dosage in comparison with basic nutes.
And there are other additives AN is offering in their line with potassium content.

But I will follow your recommendation if the previous steps will not work.

You have hydrobuddy, right? If you can would you double check my numbers for him? I have pics of all the bottles for the numbers as well.
