Nutrients/Watering/PPM/

Your plants are eating just fine.

On 5/16 your runoff was
Plant #1
PPM= 1843
Plant #2
ppm= 1690

On 5/20
Plant #1
PPM= 1280
Plant #2
ppm= 1250

I would push the happy frog one more H2O water feed with a hit of 175ppm of calmag as followed…

Plant #1
Measure your
Water source = XXX ppm
Then add calmag (very little at a time) until the ppms come up another 175ppm mix well. Just before you feed them pH your feed water to 6.5
Document both your feed and run off numbers.

Plant#2
Measure your
Water source = XXX ppm
Then add calmag (very little at a time) until the ppms come up another 175ppm mix well. Just before you feed them pH your feed water to 6.5
Document both your feed and run off numbers.

After this H20 calmag feed you’ll be ready to start feeding your girls at approximately 1/4 strength of your nutrients feeding chart recommendations.

Continue to demonstrate persistence in good watering practices. (Let that soil dry).

Right On!! I will go do this know and post numbers.

On lowering the light the manufacture recommends 18", although I do agree it could be lower. My concern is burn, what is an acceptable leaf temp? 80deg?

What would you use as an alternative?

After you do this morning’s watering your next will be required nutrients that you supply.

There’s a guy who owns our local pub that does total organic. Were in a water community and there’s several seafood restaurants crab houses etc.

He collects from the local restaurants fish parts, crab shells ect and turns them into nutrient amendments.

My oldest son has tried his weed and said it is quite smooth but couldn’t really see a difference in what we grow and what he grows in taste and or harshness as ours was just as mild as his.

I know of all the nutrient lines out there Fox farm is known to be one of the saltiest.

I always had luck amending our our, bone meal, Alaskan fish heads, and so on. I will have to dig in the archives to find our old recipes. I never watched any of this stuff, as for the numbers.

OK< Report-

P#1
PH=6.5
PPM=1150
P#2
PH=6.44
ppm=980

All right your numbers look good. I do want to address a few things to you.

First off is your water issue. @Myfriendis410 recommended looking into an RO system I can’t agree more. You are totally depriving your plants of good nutrients having a PPM beginning at 400.

Example
Let’s say your plants are eating at 700 PPM per feed. Your feed starts with the PPM of your water. Over half of your feed is whatever is in your well water. Actual nutrients is 300 PPM and we haven’t even begun to add additives which will raise the PPM.

This is not a good thing. Can you do it? Yes. We are plants thrive? Not really.

Other options

1.) An RO system that hooks right up to your sink you can pick them up on Amazon for about $90 bucks

2.) buying distilled water directly from Walmart by the gallon it’s about $1.25 here per gallon

3.) Water filtration Banks. Just about every grocery store has one. You can fill up 5 gallon buckets for about $2.50 here. Make sure the unit has an RO filter or it’s guaranteed distilled water.

4.) collect Rainwater. I did this on my first grow yes it was a pain in the ass but the plants loved it.

5.) continue to do what you’re doing with well water (not recommended)

Addressing your second issue. The nutrients that you’re using is Fox farm trio. I’m not sure if you’re new, if you understand or not on feeding so I’ll assume this will help you. if not, then disregard this…

Let’s go back to the original scenario. You have 400 ppms of feed (it’s your water) now you have to come up with 300ppm to reach your desired 700 PPM feed. Do you know how much to use of each product? Of course you don’t.

So what do you do. Look at your manufacturer’s suggested feeding chart and feed at 1/4 strength???

Well if you did that your ppms would be somewhere around 4216 (that’s a little bit over your 700 required).

I’ve got a little exercise that helps you understand how to you small amounts to get your desired ppms. This exercise will help you understand how many ppms are in 1 mil of each of your nutrients. This will allow you to mix your feeds 100% easier and actually know what you’re putting in your feed.

The products and numbers below are examples. You will simply plug in your product and your numbers to give you the correct numbers

What you’ll need is one gallon of water, a syringe that measures ml/cc etc…

First understand the numbers below are example numbers just to show you how to do the process…

All it takes is measuring and adding.

First you take your gallon of water and you measure your water in ppms or EC

Water = 75ppm
Now add 1ml of calmag that takes it to 225ppm
So 225-75 = 150ppm
That tells me that 1 mil of CalMag =150ppm

So far our mixtures totaling 225ppm now we add 1ml of Micro
That made our feed jump up to 290ppm
So 290-225 = 65ppm
That tells me that 1ml of Micro = 65ppm

Now our feed is 229ppms
We’re going to add 1ml of grow
That made our feed jump up to 312ppm
So 312-229=83ppm
That tells me that 1-ml of grow =83ppm

Now our feed is up to 312 ppms
Now we add 1 ml of bloom
That made our feed jump up to 384 PPM
So 384-312=72ppm
That tells me that 1ml of bloom=72ppm

And you just simply continue adding 1ml of any nutrient and/or additives that you have to this feed to get the total ppms and you’ll have a calculation of what 1-ml of each individual product you have is equivalent to in ppms

Now when you have 400 ppms to start you’ll know that you need a little of this a little of that and you’ll know the numbers and how much of each product to get to your 700 PPM desired feed…

Good example buuut what about dry nutrients?

Good question I never used them

@Lostgirl — This is helpful in terms of understanding your technique.

Could the dry nutes be handled in the same manner only measured as dry? It seems that would stand to reason.

Love this thread!

I I have never even seen dry nutrients other than amendments. I would need more information on the nutrients and how they’re used. It could be amended into the soil in that case you’re just going by a weight and not necessarily a number that’s crucial as PPM.

The dry could also be added to water. This is why I say I would need to actually have the product, and how to used.

Anything can be figured out. It’s mathematical for the most part.

Thank you!! Really good explanation, of which I will mimic on next feed and yes you are correct I am new to the trio. No wonder I was getting nute burn, and they have not needed a feed. Looking good today Though!! Starting week three FLWR, defoliated the rest of the LARF. P#2 is still showing some slight burn on the tips…

IONBEAM-4X4-500W Full Spectrum. 18" from top cola. Changed light intensity from 8 to 10 today.
P1-PPFD=1156
P2-PPFD= 1531
RH=47.5
AT= 78.9
VPD= 1.43
Question? Do you think I should drop that light down from 18" to 16"? If not, Why? & If so Why?



I’m not a big light person. I bought the best light that money could buy that I could get in 2 days when searching for a light. I ended up paying $700 and the light will flower anything in my 4x4 no matter where the hell I put it. I don’t use the apps I just do what the recommended manufacture setting.

With your light the fact that you’re in flower the manufacturer suggest 12 to 18 inches from the canopy. Apparently this is what you’ll get at 100%

It looks like your girls are sativa dominance which always grow a very long main cola that far supersedes the rest of the canopy in height.

You asked me what would I do and why
If those were my two girls I would put the light at 16 in at 100% however, knowing that I had sativa dominance with extra long colas I would tie the cola off to the side of the tent by simply bending it over with a piece of wire or string. This will allow your plant to share the benefits of a real 16 in.

Why 16 in? They recommend 12 to 18 I figure you can’t go wrong in the middle :+1::partying_face:

This is how I tie my plan off when the cloas are too high…

@Lostgirl — I see the wisdom in your thinking. I will lean more heavily on the math-based approach to which you subscribe. In doing so, I will develop my own feeding schedule and modify it as needed.

As always, I appreciate your counsel.

By the way, thanks to your advice, my most recent grow was the most successful of the three I’ve done. There is still room for improvement, but learning is part of the journey!

I knew you would do just fine!

Gosh, I really appreciate the Mach up here. Feeding in ml is much easier to understand as well as controlling down to the cc of how much of each nutrient you want to inject.

Today is feed day! Below are my calculations based off your example.

Starting H20- PH=7.65 ppm=0 cm=0

Nutriments-

1ml-calmag=68-ppm

1ml-Big Bloom=81 ppm

1ml-Grow Big=140 ppm

1ml-Tiger Bloom=211 ppm

Adding Second ml of each.

1ml-CM=282 ppm

1ml-BB =295 ppm

1ml-TB =350 ppm

1ml-GB =413 ppm

Adding Third ml ea.

1ml-CM=472

1ml-BB =485

1ml-TB =536

1ml-GB =603

Final fourth ml ea.

1ml-CM=744PPM-Final

1ml-BB =613

0ml-GB =N/A

1ml-TB =674+ 1ml=680

Final ML=

Cal Mag-4ml

BB=4ml

GB=3ml

TB=5ml

Based off of Fox Farm-conversions chart for soil feeding.

1.25ml=1/4tsp.

Final Feed- PPM=744 PH=6.5 cm=1564

RUN OFF & ppld @ 16” from canopy.

P#1-PPM 1380 PH 6.3 cm 2270

P#2-ppm 1140 PH 6.40 cm2270

Ppld-1046

Leaf Temp-79 deg

AT-79.8

RH-45.1

VPD-1.47

Staked down P#2.

Will give just straight H2o @ 6.5 next when they show they are ready. It has been 2-3 days normally. I am still a little concerned with the final numbers on the ppm on P#1.

Questions?

At what point in the flowering stage should these numbers be coming down? Am I to continue with 700ppm feed until I plan on doing a Straight water flush before harvest?

5/24 marks day one of week three flower here.
