New Grower Advanced Nutrients pH Perfect 3-part GMB - Need Advice

[Hansbricks]

Hello AFN,

I'll be starting my first indoor grow soon, I decided to go with the AN pH perfect nutrients since I'm a newbie and didn't want to worry about adjusting pH all the time, plus it seems to get pretty good reviews. I'll be using the 3-part G-M-B, not the 2-part Sensi G/B that most people seem to be using (local store didn't have that).

Does anyone have any experience with this that can give me advice and/or a recommended feeding guide. From what I understand (correct me if I'm wrong) I'm supposed to use all 3 in equal ratio in both veg and flower stages. So should I be using around 1-2ml/L of each for the entire grow?
(FYI, my grow medium is pro-mix organic with amendments)

Also what water should I use with these nutrients? I've read that it works best with low ppm water. My tap water is like 370ppm so I'm guessing this is too high. My other option is to use 0ppm RO water, would this be better or cause other issues?

Welcome To AFN Hansbrick :stylez rasta smoke: i would use the AN nute calculator here http://www.advancednutrients.com/hydroponics/calc/ ..i'm a Sensi user i just did a review check it out ,you can get a good idea from there on how and what to feed

also if you have any more question just use the same post ..no need to start a new thread i see you have two now , it makes it hard to get you the help you need ..:stylez rasta smoke: and also it helps to introduce your self to everyone else here a link for that

good luck with your grow and welcome to the family

From what I understand (correct me if I'm wrong) I'm supposed to use all 3 in equal ratio in both veg and flower stages.

Yes, unless you're planning to use the Lucas formula, you'll use all 3 equally. I recommend doing that.

So should I be using around 1-2ml/L of each for the entire grow?

The chart says 1ml/L for seedlings, 2ml/L for small plants, and 4ml/L for mature plants. It's usually smart to dial that back a little to be safe. It's better to risk underfeeding than overfeeding.

Also what water should I use with these nutrients? I've read that it works best with low ppm water. My tap water is like 370ppm so I'm guessing this is too high. My other option is to use 0ppm RO water, would this be better or cause other issues?

They recommend RO water for the pH Perfect nutrients, that's what it's guaranteed for. However I've heard from people saying that it works great with their tap water (others say it doesn't work with theirs). So what I recommend is to try it with your tap water first. Mix a small batch up and see if the pH locks in where it should be. Then let it run aerated for a few days and see if it stays. If that seems good, try it out with your plants and still keep a close eye on it. It all depends on what it is that pushes the ppm of your tap water up. Some things wreck the pH Perfect tech, some don't.

Tangs feed schedule is stickied over in the soil/feterilzer section I believe. He grows some monsters with it, you should definitely check into that if you're going to use the line.

I can help you however you need a ppm meter as your base ppm seems very high.
Mix in the following order, Micro then grow then bloom then any additives after that eg silica, calmag, big bud, overdrive etc

With a starting rate of 70 ppm tap water using an USA calibrated ppm meter
Seedling early veg stage - 1ml per liter each of AN micro, grow and bloom get you approx to 350-400ppm
Veg to early flower stage - 2ml per liter each of AN micro, grow and bloom get you approx to 700-750ppm
Flower stage - 2ml each of AN micro, grow, bloom, AN Big Bud 2g power per liter get you approx to 1000-1100ppm
Late flower stage - 2ml each of AN micro, grow, bloom and overdrive per liter get you approx to 1100-1250ppm

maybe consider running 0.5ml per liter of each during seedling and early veg stage, 1ml of per liter of each during veg and 1.5ml per liter during flower to prevent nutrient burn and keep your ppm levels within the above ranges. I would keep Big bud and overdrive at full strength as the instructions list.

Maybe some of the more experienced guys will chime as maybe with your ppm levels i might be wrong

good luck

You can usually get information on your local water chemistry/quality from your water supplier, which will tell you the normal range of the relevant things like pH, alkalinity and hardness (I expect these will be the main issues that could affect the pH in a buffered nutrient solution), it will probably also give you the conductivity (you would probably call this ppm). It's normally easy to tell if you are in a hard or soft water area. If you do find that your water is unsuitable for use with the buffered nutrients you could always try blending it with deionised water to bring it into a more suitable range. The recommendation by Knowboddy2 to try it and check the pH over a period of time seems like the most sensible approach. If you know the alkalinity of your water the suppliers may be able to advise whether or not it will be suitable (trying to guess this from conductivity sounds like a very vague way to do it).

The ppm of your tap water is way to high to use with the AN nutes. They recommend it be in the 100 - 125 ppm range. So it looks like you'll need to use the RO water and add enough cal/mag supplement to raise the ppm to the proper level, then add your nutrients.

Thanks for the input guys. I've almost completed my second grow now using these nutes but I still have some questions/comments. I've been using RO water and have been adding 1-2ml/L of cal/mag first then the micro, grow, bloom and any supplements in that order, mixing in between each one. During my first grow I believe I was running into pH problems, lockout etc. So I started checking the pH of my feeds for my second grow, what I noticed was that if I don't adjust it is in the 5.4-5.6 range which seems really low. I end up having to add like 15-20 drops of pH up just to get it to around 6.0... I don't think this is normal, what value is it supposed to buffer to??

 

[Muddy]

In my experience the pH Perfect will usually stabilize between 5.8 - 6.2. You may not be adding the correct amount of cal/mag. It's almost a necessity to have it in that 100 - 125 range in order for it to work correctly. A meter that will measure the ppm is almost a must when using these nutrients.

 

[Hansbricks]

So if I need to add more cal-mag to correct a deficiency would I initially just add enough to get starting ppm in that 100-125 range then add base nutes then add additional cal-mag after?
