What happens to a plant that is fed more P&K than N at each phase of the grow cycle?

Yeah, that and the HP seem to be what most people use. The HP has very little charge, and I start feeding after about a week with a mild .2 to .3 EC solution. Also, I follow the notion not to treat it like soil but soilless.
Yup I mix them
Just having a hard time following op with his version of promix
My bad

This is the mix I'm using (or planning to use) https://www.promixgardening.com/en/product/detail/promix-premium-organic-vegetable-herb-mix it's comprised of these ingredients
  • Canadian sphagnum peat moss (60-75%)
  • Peat humus (except 2 cu ft comp.)
  • Compost (except 2 cu ft comp.)
  • Perlite
  • Gypsum
  • Limestone (for pH adjustment)
  • Organic fertilizer
  • Mycorrhizae - PTB297 Technology
  • Coir / coconut fibre (2 cu ft comp. only)
It says it has organic fertilizer, but it also claims to feed for three months. I'm not too keen on believing that it will feed for three months based on my experience with using their seed starting mix. Therefore, most of what I need is already in the mix aside from the nutrients which I plan to add (and I have enough on hand as well).

Is there anything else you need clarified, or that I might've been not so clear about?

Nope I don’t use it and wouldn’t nor do I understand why you do?

For one I get a 3.8 cubic feet compressed promix for under $30 usd
I unfortunately could not opt for any of their better soil mixes. I would have used MP but the closest place that sells it is over 300 kilometres away and the product is sold for like, $60, I believe? Cost of shipping the product was close to $100 or more.

How long does it take you to get to harvest, on average?

No offence taken, I am overthinking this lol. But here's the rub. Which of the three following fertilizers would be optimal to mix into my soil that would provide my plants with the adequate nutrition to get all the way to harvest: 7 3 3, 3 7 3, or 4 4 8? You can combine one or more of the fertilizers to create a different NPK ratio entirely. High nitrogen isn't very optimal for flower, from what I've gathered.

I did not want to add anything to my plants, the soil mix claimed to have three months of nutrients, and well, that was a lie. I didn't even get three WEEKS of nutrients. I was forced to go and buy something with nitrogen to add to my seed starting mix. Plants almost died.

I'm growing indoors. PROMIX isn't very forthcoming with what they add to their soils. They also lie about how long it feeds your plants for. Seed starting mix claimed to feed for three months. Says it on the bag and their website, I didn't even get three weeks of nutrients before leaves started yellowing.

Each of the bagged granules I have are for different stages of plant growth: veg, flower, and bloom. I can combine two of them (flower and bloom) to make an equal P&K composition.
In that case I'd go with the 7-3-3 or 4-4-8 for veg and the 4-4-8 for flower...and don't forget to add compost or worm castings, because that will help unlock the nutrients in those fertilizers.

Re: how long it is supposed to feed your plants for, that doesn't seem like very useful information. It's dependent on how big of containers you have and what kind of plants you're growing (i.e. if you're growing basil in a 15-gallon pot, it's going to feed for a lot longer than if you're growing tomatoes in a 3-gallon pot).

So mix 1 cup of your gaia 444 with 5g of the promix.Moisten and let sit 3-5 weeks,dont let it dry out.Use this for transplant 1 week before flower.So veg in a 3g pot then just before flip move to a 7-10g pot.

Its basically their version of Ocean Forest or whatever. I wouldn't expect it to have similar characteristics from the seed starting mix. Starting mix is less dense and also should have way less nutrient onboard. I don't think that the Pro-Mix people lie, and people have been using their 'flagship' products for decades happily. But hey, I guess someone on their first grow probably knows best.

I've noticed that you're really spending all your time trying to 'hack' your grow as if there's a magic place that guys who have been growing for decades have missed a whole bunch of tricks. That's a whole lot of wasted energy. I may not have been growing for decades, but probably the best bet is to start by nailing the basics and following the conventional methods for success a few times before you come up with your next level growing system.

Well, maybe they don't lie specifically, but the information on their product certainly isn't all that truthful. How are you going to ignore a label that purports to do something and does something entirely different? It's tantamount to a Honda being advertised as getting you 100,000 miles without needing service, but then one day you're driving along and your engine fails and you haven't even driven 30,000 miles. Are you going to view Honda as being a trustworthy company because people have gotten 100,000 miles without needing service over the decades? My guess is you'll at least want to hold them to account. I didn't want to add ANY nutrients to my soil whatsoever (and I was ridiculed extensively for it) but again, I saw yellow leaves and my hand was forced.

As much as I want to add fertilizer every single time I water (and believe me, I REALLY want to!) I've been told more than enough times that it is a very bad idea. Therefore, I think to save myself a bunch of headaches I should amend my soil prior to transplanting and then never worry about it again. I really don't know what I'm doing, I'm not ashamed to plead ignorance. I just want to do this right once, this time only. Using the fertilizer I have.

Why do people make it so complicated and difficult? :wall:
Not YouTube. Information passed to me on sites like this. I really don;t know what I'm doing, simply watering my plant is proving to be a bit toom uch for me at this stage in my horticultural endeavour.

But anyway, MickFoster I think did a terrific job in relaying to me the information that they did. I thank you for that. I think I'm going to amend my soil with the 3.5 - 5.5 - 5.5 fertilizer before transplanting.

It was a generalization

If you've never grown anything why don't you try taking some advice it appears that you don't want to listen to what people are telling you.
Did that, I've gone between two different extremes: those telling me to not use anything (which still sounds easier) and those who almost DEMAND I use nutrients. Now that I have some experience I'm sort of in the middle. Take a read through this thread I started on 420 if you'd like to see where I was at and where I am now https://www.420magazine.com/community/threads/how-do-i-fertilize.517261/#post-5568720

Obviously I need nutrients, but how much?? I'm trying to grow healthy plants, but I'm also trying to not burn them.

Bob if you shop all over the place you are bound to get conflicting answers
I always found it better to do more reading than asking for opinions
Cause everyone has one just like the planet
Ultimately it is better to do things gradually and not try to use all sorts of mixed opinions or products

So if I run into problems you'll be there to steer my ship right?
