Nutes help

I can't seem to find the answer Im looking for anywhere.

What's nutrient ratios should I be feeding a plant?

I realize during veg nitro should be high, and during veg phosphorus should be higher, and virtually no nitrogen.

But what percentage? They sell such a large variety.
For example, miracle gro has a "bloom" that's 15-30-15
Schultz has one that's 10-54-10
Fox farms Bloom is 2-8-4
And grotek monster Bloom is 0-50-30

So I'm lost.
If I buy the fox farms, do I use 5x the dosage in the water?

If I get grotek, do I use half the dosage?


Help me understand....
What is enough, and what is too much?

Are you growing in soil or what? No nutes for a month after last transplant if in good soil. The ratios with big numbers in them, like over 20, are not something I personally would touch. Big numbers tend to produce nutrient antagonism if not used judiciously, which is just a big fucking mess. Your plants do need nitrogen all the way through harvest, but you do cut back after the first couple weeks of flowering.

Check your nutrient ppm and keep notes on it. Growing is a learning experience and not something you master on the first grow. If you see downward clawing leaf tips, you are over feeding. If your leaves are losing their shine and going pale, you feed more.

What ratio you choose kind of depends on what levels of nutrients you have in your soil to start, so not sure I can give you a formula that works in every case. If you just want to get to some buds, try a 10-10-10 for entire grow, hard to screw up with that! But most try to optimize and that's where many a downfall also begins. LOL

I did leave out a lot of information... Sorry about that.

I'm going in miracle grow soil for my first plant. It's a blue bag of moisture control. Supposed to help avoid over watering....
Not sure what %npk it started as...

I added in a couple tablespoons of miracle grow shake N feed 9-4-12.

I tried to feed some Schultz orchid food in the water, 15-5-5 and the plant showed signs of too much nitrogen. So I just stopped adding the Schultz to the water.

I dunno what to do from this point...
How do I get the slow release nutes out the soil? And what should I be feeding for bloom?


The next plant is gonna be in a pot of promix. It's a 30-10-10 mix says it's good for feeding for 9 months.
I may or may not use the shake N feed with it. It seemed to be good on the first plant though.


If nitrogen is needed all the way through, should I just use the miracle gro Bloom at 15-30-15?

Yeah, you don't feed anything to a plant in a soil that has slow release nutes in it. Water only and not too often. Cheers!

That doesn't make sense... How do you change the npk ratio then when you're going from veg to flower?

I'd reccomend not using Miracle Grow products for future grows my amigo. MG products aren't made for our kind of herb and as a result often lead to problems.

There are veg ferts and there are bloom ferts. Veg ferts have high N typically. Bloom ferts have a low N ratio but higher P & K typically.

You don't, you live with it. To add anything is a mistake.

Some people do just fine with it. They are the masters of not over-watering! Not for me either, I like a more forgiving and organic soil for my style.

Yea that's what I heard. (that miracle gro products are trash for cannabis)

It's literally my first grow and I've been fantasizing about growing a plant since before I even considered smoking it.

I'm in a position in my life where very little factors are telling me not to..
So Im doing it as cheap as possible. Bag seed, budget soil, cfls, sloppy wiring in a cardboard box grow lol

It's a crash course. I germed 5 seeds, planted the 3 with the biggest tap roots, kept the fastest growing plant of the 3.
Turned out to be a female (pretty sure!!)

I did a LOT of research and learned a lot already just off this one plant.

I have a second seedling started and a few more seeds germinating now.

My "plan" is to get a proper grow tent next, and a proper LED grow light.
Then future grows will be done with feminized seeds, in a 50/50 coco coir/perlite medium. (apparently that's really good for growing?)

I'm just trying to get my feet wet.

Yeah, she's nuked with nitrogen so water only, and sparingly. You sound like you are into growing and will do just fine, so do yourself a favor and fix your bad electrical and toss the cardboard box immediately! You don't need the kind of headache you are set up for with that set up. Do this for your own good!

Weed grown on a steady 20-20-20 level does just great. Enjoy the ride!

I've had a few issues. It seemed like over or under watering.
The growth seemed to stop.
The leaves were folding like tacos.
At another point leaves were twisting.
The lower fan leaves' stems turned red, like rusting. (not rust fungus though)
Some leaves started clawing down.
Some started curling up.
Some leaves started getting brown edges,
Others started curling down, along the sides.

A couple leaves got softer and sort of blistered on one half of its fingers.

And one leaf actually burned from being too close to the bulb when I turned the plant and hadn't noticed.

OH and my dog literally ate some of it (you can see some chewed fan leaves in the photos)

Ive had a lot of "issues" that seemed to work themselves out, luckily.



Let's talk about future grows then.

If I go with a coco coir/perlite 50/50 medium

Should I use Schultz: 15-5-5 to veg, and the 10-54-10 for Bloom?

Or is there a better ratio I should look into?
The nutes part is so confusing. The only part I understand is that N is for growth, P is for Bloom and root development, k is for health and antibodies.
But the % are all over the place.
What's too little and what's too much?!

The "bad electrical" is safe (as long as I don't touch the exposed screws in the lamp sockets). I got all the parts and wired it up myself. The unsafe part is all the heat and humidity in a cardboard box lol

But for the moment it was all I could afford. I was going to build a wood box but decided I'm just going to get a mylar tent off Amazon. Couple more weeks till I can afford it.
Stupid budget

Yeah, I'd pull the plug and start over when it is no longer a fire hazard.

Just keep it simple bud. You can't argue Bugeye's results. A straight 20-20-20 nute all the way through is legit. I used Botanicare's Power Plant during veg on my current crop & Advanced Nutes Sensi A&B for Bloom. Not 100% on the NPK on the bottles but I know they're not all equal. Either approach will work. What's important is finding the approach that works for you.

I'm great at following directions. Could have been a chef if I enjoyed the hours.
So whatever works for anyone sould work for me, as long as the ingredients are available and I can replicate the environment.

I'm Canadian, some of the popular American products aren't available here.

I like the simplicity of a 20-20-20, but haven't seen that ratio available. I've not specifically checked a hydroponic store yet. And with my limited understanding so far I thought it was best to alter the amounts when switching from veg to flower. If it doesn't increase yields, or potency, or the increase is negligible, then I'm happier to get one product to use from start to finish.

You could always try a 3 part. It's gonna be obviously more complex than using one nute at say 20-20-20. However, you will be give differing doses of the three parts to cover different needs for all cycles of growth. I guess what I mean is that that your singular 3 part nute purchase will serve you as your veg and bloom food.

You mean buy N, P, and K individually?

I thought about doing that for possibly making my own npk mix down the road.
I read a writeup of making your own organic plant feed but it felt overwhelming as I'm still quite knowledge limited

Thanks for the irrelevant post.
Care to elaborate? Or did you just want to bump your post count..
