What are the best marijuana nutrients? (From Ultra-Cheap to Most Advanced)

How Do You Choose Your Marijuana Nutrients?
If you're growing in soil, you will want to get nutrients made for soil.
If you are growing in any medium besides soil, like coco coir, or a soilless mix, you will want to get nutrients specifically made for hydroponics. Some nutrients are even more specific, like Canna Coco is formulated to work best growing weed in Coco Coir.
Looking for suggestions?
Easy Nutrient System For Growing Marijuana in Soil
One of the easiest and simplest nutrient systems for beginning marijuana growers in soil is Botanicare Pure Blend for soil.
I recommend Botanicare Pure Blend because this system is easy to use, cheap, and can be found at almost any hydro store,
Plus Botanicare Pure Blend for Soil works great for growing marijuana, without needing a lot of extra care, or any additiona supplements.
There are two different bottles that you will need to grow marijuana, "Grow" and "Bloom."
Just use "Grow" during the Vegetative stage and "Bloom" during the Flowering stage. It's super simple.
Make sure you get the version for soil if growing in soil, because Botanicare offers a hydroponic version of the same nutrient line.
Easy Nutrient System For Growing Marijuana with Hydroponics
(coco coir, soilless growing medium, deep water culture, bubbleponics, and basically everything besides soil)
A time-tested, simple nutrient system for growing marijuana hydroponically is the General Hydroponics Trio.
This complete nutrient system can be used in water, coco coir, or any growing medium besides soil and works amazingly well for growing weed, without needing a lot of fuss.
You don't need any other nutrients to grow marijuana hydroponically; this trio alone will give your marijuana plants what they need to flourish through the vegetative and flowering stages.
I love growing with General Hydroponics Trio because I don't have to worry about nutrients and can focus on creating a great growing environment and harvesting my fat buds.
Simply follow the included nutrient schedule (start at half strength and increase as needed) and keep the pH of your water between 5.5-6.5 at the plant roots for best results.
More info on monitoring and adjusting the pH below...
With all nutrient systems, don't start it at full strength or it might burn your plants! Different strains have different preferences, and many are very sensitive to nutrient burn.
Start at half-strength and only raise the amount if you notice that plants are showing signs of not getting enough nutrients, such as growing pale green leaves.
IMPORTANT: Root pH Affects How Well Your Marijuana Aborbs Nutrients!
It's important to maintain the pH of your root environment to prevent nutrient problems.
Some growers get lucky and successfully grow weed without testing the pH of their water, but most people who don't test for pH will start seeing signs of nutrient deficiencies and other nutrient problems.
This is because even if the right amounts of nutrients are present, your weed simply cannot absorb them if the pH isn't in the correct range.
It's actually really easy, quick, and cheap to learn how to check and adjust the pH of your water, and there are "pH test kits" specifically made for this purpose.
After you get the hang of it, checking and adjusting the pH and will take you less than 5 minutes each time you water your plants. And your results (monster yields with huge buds and healthy plants) speak for themselves.
Soil Optimal pH: 6.0 - 7.0
Hydroponics Optimal pH: 5.5 - 6.5
Getting the pH exactly right isn't nearly as important as checking regularly and making sure it stays within these ranges.

***Note: Advanced Nutrients (Grow, Micro, Bloom) offers an expensive nutrient line which is formulated for plants like marijuana, and many growers swear by it. It will definitely work for growing marijuana, no question about it. However, in side-by-side comparisons, cheaper nutrients systems often outperform Advanced Nutrients as far as marijuana yields. I've never tried the Advanced Nutrients line due to the expensive price tag, especially since I've had such great results with these other systems, but I felt the need to mention it because it's so often used to grow marijuana. Here's the Advanced Nutrients calculator to figure out how much you'll need to use: http://www.advancednutrients.com/hydroponics/calc/
With all nutrient systems that you're trying out for the first time, I highly suggest starting at half the recommended nutrient levels when growing weed.
Only increase the concentration of nutrients if you see signs of nutrient deficiencies.
This is because, for whatever reason, most nutrient recommendations are way too strong for growing most strains of marijuana. (Maybe nutrient companies want to sell more by having you use more?)
So if the included nutrient schedule say add a teaspoon to a gallon of water, I'd say you cut that in half and add a ½ teaspoon to a gallon of water. If it says to add 2ml to a liter of water, than you add 1ml to a liter of water.
I've found over and over that you get the best yields by erring on the side of "too little" over "too much" nutrients. I always start a half strength and only move up when I see deficiencies.
For example, I do increase nutrient levels if I notice yellowing leaves towards bottom of plant.
Now yellowing leaves towards the bottom of your plant is okay if you're late in the flowering stage, but this symptom needs to be corrected at any other time earlier in the plant's life (to make sure you have enough leaves that last all the way to the end).
