keep in mind this plant is for lack of a better word a weed. it needs the same thing as every other plant on this planet which is N-P-K.
No offence but I disagree with this. Ill explain
Nutrients are classified in 2 ways Mobile and Immobile.
Moble nuts move freely around the plant as they are needed. If you have a nitrogen difficency, the lower leafs will release their nitrogen and move it to the upper leafs (clsoer to the light). The bottom leafs turn Yellow.
Immoble nuts never move and stay where they are.
Macronutrients are NPK
Nitrogen Potassium and phosphorous
Micro nuts are everything else
Nitrogen moble
Phosphorus moble
Potassium moble
Magnesium moble
Zink moble
calicum Immoble
boron Immoble
Chlorine Immoble
Cobalt Immoble
Copper Immoble
Iron Immoble
Manganese Immoble

There are diffrences of opinion of what amounts of what are better or worse for plants hense the diffrent brands. I am friends with a couple owners of some of the companies mentioned here. The irony is some times people sell the same products with a diffrent brand name and people think one is better than the other when they are exactly the same. What is better and worse depends on the enviornment you grow in. Ohh and don't buy anything for hydroponic use at walmart and NEVER use miracle grow (burn).
