I will tell you how to make the best and cheapest fertilizer you can make and it is almost free.......Compost Tea.
Here is a simple Recipe......
Take a Gallon jug and add one cup of good dirt " yard dirt would be great if it is good soil and has not seen any chemical fertilzers or pesticides, if you stick a shovel in and have worms, it is good dirt and you can use it, " then put the cup of dirt in the jug and then add some dried leaves from the yard and some clover " about a handful of each " and then add a quarter cup of Molasses or sugar and a quarter slice of a potato. "
Put all of this together in the jug and add non chlorinated water and an air stone and let it sit for five to seven days.
Strain out and dillute once, so that one gallon, will become two gallons of dilluted compost tea and use it directly on roots when needed and spray the tea through a bottle hand sprayer on the leaves three or four times throughout the grow.
There is you some fertilizer my friend and your girl or girls will thrive!
Nature says; " I have your fertilzer outside, just add water, sugar and air and I will do the rest with my beneficial fungus and bacteria. "
Never have to buy all of this ole fertilizer Bloombastic 2000 stuff again my friend........plants will eat it up.
