you already have nutes in your soil, so you dont need an additional nutes the whole grow.
i use a potting soil (soil, woodchips, some rocks and minerals etc.) and i cut it with coco (becuase peat bogs are running low and take forever to form) and perlite.
i take the soil and i premix it with a 1-1-1 compost i purchased. its chicken poop, bone meal, feather meal and potash. this is not only direct food for the plant thats already been broken down (through digestion and through a machine processor) but its also full of biota, or soil life, that will populate the entire soil and turn it fertile!
if you use chemical nutes, it will kill off the soil life, requiring you to supplement food more frequnetly.
i just use the compost. the directions say to add every 8 weeks, so i add every 10 weeks (becuase manufactures make you use more than you need to, so you buy their product quicker)
so i mix the compost prior to sowing seed, and then i just put some on top of the soil and water it in when i switch to flower.
if you use chemical nutes, you should supply them with the fertilizer every 2-3 weeks. be careful though, as this leads to salt and mineral build ups, and the roots will eventually get a lockup.
miracle grow makes good soil (minus the fact that there is a gnat infestation right now) but the company itself is a profit whore POS. they are profit>life so you should never support them. they are monsanto. many companies dump into our mother earth, but when your main product is pesticides, they should be careful, but they arent.
your soil already has a lot of fertilizer in it. if you want, get an organic 1-1-1 fertlizer and use it once or twice more before harvest.
the only problem with big pots is that its hard for people to determine when to water, thats why we use smaller pots. cannabis likes dry soil. a big pot can hold water for 2-4 weeks after the first watereing.
"Polychlorinated biphenyls (PCBs)Until it stopped production in 1977, Monsanto was the source of 99% of the
polychlorinated biphenyls (PCBs) used by U.S. industry.[SUP]
[21][/SUP] PCBs are a
persistent organic pollutant, and cause cancer in animals and likely in humans as well, among other health effects;[SUP]
[73][/SUP] PCBs were initially widely welcomed due to the electrical industry's need for durable, safer (than flammable
mineral oil) cooling and insulating fluid for industrial transformers and capacitors. PCBs were also commonly used as stabilizing additives in the manufacture of flexible PVC coatings for electrical wiring and electronic components to enhance the heat and fire resistance of the PVC.[SUP]
[74][/SUP] They were known to be highly toxic from the beginning, but it was assumed that they would be contained in the products in which they were used. However, as leaks of transformers occurred, and toxicity problems arose near factories, their durability and toxicity became widely recognized as serious problems. PCB production was banned by the U.S. Congress in 1979 and by the Stockholm Convention on Persistent Organic Pollutants in 2001.[SUP]

[edit] United States
In 1926, Monsanto founded and incorporated a
company town named Monsanto, later renamed
Sauget, Illinois. In the late 1960s, the Monsanto plant in Sauget was the nation's largest producer of PCBs, which remain in the water along Dead Creek in Sauget. An EPA official referred to Sauget as "one of the most polluted communities in the region" and "a soup of different chemicals"[SUP]
[77][/SUP]
In 2002, the
Washington Post carried a front page report on Monsanto's legacy of environmental damage in
Anniston, Alabama, related to its legal production of PCBs. Plaintiffs in a lawsuit pending at that time provided documentation showing that the local Monsanto factory knowingly discharged both
mercury and
PCB-laden waste into local creeks for over 40 years.[SUP]
[78][/SUP] In another story published in 2002, the
New York Times reported that during 1969 alone Monsanto had dumped 45 tons of PCBs into Snow Creek, a feeder for Choccolocco Creek which supplies much of the area's drinking water and that the company buried millions of pounds of PCB in open-pit landfills located on hillsides above the plant and surrounding neighborhoods.[SUP]
[79][/SUP] In August 2003,
Solutia and Monsanto agreed to pay plaintiffs $700 million to settle claims by over 20,000 Anniston residents related to PCB contamination.[SUP]
[80][/SUP]
As of 2012, Monsanto is associated with 11 "active"
Superfund sites and 20 "archived" sites in the US, in the EPA's Superfund database.[SUP]
[81][/SUP] Monsanto has been sued, and has settled, multiple times for damaging the health of its employees or residents near its Superfund sites through pollution and poisoning.[SUP]

[edit] United Kingdom
A
UK government report showed that 67 chemicals, including
Agent Orange derivatives, dioxins and
PCBs exclusively made by Monsanto, are leaking from the Brofiscin quarry, near Groesfaen in
Wales, an unlined porous quarry that was not authorized to take chemical wastes. It emerged that the
groundwater had been polluted since the 1970s.[SUP]
[85][/SUP][SUP]
[86][/SUP] The government was criticised for failing to publish information about the scale and exact nature of this contamination. The UK
Environment Agency estimated that it would cost £100m to
clean up the site, called "one of the most contaminated" in the UK.[SUP]

[edit] rBGH (recombinant bovine growth hormone)
Main article:
Bovine somatotropin
Monsanto developed and sold
recombinant bovine somatotropin (also known as
rBST and
rBGH), a synthetic
hormone that increases milk production by 11-16% when injected into cows.[SUP]
[88][/SUP][SUP]
[89][/SUP] In October 2008, Monsanto sold this business, in full, to
Eli Lilly for a price of $300 million plus additional consideration.[SUP]
[90][/SUP]
The use of rBST has been controversial, as described on the
Bovine somatotropin page.
In some markets, milk from cows that are not treated with rBST is sold with labels indicating it is rBST-free; this milk has proved popular with consumers.[SUP]
[91][/SUP] In reaction to this, in early 2008 a pro-rBST advocacy group called "American Farmers for the Advancement and Conservation of Technology" (AFACT),[SUP]
[92][/SUP] made up of dairies and originally affiliated with Monsanto, formed and began lobbying to ban such labels. AFACT stated that "absence" labels can be misleading and imply that milk from cows treated with rBST is inferior.[SUP]
[91][/SUP] The organization was dissolved in 2011 but its website is still accessible.[SUP]

"
If they look good no need to feed them they will tell you when theyre hungry. Get thoes pics up lol 
. Im about 4 weeks from seed, im growing in ffof with 25% added perlite im watering with 6.5 ph tap water and my runoff is coming out at 5.0. The only reason I complaining is because I have some type of deficiency or slight nute burn do to me adding a half of tsp of the General Hydroponics Flora Nova Grow nutes (7-4-10). Im growing in a 3x3 tent with a 400w mh reflector hood my temps stay between 72-75 degrees and humidity between 45%-65%. I don't know what the issue is so any help would be appreciated. By the way the strain is white widow/big bud from attitude. Pic are below. I also heard lime will buffer my ph but idk.
