I've been using GH 3 part for 20 years, maybe some Epsom now and then. So what fertilizer do you use? Cheaper than GH?I can get better results using the same ferts I use in the vegetable garden as people using AN. There is nothing special about cannabis. It requires the same things as most other plants. I see all these pictures of crappy looking plants from people using these "Cannabis" specific products to know they are not needed. It's all marketing, stoner science and just blatant lies from many of these companies. But feel free to spend as much on one grow that myself and many others spend on dozens of grows.
I don't buy into all the bullshit, youtube infomercials, and all the other "You need this" crap. I've been growing plants of one kind or another for fifty years.
Go take a browse in the marijuana problems section and look at all the fucked up plants people are growing despite using AN or "X" cannabis specific brand and paying ten to twenty times what those in the know do.
Fancy labels and cool sounding names don't grow good cannabis. A good grower that keeps the environment nice and feeds properly with any nutrient will have great success. Newer growers that buy into the marketing nonsense and follow some ridiculous feeding chart that has you using a dozen bottles of unnecessary shit are not growing anything better than me. All their doing is transferring their money to some shysters bank account.
But feel free to spend $100 a grow on nutrients. I'll spend less than that for a couple of years worth of very good grows. Take a look at the labels on these cannabis specific nutrients. Same shit as products that cost a fraction of the price. It all comes down to the elements and AN nitrogen is no better than the bulk calcium nitrate I buy for dirt cheap just like all those fancy bloom boosters and such are made with the same MKP, potassium sulfate, magnesium sulfate, etc... that I buy in bulk as well for pennies of what it costs to buy AN overpriced nutes. Plant science is real. Cannabis specific marketing is crap.
