Start simple. General Organics nutrients require NO pHing as long as you follow the feeding schedule(synthetics require a lot of checking with pH or EC/PPM) you can move on to better nutrients and higher quality brands when you know how to get a plant to harvest. Coco or readygro for a medium as they contain no nutrients. so you will not be burning as soon as you start..
I've been growing for about 3 years now and still learn everyday. Hell I had never read up on super cropping and just got some info from a MOD of RIU and BAM! My Blue Dream went from ok to HOLY FUCK SHE LOOKS GOOD..... You will never learn it all.
you can download anything you want off the internet. open your frostwire, click on search, click on books, and type in marijuana. you'll get e-versions of almost everything worth reading. But I will tell you trying to find out a problem you are having by looking in a book almost never helped me. I was never diagnosing correctly. and fucked up a lot of plants.
Get a few essential books, ie. Grow Bible, indoor horticulture.
Watch the DVD's if you want. NICO has the best I've seen. even better and both jeorge's. you can download them too. As long as you are legal or just know your local grow shop owner. most grow themselves and can have some very high quality information and advice for issues or upgrades. Good luck and just get started. as long as you are not trying to run the world with weed as soon as you start up you should get many of the basics down after a grow or two.
