I doubt you will "learn something new" from me ;). I learned from old school techniques and growers/breeders (they have books/pdf files around still) like Soma and DJ Short (and many others), I refined their methods to work for my small room and lack of time/money and general laziness I get at times with all the things going on around.
I ended it up with a basic amended soil of: 'Majestic Earth Pro Mix' ($7 for a good sized bag, basically Peat and a little Gypsum, Perlite, Dolomite mix), I add a little more Perlite (~40% sometimes). I then mix those as much as my arms and back can take, and scoop that into my container of choice (3, 5, or 7 gal). I then add ~1 tablespoon per gallon to 1.5 gallons of soil of random organic amendments and as little as ~1 - 2 teaspoon(s) per 3 - 7 gallon container just 1 maybe 2 time(s) per grow. After 4 - 6 weeks, it's usually time to 'top dress' most organics and other amendments.
Only thing to do for the 4 - 6 weeks is add water, usually just tap water with a PUR 3 stage attachment and ~1 tablespoon Molasses per 5 gallons of water to help lower my pH and add some extra sweetener, carbs, etc. for the ladies (we usually don't have much lemon juice around, it goes fast in our house :D). I also try to bubble to water/molasses brew for 12 - 48 hours if I have the time, if I do that, I also add some Mycos (1 tablespoon per 5 gallons, a little overkill I think but it's cheap from a friend locally') and Powdered Aloe (maybe 3/4 teaspoon in 5 gallons).
Organics I like to use are Jobe's, Dr Earth, Down To Earth, Buffa-Loam, 'Earth Juice' ("organic based" according to some websites), and a few others I can't remember right now :(. Also other things I like to use but don't always have around (outdoor garden takes a lot) is: Bat Guano, Kelp, Azomite, Humic Acid, and some more.
Turns into lovely rooms and girls like this:
This is a room (back in 05) with some NL#5, AK47, Northern Berry (F2), Black Widow, NLx, and a Cali O. Grown under a 150w HPS, similar growing/feeding style as I have now (I just use different lights now)

After a little love they look like this (still a little rough, was tough keeping temps/humidity in check in this room... didn't pH anything or even bother to do it back then either)

And the week before I had to take them down (had to take them a few weeks early, dispute with the roommate... that I was growing meds for :confused: girls will do some f'd up things to a guys brain sometimes)

Here is the 'Black' Widow (Mr. Nice called it White Widow when I purchased the pack, but came in a "new" 'Black Widow' labeled package), she is already getting darker leaves like her overly trippy sister I had to water down with NL#5 to get a migraine killing back numbing smoke that hit you just as fast as the BW, no waiting around for NL5 to put you face down in the dirt, it was always about ~20 minutes after you stop smoking.

Almost wished I found this girl when I started breeding NLx, I would have ended up trying to keep a 50/50 blend of the 2, instead of spending 5 years breeding it out. Same migraine killing instant head buzz, but a lot easier on the paranoia and panic attacks. Sorry for the blurry pic, was the last "ok/semi trashed" recovery file from a HD "failure" and was only able to recover the "thumbnail" or something ?

Now how about a 'current' pic of Panama x Med Man grown under my LEDs (had a room light on to get it to focus better, sorry for the yellow messing up my pink LED lit room), was taken a few days ago.
