Help w/ Nutrient Ratio

Ok, I have read all over the place online and have seen 3-1-2, 12-6-6, and a slew of other numbers. Could someone please clear up the air for me on the nutrient ratios. I plan on going with a no soil mix just for less work, probably pro mix. Then a flood and drain system later so Im not spending money on soils. Thank you for your help!

YOu will need different ratio's at different intervals through out your grow... My suggestion is for you to read a botany book or even a book on marijuana cultivation, or hell read both a botany and a marijuana cultivation book. Or try to read The Marijuana Bible, See the trend here? READ...... There is no MAX nutrient ratio, each strain needs different NPK <--- thats the ratio's) at different times. Hell I have a Super Lemon HAze that wants a completely different NPK at 5 weeks in flower than my White Widow.




But what the hell do I know I am just a stoner................

Some food for thought:
