it's a long story. but when i started it was just me and the plant. not a lot of internet forums around. we learned by listening to the plant. there weren't a lot of books to "tell us what to do", so we let the plant tell us. i listened.
And then there are all the different requirements for different strains,
which makes it impossible to write about.
I have 6 different strains budding now and 1 of them can't get enough nutes, another doesn't like too many nutes, and the rest are somewhere in between.
Life would be so much easier if there was a formula for all plants, but, alas, this will never happen.
This is where the listening to your plants comes in, and can take years of experience just to get close to giving them what they need.
And for outdoors there is the weather to contend with.
They say a vintage year for wine is 100 hundred days of uninterupted sunshine up until harvest time.
Probably the same is true with mary, so some years you will harvest much more than others, and the quality may vary from year to year.
Just my thoughts on the subject.
ps: whats with the tent FDD, are you guarding your babies at night?
