abbreviations?

I was wondering if anyone had a word key or something? Ive been reading through the forum and i cant realy get an understanding of whats being talked about if i knew some of the meanings of like ppm, and lst , i do know these two but there just examples. Anyone help me out?:jointsmile:

We can add this all seperately but here are a few:

LST- Low stress training (bending for space and more light).

FIM- F**K I missed (cutting like topping but different <<Research>>)

SOG- Sea of green (green every 2 weeks etc...)

SCROG- ugghh... Mesh placed on top of grow to allow more light to reach the buds)

PPM- parts per million (= way to judge strength of nute solution in hydro and quality of water)
EC- electrical conductivity, related to PPM
