Auto flower grow and LST

Here is where I am at with my grow.I started with 8, I've pulled 2. One is exactly one week behind and the 2nd I'm germinating starting today. And the last auto was not growing as fast but has come back from whatever problem it was suffering from. But here's 4 auto fem on day 16. Also I have started to attempt LST on two if them. Any tips?

an auto doesn't need lst i thought

I asked earlier ways to improve my yield and if i should top them. I got a fee different replies and someone recommended LST. I don't see why you couldn't. I've started two and they seem to be growing as described.I'm sure i have to develop my own technique,but the two I've started on seem to be responding well.
