Hey there Madkushy!
Welcome!
I subbed up, saw you post over on PW thread. I Want to see the GSC and the Northern Lights. I did a Northern Lights auto some time ago and have a single seed left
I have a clone of GSC but never flowered her, just keep re-cloning for now.
Cheers and those Girls are plenty old enough and look healthy and happy, hack away!
...but seriously they are fine for taking cuts.
I have taken clones younger and that's about the time I take em now.
Seems if you take em down low they don't interfere with anything as it's likely stuff you would remove later anyway....just my 2c, I couldn't tell you which actually is "better" top or bottom but have done both with great success.
Oh If it's "woody" and inflexible might take a bit longer I've come to find.
Hope that might help a bit, looking good and can't wait to see how it turn out!
