Yeah mate, Top Tip Number 1.
Don't tip the third node lol.
Youve done it there before u take it though.
Only time I can top autos is day14-17 if the 4th node is there to chop off.
Every time I've done it without exactly that, I've stunted. Sometimes pretty badly. Now I just stick to that rule or let them grow as they want to.
I've always been a great believer in topping autos cos my first year I just got lucky and always done it at that time.
I realised pretty quickly on year 2 that it was all in the timing
