600w HPS 2 plant LST.. Bit of advice for second grow

I've got 2 plants growing in canna professional soil and 5 gal pots (big bang) growing in a 4x4 tent with 600w HPS..using canna veg, canna flowers, pk 13/14 and bio boost.
Im LSTing and there doing well (3 weeks from seed at the min)
This is my second grow, my first grow was unknown strain with 6 plants in 12 litre pots, had some probs on my first grow, nute burn, and lockout I think, was not PH testing. Anyway I got just iver 10oz dry and I was happy with that tbh.
anyways so im curious would I be able to pull over 10oz with just 2 plants this time (im a little more experienced) plus I will be getting the PH bang on all the way threw, and im using LST this time? I'm wanting to fill the tent with 2 LSTed monsters to get a good yield so how long do you think I should veg?
Thanks for any replies and sharing the knowledge

I love LST. I learned from past mistakes and corrected them on my current grow.

I had always read that article with the diagram that shows the stem wrapped all the way around the perimeter of the pot. I had about two/fifths of the way around and had enough stems in action, and figured letting them go more would get hard to manage, so I flowered then. Could have gone longer/bigger, but I have four plants in a tent I designed for three at most, so it's crowded enough.

With only two plants and larger pots than mine (similar sized tents) you could go for a long time, but "stem management" gets old after a while. So, I would say you should veg for as long as you want to.

Thanks, yeah I think ill always LST from now on, I think ill veg for 8 week, keep topping and hard stress training too.(longer if I have to) Im not in no rush to put it into flower I still got plenty of smoke from my first grow long as I get 2 monster plants to flower im happy
