Topping a Plant

Hope I’m asking in the right category!! My plants are 5 weeks today, when should I worry about topping ??

Let them grow at least another node before topping. And I would dry off those leaves and avoid spraying them. You can cause lensing burn by leaving droplets on them which can look like nutrient issues.

Awesome, I’m learning from here more and more. Thanks

I would never top before at least 6 nodes plus personally I go more by height then really nodes also depends what space your working with

Welcome ! plant looks healthy Auto or photos

Not sure

This is of critical importance when it comes to training and timing.
Purchased? Given to you? Seed laying around?
If not purchased I would assume it is photo.
