Metal halide to HPS

[iman]

Hi guys just wondering when you would switch from 400 W metal halide to my 600 W HPS? I was thinking a week after pistols same time for changing to flowering nutes. Sound about right?
Got the scrog net in. I was going to stop tucking them under the net about two weeks after the first pistols were spotted.
Any tips appreciated! Any tips appreciated

I used to switch my HPS after the stretch ended.

I used to switch my HPS after the stretch ended.

Thanks, how do I know when it’s finished? I switched over today 1 week into flowering. Was going to give them one last feed of veg nutes.

Stretch usually lasts the first 3 weeks of flower in my experience anyway some plants are strange

Anywhere from 2-4 weeks in my experience. When the plant stops growing laterally and starts budding.
