What should I do?

J'utiliserais seulement la lumière de floraison, si elles ont bien terminer leurs végétation j’atteindrais cette lampes.

Hi, if there are both switches on the lamps, I would give full power in bloom :-) Keep it up 🙏🏻👍

When flowering you want as much light as you can get when using blurple leds. So deff have both switches turned on. I would also suggest using the bloom switch for veg as well. Weed is a very light hungry plant and blurple leds don't really out put as much light as other high-quality leds or even HPS lighting does. so I would personally keep all switches on for the whole grow. feel free to dm me if you need any other advice or wanna chat about lighting and stuff! good luck!
