Would there be any sort of reason I shouldn't add a second less powerful light to the side of my tent? My thought is if my goal is getting more light to the lower growth wouldn't that be a good course of action?
No, he just doesn't what shit advice.
I've seen grow done with 15watt lights.
Yeah, an extra light will only help.
Any extra ppfd will help make better buds
I think you need to get a better main light its very small growth for 5 weeks it will take a year to grow on the lights your using sorry to say but lights and leds have to be decent pull at least 100w per plant sorry to say
