Yeah, can’t tell anything with that light. I’ll be the first to say it. Blurple light is not preferred. Probably not your issue, but I’d be looking at upgrading when you can. Something with Samsung diodes. I’m partial to HLG because I’ve had good results.


Never grew that strain but the name fits the description of what I’m seeing

I am using a KingLED 2,500W with both the Veg & Bloom lights on.

Try taking a photo with flash turned on and the grow light turned off. Natural lighting helps see just how much yellow you are dealing with and diagnose what maybe causing it.
