Woke up this morning to see the tops of my plants looking like this . It sure what’s going on, I did buy a new HLG 600 r spec on Black Friday and it’s sitting a little close to the plants, I’m thinking it’s from that? Also I defoliated yesterday
That’s kinda what I thought. You have made a classic grower mistake. Don’t feel bad, I did it too.
The new HLG light you got will blow that Mars hydro light out of the water, by quite a lot. Your plants were not accustomed to light that intense. The result is hyper transpiration (aka light burn). The good news is it’s a relatively easy fix. I recommend putting the light on its lowest setting and raising up to 30” from the canopy. That should get you in the proper PAR range and increase the intensity as they grow. The bad news is I’m not sure your plants will recover. Light burn is hard on a plant and sometimes they just stop growing. Good luck
Im gonna limp them across the finish line regardless.. I was pretty sure it was a deficiency compounded with the light stress... I guess now I know better for next time it is only the front plant(biggest one) that looks like this, the other 2 in the back are vibrant green and smell amazing
