You don't need to give up yet but can you post more details about your grow?
Temp and Humidity values?
Medium you're using?
Nutrient brand and dose you're feeding?
Light intensity/dimmer setting and how high over the plant?
It looks like heat and light damage to me but not watering enough can cause the same damage regardless of light intensity because the plants itself is drying out.
I also see your humidifier mist in the lower left corner blowing right toward the plant, if the mist gets on the leaves and combined with light and heat can cause the leaves to wrinkle, change color, burn, etc.
How do the buds look themselves? Do the tops looked burnt or anything?
