Think i may have to respectfully disagree with you both. After having more of a think and research. I think its the light, to much, to close, to young. Read below taken from 6 Steps to Cure 99% of Marijuana Growing Problems | Grow Weed Easy

LEDs generate very little heat, but can still light-stress plants, so it's best to keep high powered LEDs (above 90 watts) at least 10 inches away from your plants. When the individual bulbs are bigger than 1W (for example if it has 3W or 5W bulbs), you'll want to keep the lights even further away, up to 2-3 feet for some of the newer, extremely powerful LED grow lights.

It's hard to make exact rules about how far LED grow lights should be from your plants, as each model is so different, so start with trusted lights that are proven for growing marijuana, and just be aware of the possibility of light stress. Start LED grow lights further from your plants than you think you should, and slowly move lights closer each day until you've found the "sweet spot."

To determine if your plant is getting light stressed from LED grow lights, you use the appearance of your plant's leaves to determine if the lights can be moved closer.

If leaves closest to the lights start showing signs of stress (leaves turning brown/crispy or buds being bleached white), move the lights further away.

Use extreme caution when attempting to move your grow lights closer, and avoid moving them more than an inch closer in a day, so you can watch the plant's reaction.
