Trim or leave it be

• Leaves point upwards.
• Bleaching, which takes the form of white or yellow discoloration, typically on the leaves closest to the light.
• Veins remain green even as the rest of the leaves turn yellow.

• A plant with a nitrogen deficiency also develops yellow patches, but the damage starts from the bottom of the plant and works its way up, while light burn begins at the top, closest to the lights.
• In the case of a nitrogen deficiency, leaves wilt. In the case of a light burn, leaves turn upward and sometimes even become brittle.
• The leaves of a nitrogen deficient plant fall off on their own. This does not happen to plants suffering from a light burn.

I can't tell if you are talking about fluorescent or LED here, but high power LEDs that are too close will damage the plants from the intensity of the light, not the heat created by them.

How to Recognize Light Burn On Your Plants
Because LED lights give off so little heat, you don’t run much risk of causing heat damage by placing your fixture too close to the canopy. What you do risk is light burn. Unfortunately, the light burn is easily mistaken for nitrogen deficiency, and many growers wind up misdiagnosing their grow and addressing the wrong problem.

If your plants have light damage, you’ll see symptoms such as:

• Leaves point upwards.
• Bleaching, which takes the form of white or yellow discoloration, typically on the leaves closest to the light.
• Veins remain green even as the rest of the leaves turn yellow.

A nitrogen deficiency has similar characteristics, but there are a few notable differences.

• A plant with a nitrogen deficiency also develops yellow patches, but the damage starts from the bottom of the plant and works its way up, while light burn begins at the top, closest to the lights.
• In the case of a nitrogen deficiency, leaves wilt. In the case of a light burn, leaves turn upward and sometimes even become brittle.
• The leaves of a nitrogen deficient plant fall off on their own. This does not happen to plants suffering from a light burn.

If it sounds like your plant has a light burn, it’s time to reevaluate the placement of your LED lights.

Of course I pasted it. That's why I included the link to the article that discusses it. It's called providing a source that leads to more information. Are you new to Internet forums?

I would seriously recommend getting a high power light to put over even just one plant (any kind, really...HPS, CMH, or even DIY LED with high effeciency LEDs) and I think you would be very surprised by what you could achieve with one.
