Dark leaves, clawing

My spidersenses tell me they are overwatered and the nutrients are fine😉

Based on your description doubt it's nitrogen toxicity. Excessive light intensity can cause plants to produce more chlorophyll to protect themselves from light stress, resulting in darker leaves.

I agree with Organoman

Maybe initial stages. dial back a small amount from what a you've been doing. if in soil, may have to amp back up weeks later, depending on how much you are currently supplementing what nutrients came with the soil. Your plants look great, so don't overreact.

Hi bro, Firstly, what type of soil are you using? If the soil is already rich in nutrients, adding extra nutrients can lead to nutrient toxicity. My advice for the next couple of watering times is to use only pH-balanced clear water. Keep a close eye on the plant. If you notice any issues arising, take the necessary steps to address them. Be patient, and everything will go in the right direction. Have a good harvest, bud!
