Looks like you may have wasted some water/nutrient solution on the leaf and it was possibly magnified by the lights.

Do u spray the foliage perhaps?

I don’t believe so, I am not doing any top watering and it is showing up on new growth as well, though still in small amounts.

Lets see the new spots. Those dont really scream deficiency imo.

Nor bug damage…

One thing I did notice is you are a hydro grower. And the sweet spot pH wise is 5.8-6.2. You may want to drop it a few points if possible

Thanks! I will try lowering the ph a bit to get in that range. Here is a photo of the new growth. I could see the spots as the leaf was unraveling and they were dark but the leaf has now unraveled and looks very similar to the spots in previous photos.

Yup thats a spread alright. Blotches are too big to be calcium. And too few.

I wouldnt think P nor K as well. Getting them in range should stop the spread for ya

Great, thank you! I will get on that.
