Hello, I have a question. Do you think this is light burn? I had it too close to a 450w LED for space reasons... Or could it also be over-fertilization? It's only on this leaf, the other plants are doing fine.
If you have some tiny spots on one leaf in your entire grow, you do not have any problems!
The spots are nothing, no deficiency, no burning, no nothing, they are just spots.
No plant will ever have 100% perfect leaves, 100% of the time.
Hey Growmie,
It's really hard to tell because of the color of the light in the background, but I'm more than positive that if it was light burn or overfeeding it affect more than just one leaf it would affect quite a few.
