Is this overwatering??

Here is a pic of the lower fan leaves on one of my plants. The leaves in question have a sandpapery feel and are darkening as well. all the new growth on the plants looks great. Can someone give advice?? i dont want to lose plants. also should i cut off affected fan leaves so as to not rob strength from plant??

When i over water my plant usually all the leaves goes down but at your plant there are only two big leaves went down. Is this an autoflower baby which has started to flower...

its new york power diesal seeds from Nirvana seed bank. i dont think its an auto flower. will check with Nirvana

Too much loving. Don't over water and no need to cut leaves.

I wouldn't go pulling off any of the leaves.

It might be over watered. How often do you water?
A small plant doesn't need to be watered as often as a big plant.
Maybe only 1x a week depending on container size.

they are in 3 gallon pots
