3-1/2 weeks in the switch and one leaf 2 spots

sorry for not posting details about grow but im have an issue with posting. If post are to long i get a error. I do have a journal up to date so please look to it for details about my grow. Problom is i have just one leaf on one plant with 2 big spots. I really wanna stop what ever im doing now before it spreads. Thank for the help.

I wouldn't do anything

1 leaf with two spots means nothing

and those spots don't indicate anything specific

if I had to guess I say maybe you spilled something on the leaf..fertilizer splashed when you watered idk could be you farted to close to that leaf lol

If it was something i just Didnt want to spread. Over worried i guess. Thanks
