Hey bud, saw the photos - if this issue is isolated only to one or two leaves I’d just keep an eye on it for any more spreading to other parts of the plant. It could be early signs of some nute lockout or you might have your grow light a little too low (18-24” for most leds to prevent light burning). I wouldn’t worry too much as the rest of the plant looks really healthy. Might be able to tell you more if you have been testing your ph levels. Not seeing a stat on that. Lookn nice bro! 👍
