Leave em until they really drop. You'll be able to pluck em when they're done for. With that age of plant, if you're not feeding yet, now's the time to start.

Edit: looking closer you have some brown spotting on the one major visible one, along with yellow sections with green veins. That might be mag deficiency. Plenty of solutions to that here, just use the search.

I have also noticed that the very tips of some of the leaves are getting a little yellow. Not bad jus the very tips where u can barelly see it. i also had 2 1000watt lights on them at 35inches from the highest leaves was thinking maybe they were hetting light burn

At what level are you feeding? I'm hesitant to say it's mag def just because of its progression -- it's starting at the bottom. I feel the rest of the plant could be a bit denser green as well, but I also notice some leaf curling and tip burn. So it's likely lockout imo.

Full disclosure, I'm not a soil grower, at least not for cannabis. But, symptoms are symptoms all the same.

At a month old, a fan leaf like that dying is indication of more, especially with the brown necrotic spots. Something is either lacking or getting locked out and with the symptoms I really feel it's mag related.

Look up Mulder's chart and evaluate what you're giving the plant against what antagonizes or locks out those provisions. Another soil grower may come along and call me on my shit, but I'm just stating what I see.

What soil are they in?

Light burn will cause curling (you have some, not severe) and bleaching. The lighting isn't the issue.

Once every 3 waterings isn’t enough in my opinion. A month old they are slurping more than you think. Gotta check run off ppm to gauge how much you need to be feeding.

Could u explain a little more i’m not sure what you mean I’m still learning By runoff do you mean how much drains back out after watering?
