Hi friends ! Can you help me to diagnose if this is potassium deficiency?? Older leaves look yellowish and with burnt edges
I’m really new at this ! It’s my first plant and I could really use some help.

Slight underwatering? I wouldn't be overly concerned those are old leaves and it's not abnormal.

Imo looks more like a watering issue.

What's the media and watering practices?
Including feeding info.

Thank you Aqua Man !
Maybe that’s the issue because I was very afraid of overwatering it… now what I do is I wait for the soil to dry out (2-3 days) and I give it a good soak.

As they grow the demand will increase so its an ever changing process.

And the stems color is completely normal.

It also looks like it could need a bigger pot. Soil looks kinda low in picture and pot looks kinda small. A little hard to tell though.
