You can rest assured that there is nothing wrong with your plant! Newly emerged leaves (center ones) are often a lighter color than older leaves but as they mature, the color will darken to match their older cousins.

And the brown line(s) are just slight mechanical damage, probably caused by transport.

This is really a very easy care houseplant. Keep the soil just moist to the touch - not too wet or too dry. Keep out of drafts and provide bright indirect light. Fertilize now and again. Doesn't ask for much more :-)

Thanks a lot garden girl. And when older leaf turn complete yellow, it’s fine for me to cut it off right? I just did this morning... I think I’m a very anxious plant parent.

plz.. it s plant.. not a child.. treat it like a plant ... and you will be further ahead.. in the long run .. it doesnt need constant feeding.. clothing.. nor a college education ... its a plant ...

all the brown lines.. it looks like the leaves got folded ... we call it mechanical damage.. as gal notes ... as compared to disease or bugs.. or other things .. ignore it ... sooner or later.. and the plant starts putting out new leaves.. you can snip those out ... keep in mind.. even a damaged leaf can produce energy from light .. there is no hurry to take it off.. until it all yellows or browns ...

and no plant holds it leaves forever .. and they usually shed leaves when light levels fall .. otherwise known as winter.. so expect such.. and dont freak out when it happens ...

leaves are energy making machines.. and are replaced ... just dont go cutting a lot off at one time ... but otherwise. snipping out one or 2 is nbd ...

just learn how to properly water a houseplant ... in your house .. and otherwise.. dont fix or worry about much of anything .. its a plant ...

if you stop watering.. and make a note of the date ... you will find out when the plant needs to be watered .. because it will wilt ... then .. in the future ... a couple days before the period discovered .. water it ....

not many plants need constant daily watering .. and such can lead to problems.. like rotting the roots off .. and then its a dead plant ..

you can also tell how much water is in the pot.. by how much the pot weighs.. water it.. and hoik it.. and then dont water. .until it loses/uses enough water that the pot feels lighter ...

and then there is the usual direction.. insert finger.. and find out about moisture at depth... we really dont care about the surface of the media .. that can 'look' dry all the time.. but the plant usually doesnt have roots there ...

bottom line.. its a plant .. enjoy it.. relax .. its not rocket science .. and dont kill it with too much love ..

ps: does your pot have a drain hole?? ... if not.. let teach you how to repot it ...

ken thank you so much!
