Need help damaged cotyledons and stem

My Durban poison auto is growing well now but my cotyledons are dying and there is a brown spot on the stem but the plant is growing well please help me I'm really worried

Please don't overreact. Cotyledons have no major impact on the plant. Their function is to feed the plant with stored energy until the firat set of real leaves come. It's fine.

But what's wrong with the stem that's what worries me

Do you freak if you get a pimple or zit? A brown spot means nothing. The leaves look good. Thats what matters most.

Nothing is wrong with your plant at all bud....the plant is just putting energy and nutrients into areas that are more important to the plant..nothing is wrong, it can be really tough not to overstress over things such as this, but believe me...overworrying can cause you to make rash decisions that end up harming your plants.

Really wanted to hear this , it's my first grow that's why i was freaking out cause I don't know much about cannabis grow anyway guys thanks for clearing my doubt.
