2 oldest leaves look sick and are turning yellow

look like a deficience but im new to growing she sprouted 4-13-13, shes in black gold organic soil, i use 2 26 watt cfl's 6500 k, temps steady at 70-73, also her main stem under the dirst is turning yellowish-brown, dont yet know the ph of the water, but i use tap water that sits for 24 hours plus. introduced her to light nutes twice now, first time at 0.25 ml per cup second time 0.50 ml per cup. noticed small holes in 2 leaves so i used neem oil on her, just today used epsom salt dissolved in water, and feed her. just really wondering what's wrong? cheers

Normal, nothing to worry about. Put some holes in the bottom of that cup.

Bottom two leaves of plants that age die and fall off. They will continue loose a few every now and then.

okay man thanks, just maybe thought definence because the rust colored spots on the leaves. what about the brown stem?

man put some perlite in your soil mix next time

edit: also, just fyi it's spelled deficiency....

thanks, but what's your take on my situation? mostly the stem being brow, and if you think its a deficiency, orjust old leaves dying?

no help anybody? never seen a brown stem? is this normal?

i think what you're seeing is likely because of your soil mix. it can get compacted if there's not enough perlite/something besides just dirt in there. i would definitely not use any nutes this early in a cup that small. you should poke some holes in the bottom so it can have a chance of draining

as far as the stem getting brown at the bottom, as your plant gets bigger the bottom of the stem will become hard and woody. it can even kinda look like it's 'shedding' after a while. i can't really see if that's what's happening here but it's completely normal if it is.

edit: sweet wu-tang shirt btw

but this young of a plant getting a hard woody stem, is this normal or more seen in older plants shes like 20 days old.
