very new first time grow and getting brown leaves at the bottom

hello all i am doing my first ever grow i have 2 baby's only 3 weeks old one seems older due to it being slightly bigger but the smaller one is getting some brown on the bottom leaves i will try and attach some pics the strain is strawberry sour diesel

are you fertalizing them, if so looks like you doing alil too much,,, feed them nothing but water for a couple of days but dont over do it. those are usualy the first leaves to be gone and whats the temp looks like its alil high

Hmm, slightly small for 3 weeks, not bad at all tho a lot of people at 3 weeks are much smaller their first grow (I know mine were).
Kinda hard to tell from the pics, but as plants start getting mature they start losing their leaves from the bottom up. It looks like this is what's probably going on, losing the "non" true leaf sets as it matures.

They look ok to me. Maybe a little overwatering going on.

Yeah, after second glance your plants look great for 3 weeks from seed. Its definitely just using those leaves up and letting them go. I usually tale mine off after they've lost about 75% function.

Good luck, and may you have copious amounts of highly resinous nug in your future

ok thanks all do i cut the brown leaf's off when they are 75% brown and i have only been giving them water

Yeah, I mean the plant could always pull mobile elements from a leaf even if it only has 10% of its healthy tissue left. I generally take mine off when it looks like there isn't much function left, but realistically you could leaf them on (nyuck nyuck) until they fall off themselves.

With those small bottom leaves, you won't notice much of a difference either way.

ok thanks thorganjason
