Yellow & brown spots appearing on leaves

[heyhighhello]

Hey guys,

My plant is about 4 weeks since sprouting, currently in veg state. It's been doing well the first few weeks but I'm starting to see a lot of yellow/brown spots appearing on the older leaves from the bottom. I can't figure out what's wrong, is it lack of nutrients? And I only water it when the soil from below the surface has dried out a bit so I make sure not to overwater it.

Can someone help me figure out what's wrong before it dies?

here's a photo

It gets around 5 hours of indirect sunlight and then around 6 hours of direct sunlight, and then I keep it in my room with the lights turned on.

Should I start feeding with nutrients?

I make sure not to hit the leaves whenever I feed it

Check for mites...

From what I looked up about mites, I don't think mine seems to be having a mite problem. The oldest leaves at the bottom seem to be curling in and look like they're drying out. Could it be under watered?

is he plant getting too big for the pot ? show us a picture of pot and plant , the roots will also not like the light going through your starter pot if the roots are hitting the edges

Here's a photo of plant and its pot. Not sure if its getting too big for the pot, but I don't see any root tips at the bottom

You can see the bottom leaves curling and yellowing

Could be under-watered, but it doesn't look like it to me (at all).
When MJ is under-watered, you don't have to wonder. You will know. It is WAY more common for them to be over-watered which can mimic an under-watered condition.

Your pot has drain holes, right? It isn't very full of soil.

it looks like shes in about 2-3 inch of soil , should have filled that pot an used a dark permanent marker or covered to darken it
