That is completely normal. Circle of life, blah blah blah. Unless you are seeing an excessive number of leaves. The plant is basically sucking the life out of those lower leaves and branches to build the new growth.

Sometimes this can be a sign that the plant doesn't have the necessary nutrients to build up. This can be caused by your PH being off the charts or using crummy soil.

Can you give more details about your setup? What type of soil you are using, what kind of lighting, etc?

Pics would be most helpful for a diagnosis.

well im using cheap potting soil..but its too late for that now..and i used some p[lant food..but the numbers are wrong 11-3-7 or somethin...but i thought it would help..and light is from sun..any more advice

If they new leaves are healthy and the plant is continuing to grow, I wouldn't be concerned. You should start ferts about 1 month after they've sprouted, any decent soil should have enough nutes to keep it until then. If you fertilized your soil already and you see some of the newer leaves starting to turn yellow/brown around the edges, that could be nute burns and you would want to flush your plant to drain the ferts.

I bet you don't dechlorinize your water

shiiit...so i how do i flush my plant..it may getting burnt from the fert...

Do you ph test? If not begin asap.
