Trim them off. Looks like they got burnt laying on top of soil. Leaves don't like soil on them. I went back and looked at your week 4 photo.

i would take them out (bugs purpose) but i would also bend the main stem 90 degree to ally the rest to get a lots of light look at my pic i have plenty bend up low stress technique

Cut em off no problem 👍

Ya brother cut out that dead growth only gonna ask for problems especially that colour . They look good especially for doing the move and nuts burn . But anything as dead as those leave should go and defoliation to open her up a bit get better light penetration for the girl..cheers goodluck..

Hey spliff. You definitely want to remove those dead leaves. It can attract pests and become a nightmare. I also see the nutrient burn that you are referring to. I would give them plain ph adjusted water for the next few waterings. It also looks like there may be slight overwatering going on but photos under the led can be deceiving. I keep a small regular light bulb in my room for taking pictures. I also turn my led off when I check on them so I can see any issues more clearly.

So I like to cut those guys off but that’s just me I don’t want the chance of mold to produce in my tent at all.
