Browning, dryed up leaves

Slowly and surley s.h.i.n.m's* (someone who is not me) plant has been turning brownish and drying up. The plants bottom leaves are developing browning blotches on the leaves and slowly killing those single leaves.

he cut off both the bottom fan leaves because they were perdy much dead, now it has started to rise up to the next set of leaves...wtf

i might wanna mention that its a pretty stretched out plant cuz normal house lights were used for the first week or so

wut should s.h.i.n.m do?

First off, have you been ph-ing your feeds?

Secondly, yellowing leaves that start from the bottom of the plant and work their way up is caused by undernuting. Usually the basic NPK.

Check the colour of the leaf stems, and main branches and look for any purpling or redding. On the main stem these may appear as streaks...

Undernuting can be caused by two things... either you're not giving your plants enough nutes... or you're locking the nutrients out, making them unavailable to the plant.
