whats missing

can anyone tell me why the bottom leaves are drying up? ive spraid neem oil for mites but she seems to be getting dry i hope it doesnt affect budding can you help me out sorry for pic quality

what are you feeding it

I would cut off crusties and not trip as long as new top new growth looks happy. Do you have a dog that pees on it?

The snoopy tree !i

yea alittle chihuahua peez on it so it has a smell on the bottom leaves i use no fertz bug i have a seaweed extract i feed once a month i will cut all yellow leaves thanks guys

If possible put small fence around bottom area to stop dog pee

it could use more nitrogen

ammonium sulfate will do the trick? i got a screen from last years grow.
