Leaf spots

[noobman76]

hi all, I have 3 green poisons and 1 big bud northern lights in my tent . green poison have around a week to go and leaves are starting to lighten up and yellow a little and I read that this is normal, but my BB/nl has around another 2 weeks to go and is fattening up nicely but some leaves have started to get blackish spots on em, any ideas?

overwatering most likely...pic of whole plant would help

looks like they are coming to an end of their life....Id back off the water a bit and give it a feeding....if it doesnt respond I wouldnt worry to much.
