Looks like heat stress.
What size light and how close?
What are your temps?

Last pic looks like overwatering the other
ones could be heat or maybe ph issues
What kind of dirt is that? How close is
the light, type and wattage?

some strains do not like 83. Sometimes even among siblings there are some that are more resistant to heat stress. See if you can keep the temps 80 or lower and it may help.

how do you get magnesium deficiency from that? There's no discoloring at all. I would say heat stress, but 83 isn't all that hot. I don't even check my temps anymore. put your hand between the light and plant, palm side down. If it's too hot for you, it's too hot for them.
