Chow_13answered grow question 2 years ago Not sure about the spots but most likely a nutrient issue caused by your environment being to extreme.
Your second picture is either heat/humidity stress( out of vpd range or just to hot), Light stress( light is to close/bright) or wind stress( to much wind causing the leave to not be able to maintain moisture )
Your leaves also look a shiny green which is usually a sign of to much nitrogen.
