rhodes68answered grow question 5 years ago I am no fan of moisture domes beyond the first set of true leaves sprouting.
They are over used and can kill a plant as they need some air movement to keep their respiration working properly.
Cannabis does EXCELLENT at 50% RH at literally all stages of life so I have stopped using them at all but I can control my humidity fairly well not obsessive about it though.
That nuet level should be ok,
This one just looks like a slight PH issue perhaps? Should be fine but its not my grow so your call. Feel free to msg me and we can discuss further if you like.
