Fans are too heavy on the air hitting plants, going to cause windburn. Going to have a hell of a time with that temp and humidity come flower. Almost tropical in there. With so many plats once they get big you had better have some serious ventilation. Great you are using coco but until your roots fill those pots and your playing with fire with that high humidity and plastic pots with little to no oxygen. Your daytime metric are OK bit you seriously need to get your nighttime down to 50% rh and hold it there, create a negative pressure. Your environment is asking way too much of the plant for the amount of oxygen it can access. Nothing ever good happens in a soil that can't breathe. Oh it can breathe I use coco and perlite! Unless there is a high/low pressure variation nothing will get in or out, top layer of soil quickly compresses and creates a moisture retaining layer which restricts the intake of oxygen especially so in plastic or ceramic pots. Once you harvest plant and all water is removed it consist of 47% Carbon, 43% oxygen, 4% hydrogen, 3% nitrogen, 1% phosphorus, 1% pottasium. These are not precise but to give you a idea of how important oxygen is to a plant at the roots. No one thinks of oxygen as a nutrient but it is. Mother carbon,oxygen and hydrogen Macro npk ca mg and sulfur Micro all the rest less than 1%. Oxygen is king.
