It looks like magnesium. But maybe you have the wrong PH, because of this block of elements. Do you have a PH meter? https://www.wietforum.nl/uploads/monthly_2018_10/marijuana-deficiency-chart-jorge-cervantes.thumb.jpg.43e1bbec1925b6fc1e203a4807c496d5.jpg And as colleagues below advised. It is better to rinse the earth / coconut, adjust the PH. And only then water with fertilizers.

Could be any of those.. this is a symptom. There could be many causes that create that symptom. That’s why maintaining a diary and attaching said diary is extremely helpful. What medium you in? What are you feeding? What pH is going in ? What pH is coming out from runoff? What EC is going in ? What EC is coming out? Etc etc etc

PH 6.3 misting soil - RH is 75-80%. - Temp is 77F No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

Grey leaf tips Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?
