Ph drops at night this is one reasoning folks with a fuge run the fuge light opposite light schedule to minimize swing. never checked but I do it. With using a doser and it being split up over 24 hours don’t think it would be an issue. You could start after lights to hedge your bets. Your shooting for a 1.5 increase in DKH? It will affect ph but I’ve not had an issue in my rank with similar increase over a cpl days
