sounds confusing but i would just keep it simple and brew some guano teas; a fish aquarium pump, guano or worm casting or even manure, molasses that's all do and i don't even have to PH when i brew tea for 48 hours. coffee might be a good source of nitrogen but the question is does it have beneficial bacteria in it? guanos and worm casting are great for beneficial bateria. in organic growing the population of bateria is most important. get sea bird guano 10-10-2 and use it for vegg and flower if your on a budget. but if you still wanna use thoes methods you mention you can try to make a tea and take note if you see a foam developing your recipee has a good ammount of bateria life to help if it dosent foam up at all and looks like aerated water than it lacks the bacteria thats important for organic grows.
