I'm from MI as well but I kept my card for many reasons, patients still have more rights than rec users, this may not matter to you but we only pay 6% tax at the dispensary vs the rec tax rate. Also, I enjoy the little bit of protection of my job as well at least as a med patient if I get fired...
molasses does not feed plants it feeds soil if you are going to mess with molasses then you want to run the grow with living soil and yes you need fertilizer something ORMI listed top-dressed get you some nice organic tomato food from Lowes use that and use your molasses get some compost in that...
