I seldom get too paranoid about pH, but I suspect you may have a problem in that respect ... don't overwater, don't feed for at least the first 2 weeks, and transplant into a conventional container, with 'mild' soil, when the plant seems strong enough to handle it ... (I dont like Jiffy pots, usually made of peatmoss products, which is too acidic for MJ) ... stop using distilled water, no good, plants need micronutrients, particularly calcium, magnesium, iron, etc... better off with typical tapwater ... good luck :smokin:
