Hmm I didn't think seaweed could do that because it's meant to only have very low amounts of NPK's, and that frequency of epsom salts is fine, how many tsp/L? 1 tsp/3L? I remember reading something about houseplants getting burnt leaf tips just from overwatering and nothing else so maybe that's why the tips are burnt because your soil could be too heavy and keeping the roots wet too long? I can't tell because I don't know how often you water or how fast they drink it..
