i do remember the conversation mate but i cant visualise the picture. tbh if youve flushed and added the epsom salts there not much else i can suggest. give them a couple od days and re-flush, no more epsms though, then just give them plain water for a week. this should clear out any build up in the soil. this is going to slow your growth pattern down a bit but better to be safe than sorry. remove any badly damaged leaves and take a pair of scissors and cut the ends off leaves that are just partly damaged. after that just observe the plant and see if any further changes are happening. the leaves may start lightning in this week if there is no nutes in the soil, maybe add sum vegging nutes at this point along with a quarter strength flowering nutes
