I never liked that ocean forest or soils similar to that . Could be a hot batch with all the guanos and what not that they put in it. Probably better off with Pro mix or something similar and just add your own nutrients .

u lacking mag feed with Epsom salt 1g per gallon add it to the water FIRST then what ever els then ph then feed

ps id start out with less then 1g for sure let your plant get a feel for it before giving it a full dose and burning the holy hell out of her
