help me plz

me and my buddy are haveing some troubles with are plant. The bottem of are leaves are like dieing down and and turning yellow at the tip and curling upword and its starting at the upper leaves. We dont know what to do for it we think its lacking Magnesium. Thats what is saying in our Cannabis Cultivator book and we dont know what to add to the soil. It says to use a stumic settling salt. Hers the quistion, what could we use to treat it? and thank you for helping us if you read this.

can u get some pics up, what kind of setup are you using ie, lights, nutes, soil ect

pc planter set up, with regular dirt and spraying miracle grow all purpose plant food every once and a while.

well miracle grow really isnt for cannabis, that could be the prob. I would stop using that and see how it goes. but more info is needed, growing is a science down to every drop of water and watt of light.

yeah we stop yesterday and put her under natural sunlight kinda perked it up i think it might of been nute burn. thanx though

i went to the local hydro store and grabed some indo bat guano and worm castings anyone know any good tea mixs for our lady
