    ** if any mods see this, can this please be moved to the sick plants section? sorry, i'm a noob! **
     
    Hey guys,
    I had recently moved a plant indoors and am unsure whether this is causing the yellowing or not.
     
    at first i had overwatered the plant, so i thought the yellowing was due to that, however overnight it has had a rapid change.

    the stems also have a brown line along them (unlike my other plant) as you can see below.

    the acidity of the soil is 6.9-7.0
    the temperature ranges from 25 - 28 deg celcius (not sure about fahrenheit, sorry guys)
     
    i find this totally bizarre and am stumped as all new growth is growing quicker then ever before!
    i've tried to identify these symptoms but can not put my finger on a single proble... i'm assuming there is multiple.
