Ba tare da isasshen magnesium ba, chlorophyll a cikin tsoffin ganye ya fara rushewa. Wannan yana haifar da babban alamar ƙarancin magnesium: chlorosis ko yellowing tsakanin veins na shuka, yayin da jijiyoyin suka kasance kore, suna ba da ganyen bayyanar marmara.
Saboda yanayin wayar hannu na magnesium, tsire-tsire za su fara rushe chlorophyll a cikin tsofaffin ganye kuma su jigilar magnesium zuwa ganyayen ƙanana, waɗanda ke da buƙatu mafi girma ga photosynthesis. Don haka, alamar farko ta rashi na magnesium shine chlorosis na tsofaffin ganye, wanda ke ci gaba zuwa ganyayen matasa yayin da rashi ya ci gaba. A ci gaba, rashi na magnesium na iya kama da rashi potassium a waje. A cikin yanayin ƙarancin magnesium, alamun yawanci suna farawa tare da haɓakar chlorotic spots akan nama mai shiga tsakani.
