KushGANGanswered grow question 3 years ago Hello greenbell yes you have calmag issue so if you want to correct it soon you need to spray your plant with epsom salts dor quicker effect. Then if you begin to correct your ph you must continue to correct it until the end. In general in soil the ph regulates itself but sometimes you need to correct it after issues. You can use biobizz calmag at 5 ml per liter. Good luck. Bye
