Mg deficiency?

Hi guys,


my plants are looking nice and healthy but about 4 days ago i noticed the leaves edges turning lighter green... very strange. I think its magnesium deficiency but i'm not certain.

I've put a teaspoon of epsom salt mixed with 1 Litre of water and have been spraying the plant 3 days in a row now (once a day). I still don't see much of a change.

Is there anything I can do to speed up the recovery? Also, will the change happen in the messed up leaves, or will only new fan leaves look full green as they should, and the ones that suffered from the mg deficiency will stay as they are?


thanks in advance!!

what kind of water are you using because bad tap water could cause issues with calcium "Difficult to distinguish visually. May precipitate with sulfur in solution and cause clouding or residue in tank. Excess calcium may produce deficiencies in magnesium and potassium."


i had a similar issue i flushed the plant and didnt notice signs of recovery until about a week later i lost a few fan leaves as a result, now i use bottled water.

well im using filtered water and mixing that with a tiny bit of tap water just to bring the ph up to 6.2-6.5 but having said that, its almost time to change the filter for the water, so that might be the reason. would you say flushing is the way forward now?
