AsNoriuanswered grow question 2 years ago That tigery striped leaves are 100 % magnesium issue, but what caused it ?
Could be excess of nitrogen, then it blocks it.
could be just simple lack, thats why calmag is a must suplement for few times during grow.
Could be wrong ph for plant to absorb.
Only you can diagnose, we can only guess....
Epsom salt if its not blocked by nitrogen would be simple solution.
If i remember well, too moist pot for long can play such tricks in soil ...
