Bongkhananswered grow question 4 years ago Hey mate ;looks more like a root problem ; when some roots die ;corresponding parts on plant die prematurely without sense. This happened to me when i used a clay like soil. Also hold back on your watering. Let the pot dry out before every feeding. Its like making roots stretch out to find water and inturn grow bigger and healther. Also always check ph. More acidic ph with clay like soil can lead to root rot and thus dying of those leaves.
