Leaf browning, yellowing curl one day change.

Thank you. It has been raining a lot over the past 2 weeks, I try and move it in under cover before the rains come but not always successful. I will try and let it dry out and keep it out of the rain. I will pluck off all the dead leaves and hopefully it improves. Any recommendations for a fungicide, I live in Thailand so preferably something that is widely available and of course safe.

Wish you had a diary for this grow... the reasons could be many but without a diary, it's very difficult to assess... I DO think you're dealing with a calcium deficiency but there may also be some fungus issues or root rot issues or, or, or... Definitely start a diary on this and go back as far as you can with the weeks giving as much information as you can possibly remember and then come ask your question again... Good luck!

Hmmm looks like it’s feeding off its leaves 🤔 id remove them effected leaves a try a booster and see if it gives it a pick me up… Dont over water and monitor it, Beat of luck 🌱
