水草情迷

真係唔知點解，之前買袋蝦仔，有條小綠菊向入面，咁我就係咁 2 隊埋落缸，重越生越大，後來執過位，佢就長期合埋，唔開，真唔知點解，我 D 水家陣 PH around 7.4, 水溫 25 - 27 度。

就因為你執過位啦, 有機會傷了根莖位, 要重新再生過.

但佢都合埋左好耐，差唔多成個月喇

I had the same experience before too. The plant was growing beautifully for a few months but suddenly all the leaves closed even when the lights were on. I suspected that was due to a nutrients deficiency problem and thus stunted the plant. I threw the plant away and haven't had the plant again since then.

You might want to read this article and see if your situation is one of those cases.

(A good article for nutrients deficiency)
