Amigos ven alguna carencia, exceso o problema ??

The yellow leaf it showing signs of a nitrogen deficiency. I think it’s time to start feeding your plant some nutrients with a properly balanced PH. She should bounce back no problem. I don’t know what your soil is either after looking at your diary. So it’s really hard to say. I don’t like diaries that just use the term “soil”. People call a sphagnum peat moss/coco/ perlite mix soil when in fact it’s not really soil. It looks like it but it’s not. Anyway good luck friend 🤙
