I have just noticed my bottom fan leaves are drying up, burning and turning brown. Is this a nutrient problem?

I see your already feeding Cal-Mag... And it being a micro strongly leaning towards this not being a case of magnesium deficiency. Are they lower down on the plant getting no light? If this is the case, the plant does this all it's own and is not a bad sign. Have some hydro growing plants that are already abandoning lower foliage. The new grower growth is where we worry about deficiency.

Bonjour, Je ne suis passur de bien voir mais au dirais que le problemes est le MAGNÉSIUM Sans ce micronutriment immobile, la photosynthèse ne serait pas possible. Ce minéral se trouve au cœur de la molécule chlorophylle et lui permet d’absorber la lumière. La carence en magnésium donnera un aspect écorné aux croissances inférieures. Les feuilles jauniront, sécheront et finiront par prendre une couleur marron. Prévention • Inclure de la chaux dolomitique dans votre substrat de culture • Utiliser un compost riche en fumier • Maintenir un bon équilibre du pH. Solutions • Rincer son substrat avec une eau au pH de 6,0 si ce dernier est inadéquat. • Les sels d’Epsom sont source de magnésium. Ajouter 1–2 cuillères à café de sels d’Epsom à près de 4 l d’eau et appliquer jusqu’à résolution des symptômes. J’espère que cela va t'aider. N'hésite pas avenir me contacter si tu as besoin, plein de courage !! 😊
