Plant issues

Holaaa es difícil diagnosticar a la primera impresión ! Lo más probable hacer un pequeño lavado de roots para luego añadir calcio y magnesio ..la mayoría de los fabricantes entregan la solución lista ! Recuerda regar con agua a 18°C y sin cloro . Puede ser agua hervida

Hi, it's quite hard to diagnose with out a diary to follow or nutrient information, from the looks of the picture I would say calcium deficiency, if you are putting a calmag supplement in your feed then maybe stop, flush and start again on 1/2 strength, if you haven't been supplementing then you can 'try' and light calmag blast, more often then not growers confuse a calmag deficiency by putting 'more' in, what they don't realise is that it can be caused by overfeeding, now your plant looks very 'green' and look to be starting to 'claw' with the nitrogen, which makes me think, flush, start again on 1/2 strength - it's easier to add more than take away!! Hopefully some more experienced growers in this area will correct me if I'm wrong, hope this helps, happy growing 👍
