Brown dots

White Widow Auto RQS 9 weeks old Third grow. My plant started making brown spots one week ago. Today, the problem continues. I feed my plant with Pelargon Terra Bloom, sometimes add Pelargon PK13-14. I don't control ph level, but previous two plants don't have this problem.

Calcium deficiency marks. Very similar to a Potassium deficiency, except the marks doesn’t starts from the edges. Can come from many factors, but mostly due to a high EC level of the Soil. Check the EC of the drain to be sure.

Tengo exactamente el mismo problema en mi semana numero 8 de plantas automáticas, estaba muy seguro de que la deficiencia era de calcium, me he estado matando para saber que sucedió pero como dice @B4RNS, la carencia de calcium puede suceder de exceso de EC, como en mi caso, creo que tengo un bloqueo de nutrientes por exceso de sales en el sustrato. Como otro usuario resolvió mi duda anteriormente mi error fue fertilizar demasiado y nunca dejar que runoff algo de agua de la maceta. En este momento estoy analizando hacer flush y volver a fertilizar con menos cantidad. Si crees que el exceso de fertilizantes puede ser una opción, quizás te pase lo mismo que a mí. Entra a ver mis preguntas recientes, para comparar problemas! un saludo

Just get yourself a pH pen.. consider yourself lucky if you haven’t had issues 2 full grows in. They’re like the price of one seed, it’s a necessity in my mind, but I understand why ppl don’t buy them. Anyhow, no two plants are going to be alike even from the same package/strain.
