The light markings between leaves is magnesium and spots are calcium sign. Also showing potassium deficiency. So I am perry sure your ph had drifted upwards too high in that one.

Cal mag. Your ph is likely too high in this one due to coco amount used in substrate. So your experiencing a lock out.

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

Overfeeding?
Is this the first sign of nutrients burn? Some tips of the leaves are turning yellowish and two leaves are starting to make dark dots...maybe too much nitrogen? 🤔The temperatures in my grow box are a little bit low, but I don't think it's the case. The ph is regular.

BT21 Probleme?
Hallo liebe Grower, bei mir ist BT 21. Kann mir jemand sagen warum die Blätter der Blütenstände so „Neongrün“ werden ? Liegt es an Nährstoffen oder zu viel Beleuchtung? Die Lampe ist recht nah dran da keine Luft mehr nach oben ist Wäre super wenn jemand einen Tipp für mich hätte
