I agree with what has been said it does look like a slight deficiency issue but this can easily be rectified ๐
Your ph is way to high for soil/coco. Ideally you want your ph around 5.8-6.3 ๐
Going of the ppm pen that would make your ec around 0.4ec which is low and I would indeed this up to 1200ppm โ๏ธ or 0.6ec ๐
A bit of calcium and magnesium will do the trick my friend ๐
Good luck with this grow. Thank you for choosing our genetics for this adventure and we will be watching with interest from Humboldt county โ๏ธ
Kind regards
