Can anyone tell me what could be causing these brown spots FF nutes. Pro mix/ espoma soil mix roughly 50/50 with added perlite. End of week 6 of flower.

Phosphorus deficiency and probably magnesium deficiency as well.

I have made sure it has had plenty of extra potassium and phosphorus throughout flower with Alaska bloom fertilizer a couple times throughout the flower period so far
I have recently given it some Epsom salt for the first time. Hopefully that will stop it or slow it down.
 
They nearly always have a huge cal mag need about week 4-5 in bloom. I give it preventative. Otherwise none unless I see a deficiency developing. They look good overall. Good luck and keep us posted.

thanks the are super frosty and buds are getting bigger super stoked for my first grow. Just bag seed but the smell of blueberries when you touch them I’m hoping that just keeps getting better. I’ll keep that calmag thing in mind for next run thanks
