Any help much appreciated

[BigB6]

Problem: Brown dark spots

Medium/grow method: Batmix

Feed: and supplements used: Green sensation, alga bloom, moonshine

water source: Regular water dechlorinated

Strain/age: blueberry cookies, glueberry

light used: Attis 300w

Climate: 24 degrees celsius, 55% humidity

Additional info: I don't know what's going on with these. I've grown them before and haven't had this issue. The development of the buds look fine

Looks Like nutrient lock out - too much nutrients but to be sure we need more information about your PH in the root zone, What feeding schedule are you following - how often are you feeding and how much?

I was thinking that. As they are in the batmix they probably didn't need the nutrients as soon as I gave them. I'm feed every 2 days.
