No pins after 15 days and maybe contam?

now 15 days after cutting the top off and still no pins( strain: PE )ive misted alot at first but have been toning it down to only misting if walls are dry and fanning air in twice a day, but ive also noticed the top of myc is blue and also getting these black/gray spots and was hoping to get some clarification as to whats going as because im a complete noob first time ever doing this so any help woukd be greatly appreciated thank you 8)

Blue spots with some black/gray tint is bruising, it's not a contamination. Most likely it's appeared due to heavy misting and/or fanning. For the future try to avoid misting the mycelium directly, water drops and water pools on mycelium, and hard fanning.

Check out more info and examples here: Mycelium bruising.

Is it all-in-one growkit/growbag? Or did you make this block yourself? I’d give it another week, since there are still some bald, uncolonized areas on the sides. I’d also skip misting for the first flush for this tek. We’ll see what to do next…
