Slow buds

Lower the RH at night and increase the PH, they are very dark green so a flush would help too.

They look perfectly fine to me. Actually look great. I think they’ll be just fine. Still have weeks :) keep doing whatever you’re doing.

Some strains can take a little while to pack on some mass. It looks great to be honest. You will notice the bulking start happening soon! Keep up the good work. I hope this helps.
