@Casey420, our gdp! Did the same thing, but mine wasn’t due to any issue except for laziness on the part of my friend where the grow was at. That was my bad for letting that happen years ago. See if this helps you.

Good luck with your grow, happy growing


Thanks for the pictures that will help alot appreciate it
