End of Cycle or something to be afraid
Hi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today). I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes. What do you think?

For a couple weeks there has been some redness in the stalk which I’ve thought nothing of. However, today the edges of some smaller sugar leaves have started to turn purple. Temperature is staying as noted above, should I be concerned?

Potential bud rot?
My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early? I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!
