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!2 years ago

End of Cycle or something to be afraidHi 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?Week 6

Cal-mag issue that won't go awayI keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg.
