Tropicanna RDWC

Hello to you all. This week was a great week of recovery for me...can't say that about my plants xP As I wanted to perform some overdue LST, a main stem of Tropicanna Poison XL broke under my fingers...all of the plants are stiff AF and break like glass, no way for LST i broke many more twigs while trying it in all the plants and strains. I have no idea what caused it, could be an agglomeration of things: the cold temperatures, high RH, lack of minerals. No nutrients were added to the reservoir this week the solution is stable. The SE 7000 is set on 55-60% of power. That's it, I hope to see y'all next week growmies.
