I am starting to get concerned about two of my Critical Kushs. The have somewhat stunted growth and some pretty extreme upward curling and twisting of new growth. They have been like this for some time and I thought it was maybe genetics but the third Critical Kush looks fantastic. I am kinda confused. I have done some reading around and it looks like it could be related to cal/mag deficiency? It sounds like some cal/mag or Epsom Salts would help correct this issue? Any thoughts? I would love some input they are starting to worry me, they don't look as happy as their sisters! I plan on doing a flush as well in the next day or two. My temps are constantly in the mid seventies to very low eighties. Humidity is a little low around twenty percent. All same medium FFOF with 20% perilite. pH at 6.5 to 7. They have all been receiving same amounts of Grow Big and Big Bloom, and all the others seem fine.
