I’m having a problem with some large fan leaves discoloring, curling at tips, drying out, and dying on this 7 week old Cali Orange clone. Other leaves look as healthy as can be. This is my 5th grow but I’ve grown perpetually for the past 13 months and have not experienced this particular problem. I’ve looked under magnification and observed no insects. I learned the hard way about spider mites so if it’s a bug I don’t see it.

* use FFOF in 7 gal fabric pots
* only feed once/week with FF BigGrow 2tsp/gal
* add 5cc CalMag Plus once/week
* 1/4 tsp Myco+ once/week
* 1/2 tsp Snowstorm Ultra once/week
* plain r/o water other days.

I water every morning approximately 1.5 gal of water for all 5 clones. They are in closet waiting to go in tent (chopping tent grow tomorrow). This leaf problem has seemed to happen overnight. This is a new problem to me that I haven’t seen in my other four grows and one year experience.
