Wondering if I can get some educated opinions here about what this is. I keep getting contradictory advice from people. Not necessarily looking for how to fix it, just want to identify the problem.
I have 48 different strains, and all of them consistently do incredibly well with my food regimen except for 2. I'm doing organics in 1/2 FFOF and 1/2 Sunshine #4 organic. Soil and nutrient ph runs between 6 and 6.5. Very happy with things overall. Note that all of the 46 other types show no sign of this problem at all. For that reason there's no point in asking what I'm feeding them; it's pretty complicated.
Not necessarily looking for 'what to do', but rather just want to know what this is. It happens really fast; within a day or two. Usually happens in veg and then straightens out, but sometimes it will happen in the first week or two of flower. Older fan leaves curl up and turn crumbly.
It is definitely not heat (temps are at 76 degrees F).
P or K deficiency? Why just these two types? The specific types are Afgooey and GodBud.
Thanks for any help on this.
