Huh, I used to be the one in here answering folks questions but this one has me stumped a bit. All pics are of the same plant.

The first two are from last Wednesday. Zoom in to see tons of small bumps and both sides of the leaf. No visible bugs or eggs. The final pic is from today and includes some edge curl. Maybe copper?signal-2017-05-31-224801-1.jpg signal-2017-05-31-224756-1.jpg signal-2017-06-05-132711.jpg

Any help or insight is appreciated.

I hate to say it cuz ive been saying it so much

but im going with a combination of magnesium def/lockout
and a little heavy on the N

and id say its time to re-pot up

the reasons I say magnesium def;
for me leaf curl is a sign of two things, either heat stress or magnesium def

but you also have the classic magnesium def twist showing in the new growth along with the discoloring in the lower

in my opinion;
consider you might be slightly over feeding or you've got a very hot soil if its organic

they look great, don't get me wrong
but there very dark green
if your fertilizer is high in K and your feeding heavy it could lock out magnesium
or if your fertilizer is light on magnesium you could be def

I would water with only 1/4 tsp Epsom salt only ...no other fertilizers for the next couple waterings
and back off on the fertilizer a bit

These have not been fed at all yet. They were just logged in Happy Frog. I'll let him know go try a little calmag or Epsom. All the Ca+/Mg+ symptoms I have ever seen have been kinks or twists in leaves and not dots or edge curl. Thanks!

if there in happy frog and haven't received any fertilizer then that narrows it down

the fox farm soils seem to be light on calcium and magnesium and those are the first two things to show as lacking

calmag is primarily for calcium its not really got much magnesium in it, some but not much
use calmag for calcium

use Epsom salt for magnesium

usually 2 to 4 mls calmag and 1/4 tsp Epsom salt every week or two is a good combo

if it was a micro nutrient like cooper or iron or zinc
it would show in the top new growth

npk shows first in the bottom growth

calcium usually low with red/rust colored freckles or spot
magnesium varies, could be top, bottom or both, usually itll discolor at the bottom and twist at the top and the fan leaves conoe or taco
the taco can also be caused by heat stress

youll need to feel out how much to add as you go, but those are safe/low amounts provided you don't add it every day lol
