Need help Identifying The Problem

Title say's it all iv just started noticing only a couple leaves doing this and need to know what it is if anyone can tell?
I use sunshine mix 4 soil-less and fox farm nutes at the recommended doses.

pump up the micro nutes a bit. and the potassion/phosphorus.

it should stop in a week.


might wanna cut back a smidge on the nitrogen too, just a shade or two too dark

Def cut back on the nitorgen, the less the better durning flower.

not using any nitrogen or atleast very very little, the tiger bloom does have trace minerals but maybe there's not enough.

tiger bloom (2-8-4)
big bloom (0.01-0.3-0.7)
beastie bloomz (0-50-30)

bump, need some more opinions.

it could be just the type of strain the girl is

i have it down to a early calcium or manganese deficiency, anyone able to figure out which it is?
