Genetic and or deficency problem?

Hey guys,

Strain is Mekong high from dutch passion
Any idea what would cause leaf to look like that ?
I think It may be more than one problem but it's the only strain acting up in the greenhouse. They been that way since they were 4 weeks old and are 10 weeks now
I have 2 of them (from seeds) and both are doing the same thing all the other plants are stong and healthy.

Plants are in 15gal smart pot living soil with dry amendments (alfalfa meal, rock dust, kelp) and are watered with earthworm tea once a week. Tea PH is 6.5


Leaf have been like that since the plants were 4 weeks old. I think it maybe be bad genetics.

Then came the spots on the older leaf. Does it look like a calcium deficiency to you ?

Perhaps increase your overall NPK macro's.. like potassium; a stronger tea for those girls/ or higher K in the tea.
?
just idea for you, I'm not sure.

(Also, perhaps something you are spraying them, they don't like/ are sensitive more than others and residual is causing some kind of burn, or in combination from light?)

You check for bugs?

No unwanted bugs so far.
My teas are very mild 300-400 ppm
I will give these girls stronger tea and will add egg shell dust and empsom salt

looks like a calmag to me

treat with a foliar spray 3ml/gal and see if it improves
