weird prob not really sure possibly genetic

The leaves get like a funky light green around the edges, sometimes on only half the leaf , the tend to horizontally hook and I've never seen our heard of it before. It doesn't effect all the leaves ,usually starts from the beginning but not always, I'm using the botanicare line up, with root excel, in 75/25 coco/perlite also add lime and a light amt of rainbow bloom the strain is dutch passions the ultimate, I guess im wondering if its a genetic prob or other, cause it doesnt seem to effect the results but it s been a prob from day one the degree just varies, also use co2 temps are alll good

nobody has any ideas?

Could the plants be root bound...I ask because when my leaves start to grow sideways it is because they are rootbound...

And I notice my clones leaves do that weird part yellow thing when they are first starting to grow their roots in...so as far as I am concerned all signs lead to some sort of issue with your roots.

i have a constanstly slight fungus gnat prob that i treat with bti (mosquito dunks), could they be the problem
