Hi Dimax. That's a nice and promising bush you've grown👍
As for your question about the leaves. She does look a bit stressed, but not critically. In fact, scores and hundreds of plants have been seen to grow, bloom and yield successfully with foliage damaged like that or slightly worse. Unless this symptom increases there isn't really a reason to worry.
Have you considered the possibility that nutrients dosage may've been miscalculated?
