Just a touch of nute burn on some of those leaf tips there. I would back off the nutes a tiny bit/ mix the same amount with a bit more water.
Ok! Thank you very much for your fast answer. I will feed her a bit less nutrients tomorrow when it is time for food.
When can I expect her to start forming buds? I'm a bit worried she will grow taller than I'd expected and that might be a problem since she will then be too close to the lights.
Luckily I can move the bulbs 1-2 inches higher if needed, but thats pretty much it. I didn't expect her to grow that big so I didn't do any stem training on her in the grow-phase. Is it too late to start bending the main stem gently towards left/right ?
I suppose I did a little "overkill" on the pot size, hehe..
