Hello maximus!
If possible, may we obtain more information about this grow of yours? What kind of soil are you using? How often are you watering/feeding? What kind of nutrients are you giving her?
Just from the pictures, it looks like it could be a few things.
1. One possibility is that from the look of the tip of your leaves yellowing, it could be a nutrient burn (too much nutrients). I would refrain from feeding her, and just give her some water when she's looking thirsty. If it starts to get worse, I would recommend performing a flush to drain out the excess nutrients in the soil.
2. Another possibility could be that you might be giving it too much water, from the browning of the tip of the leaves in pictures 2,3,5,6,and 7. This can be caused by giving her too much water at once and completely turning the soil into a pool of water; watering her until there is runoff, but you do not drain out the runoff (usually runoff contains salt. Salt = Bad); or you may be just watering her too often. Make sure the soil is completely dry (very light colored soil), then water her or feed her, whichever is appropriate.
I have read that it is always better to under-water your plants (leaves starts drooping) than to over-water them.
3. The final possibility (highly unlikely, imo), but in pictures 3 and 6 with the tip of the leaves pointing up, if you have any lights that are nearby the sides of the pot, it could be possible that it could be too close to the plant (light burn).
I could be wrong, but just from your pictures, these are the possibilities of what it looks like to me.

wow.... apparently I took too long to post my information.
