Vietnamese Landrace Sativa monster

All going well, seems to be progressing nicely, buds all starting to gain some substance, has a lovely sweet smell also, almost mellow citrus like, very pleasing. Still having clawing issues with the topmost few fan leaves, strange that it's reserved to just the top couple. Not sure what's going on, but that aside the plant seems in good vigour. There really a few sad looking leaves on the pictures, I gave it a trim down after the pics, wanted to post an honest representation of my grow, not a beatification of it, so decided to take pics then trim. She's getting huge now, thankfully still fitting beneath my lights.
