Cookies in the Parlour

Another steady week and ever improving my environment. This Cream Cookies has now got the full power of one of my Maxibright 315w CHMs right above it thanks to the addition of an LED further up the tent. I'm hoping this gives it a better chance of becoming a star. I know these Cookies dont grow very big and it's more about the taste so I've decided not to top her and just bent the main stem down. That's about all the training she will get before going under the scrog. I've added a few close ups of the fan leaves to show some strange deficiency. I cant put my finger on what it could be so I'm hoping some of you guys can advise. Shes still growing strong and I've added some Calcium and a little Nitrogen to perk her up but still have this strange leaf damage. I'm adamant she will come round though and all being well make a great addition to my tent.
