White widow/ Royal Gorilla

Missed out a few week due to lots going on in my life but was looking after the little ladies still like my own child. They were growing nicely and at week 9 I have started the flowering phase with 36hours of darkness than with adding tiger bloom to the feeding. Second week they are in to the flowering phase and growing nicely and the flowers are starting to appear on a lot of places. I have some issues with leaves turning yellow than falling off which im going to raise with the professional here and hopefully will come to a solution. I do have a feeling they are lacking one of the nutrients but we shall see. Will be updating on that next week. Pictures were taken when light was off so they were sleeping and that is the reason the leaves are folded.
