Royal Critical Automatic

She stopped growing up, but she's still producing new leaves and her flowers keep getting bigger. I think I'm probably gonna get about 10 grams. I'm really worried though, because her lowest leaves are turning yellow and shows burn signs. I thought it was because of the hot weather, but her leaves should have been all bent down (this is what I read on the internet). Since the plant is overall healthy, I guess it might be just normal. Anyway, I found out that it also might be caused by a potassium deficiency, so I'll try and give her some. All been said, I'm still really happy with the results and I love her
