Hello. Mayby someone can help me... The leaves on ...

She will be a beast of a plant. I see very little yellowing and at the size of your plant its normal if it’s older leaves located at the bottom. If you are in week 1 of flower you’ll need now consider adding nutrients that include little nitrogen (still very essential in early flower) along with Phosphorous and Potassium also known as Bloom nutrients P&K. At the size of your plant even if your stems are as solid as they are the buds will need support. I’d recommend something like a chicken wire wrapped around your plant or something pf that sort.

@KurakMag Hi mate to be honest they look fine however since they are beginning to flower I would up the feeding schedule a bit with a nutrient mix more suited for blooming ie P&K Also your plants could do with some support maybe bang a few wooden stakes into each pot to act as support for those growing branches Best of luck 💪
