DILLIGAFanswered grow question 5 years ago Hi mate your plants look great but will soon be transitioning into flowering.
Once the intial stretch mode begins your plant WILL need nitrogen and a little P+K aswell as calmag etc etc.
The worst thing you can do during this stage is to starve or stress your girls as it will effect final yield.
So my answer in short is feed them as you were when you last fed them and once the initial stretch is completed or slowed down it will be time to introduce a feeding regime more suited to blooming plants ie Potassium and phosphorus Hope this helps mate Shoot me a message if you need any help 💪
