When planning your next block of training whether it be for strength, muscle growth or power you will need to carefully balance volume with the increase of strength & recovery times.
Being a natural athlete I know from experience I need extra recovery time during the last few weeks of my training programs. There has to be a trade off between the amount of weight I am lifting & the volume & frequency of the workouts otherwise I will lead into an overtrained state. Signs that you may need more recovery/less volume are; sleeplessness, not wanting to train, loss of hunger & lack of strength.
If you’re feeling somewhat sluggish you may need to back off the amount of sets &/or training days you are completing to help you keep your strength up. Follow a proper nutrition plan & eat as much natural, unprocessed foods where possible, such as what Fitness Meals can provide for you. Aim for 8-9 hour sleep per night & drink plenty of water.
Listen to your body. Train hard but train smart.
