🇩🇪Purple cookie kush 1st grow

Hello again, Flower Day 34 today. Hope you guys are doing good. The PCK has grown well over the last Week and is packing on some mass on those buds. The trichome production is really great and she is delevoping a certain smell and stickyness when you touch the sugar leaves/buds. im really happy so far. As you can see, some lower located leaves are starting to get more and more yellow from day to day. As far as i know this comes from a lack of nitrogen which can occur in the last 2-3 weeks before harvest when the plant takes the nitrogen resources out of its lower leaves to shift it towards the buds. i just dont know if i should add some nitrogen nutrients or if its fine to let her like that. Today my Hygrometer finally arrived so i checked my Temperature and humidity. Unfortunately it wasnt like i wished, but still not a big problem. We had warm days with some rain so the humidity is high right know, which also affects my grow. Today arrived Hesi SuperVit which is a nutrient i will add for additional amino-acids and support growth and the quality of my buds. in the next 2 days Hesi Phosphor + is going to arrive and i will be adding it when i am watering the next time, probably tomorrow evening. i got rid of some yellow or brown and dry leaves which were hanging down. The Light is running on 85% (225W), maybe i will add another 5% if she has nothing against it. so far so good, i will update again next week. did not smoke for over 1 month and i get pretty excited when i check my tent and also my plants outside everyday (check my other report if you want) which makes it a bit hard but i like the challenge. have a nice week and stay high
