🇩🇪Purple cookie kush 1st grow

Hello, Day 29 of flower today. She is packing on some trichomes since 2-3 days and it’s getting more everyday. Buds are growing and starting to look like they should. The smell is not that strong but if you walk by the opened window you smell that there is a weed plant somewhere near. The trichomes are sticky and the smell is hyping me up like crazy. Weight was okay today, I will water again tomorrow with 6-7 Liters without added nutrients. Some bottom leaves are starting to get a yellowish colour which kinda concerns me, but I’m far away from panicking. Estimated flower time are 50-60. my light is running on 85% which is 225W / 35cm distance to the canopy. I added those extra 5% power yesterday and we will see if she likes it. Maybe I will buy additional phosphor booster, but I have to gather some information first. I the next couple days I will also get a hygrometer to check my humidity. I can’t change it but I think it’s good to know for the next grow. The temperature is measured via an infrared thermometer, leaf temp was 18°C night and 23°C day temp. If you have questions or recommendations for me, use the comment section :) Greetings and stay high
