buds are small in week 5

Your plants have lots of crown leafs. Your plant is focusing its energy into these leaves and its y ur buds are taking a hit. Once pre flower is over remove these in 10-15% stages. Making good airflow through these spaces shouldn't help stomata vents exchange o2/co2 on a molecular level allowing more energy intake. So, once you open it up some u will divert energy into making bud. Wit static lights using energy management is key and defols are essential in growing in a tent Air flow, light intensity, air exchange, energy management. So removing underdeveloped sites way under the canopy id say u have lots of shoots that are far behind your main buds? If so get to doing some lollipoppoing and open the plant up. Its better to have 2-4 main leaves around the top of a node instead of hat leaves that stack up on top of each other and actually slows energy intake.. My point to make low level energy intakes (from lack of proper light /air flow) to less leaves with top intake and focusing those that even though its less foliage its much more productive.
