Hello, I'm currently 4 weeks into flower, my plants are root bound in 2-3 liter containers. There are roughly 4-6 weeks left until they finish. What would be the best way to increase yield? I have 1000 watts hps about 6-8 inchs from the canopy, no burning. I don't use molassas or co2 in my enviroment, as well as a small air exchange rate. I'm thinking about adding about 8 2 liter bottles of fermenting yeast for the remaining time, adding molassas to the soil, and possibly doing root transplants into 3 gallon bags. I want to add co2 and molassas at least, I'd rather not root transplant this late into flowering unless I'll see substantial results. I have a good foxfarm nutrient regiment, a very high 20,000 lumens per square foot ratio. Help me boost this yield!
