Can anyone give me any advice on stimulating growth during the flowring cycle? the buds seemed to have stopped getting any bigger
Well, How many days into flowering are you? Use a bloom boosting nutrient solution...I use GH Nutrients, you can use an array of things. -C
I feel guano is sketchy advice, as most people just use a fert with an NPK ratio that goes little-big-little (the middle number is higher than either of the other two numbers).
Well if you havent used fertilizers yet? Doesnt that come to mind without asking this question? Perfect Bud Stimulator = Bloom Fertilizer.
