I have an arroponic set up, try to keep PH at about 5.5. I have a strain that flowers in 8 weeks. Im using a 600 watt HPS for light, and flora nova nutes. Ive added beastie bloom about half way through as it helped produce denser buds in previous soil grows. Im approaching week 10 and for the last 3 or so weeks it seems as if the buds have not goten any bigger. The tempeture is cooler than it should be but has been cool the entire time, usually about 63 with the lights off and about 73 with the lights on. Humitity is in about the 50 to 60 percent range. From what i told you does anyone have any theories why the buds have seemed to stop growing. Keep in mind although they are generally small they are pretty dense, and the leaves on the plants are green and healthy.
