This might not be the best place to post this, but here goes. I have two plants, Dinafem Blue Hash, 8 week estimated flowering time. Im growing in bubble hydro system. They have been flowering for like 18 weeks. Way too long, something has to be up. I havent done anything to really stress the plants this grow. Its been fairly smooth sailing. Im using 2 90W LED UFO's. While they worked fairly well for veg they dont produce the girth that they should when flipping to 12/12. And it takes forever before they pop pistils. Prob 3 weeks or so to show pistils. Im wondering if it is safe to assume my problem is with the lighting? Im considering switching to 250W MH/HPS, this would give me like 55w per sq ft, and lumens vary based on bulb. Would making the switch help, or am I just an idiot?
