If it were me, I'd mix the molasses and guano in with the water for one feeding/watering, then use MG BB at the next scheduled time. The reason is chemical components might impare each other if you mix them all together. Having said that, if you mix them into water and not just mix them together first, then add water, you might be just fine. At four weeks of flowering, how much longer are you going to grow them? Should be getting close to harvest and you should stop feeding and just give water the last week or two of flowering. It might be too late in the grow to add guano unless you want to flower for as long as possible. Go easy with it. Any chance you can put up some pictures?
polishpollack Reviewed by polishpollack on . 4th week in flowering, need some advice Just some advice on adding Liquid Bat Guano (01-10-01) and molasses to my watering schedule; The question I have is, my schedule now consists of 1/4 strength MG Bloom Booster, then plain ph water, MG BB, and so on; can I add the Bat Guano and molasses in with the plain ph water for 1 watering and then the MG BB the next watering or do I always have to use just plain ph water in between the nute watering?
