if you're asking about Fox Farm's 'Big Bloom', you can use it throughout the plant's life, it is a live micro-organism supplement ... I use it, good stuff, evidently ... since it is alive, adding hydrogen peroxide, or using chlorinated tapwater, etc., will kill the beneficial bacteria, and render it useless ... :jointsmile:
the image reaper Reviewed by the image reaper on . are my plants shocked/big bud thread MERGED big bud,add at beginnning or in middle of flowering ? i put it in when i moved them over from veg to flow.Im just not sure if that was right.I also used hum.county bushmaster in the resevoir.I looked at them today and now there totally wilted and a little burn and curl at the end.I know the retailer said that the plants will stress when you add it in,but im not sure if its the big bud or the b.m.,it says to add 6 oz of big bud to my 10 gallon res. that seems to be a lot,should i stick with that Rating: 5
