For me itâ??s a definite NO! I wouldn't use it at any stage.

The reason is because of what I observed from one guys various grows. It may have been his strains, lighting, nutes or another part of his environment but his buds were virtually nothing but veg leaf. These unattractive leafy buds also seem to contain little, if any trichomes and probably tasted like lawn clippings. See the picture. Like I said, this may have been due to other factors but he tended to use a lot of Superthrive.
