Hey Az thanks for the response, i just read on hg's website and they recommend the bud xl first site of flower...but ill do what you said and hit it right after the pk 1314 along with the sweet...my line will consist of canna ab, cannazym, pro silicate, gh rapid start(supposed to be like rhizo or roots excel any advice on this? not sure if it works the same or not), calmag plus, pk1314, little epsom salts in first couple weeks of bloom, bud xl and the sweet....... and now maybe the budswell? who makes this and is there any product you could compare it to? cheers!!
