i tend to be a nute junky and most have at least 3 or 4 co's line of products.. started with gh, switched to fox farms, then an's stuff, and recently got a seven bottle sample pack from botanicare that i'm really liking thus far...
the thing i don't care much for with an's stuff is that i was mixing upwards of like 12 or more bottles at a time just for one feeding.. i was beginning to feel more like a chemist than a botanist, and it got rather old rather quickly...
with the botanicare stuff, i am just using the pro veg or bloom, which ever is needed for the time of growth, the liquid karma, sweet and i have always used their cal / mag as well, so i'm still using that now.. and that's it.. much simpler than an's stuff,and i haven't had any issues with their stuff yet..
