Strangely I'm having to mix 2 tbs (30 ml) of their Grow or Bloom hydro nutes per gal to get the right results. Not only does Botanicare only call for just 1 tbs/gal, but on other forums I've read the same recomendation claiming excellent results. When I try to use this ratio my 2 month old plants show noticeable nute deficiencies. I'm a veteran grower and conditions are otherwise ideal, so I can't figure out what's up. It's pricey enuf stuff without having to use twice as much to get good results. I have no complaints with it other than this. Anybody have any ideas or have experienced anything similar?
