Well I have been enjoying the Reiziger A & B grow and bloom , seeing noticeable difference each day , I am running the 3ml per lt which is giving me 600to 700 ppm 6.1 ph , that’s a basic straight feed by the time I’ve added the cyco range they seem to be doing what’s required , in my mix I add , silica 2 ml per lt , Cal /mag 1.25 per lt , Sugar Rush 1ml per lt , Supa sticky 2.5 ml per lt, I have cyco swell as well ill add that last 2 weeks before flush for me that’s week 9 & 10 . I like the Reiziger being slight low in N , I run passive air intake and Air is 78% N . If you looking for a good A & B grow n bloom give Reiziger a blast . OD. Just don’t sit there look through my latest grow pics .
