Hello all... EHG really is rubbish. I am a licenced commercial grower and have tried and tested almost every 'weed' nutrient out there. And I will tell you with all honesty that the best out there and an all rounder is called Easygro...it comes in Starter,Vegetative and Fruit&Flower. It costs about R800 for a 25kg...little less for the Starter and a little more for the fruit and flower. It also comes in 1kg bags for around R60. It is far stronger in values than most other produces on the shelf and comes with a water buffer added to balance the PH. You can get it from any farmers co-op. It has no harmful heavy metals and no harsh chemicals. I know this because every harvest gets sent for full analysis. There is another product called Multifeed which is very similar but far more expensive. I hope this helps someone.
