Hi, For those of you in the UK you're probably familiar with phostrogen, it's available in all garden centers and some hardware shops. When I started growing all those years ago I used this as its got all necessary macro 16:10:24 and micro nutrients and its cheap. About a year ago I switched to H&G A and B coco and to be honest I wasn't to impressed so I'm going back to phostrogen. I've decided to show how good this stuff is by showing a grow. I'm 12 weeks into growing an afghan kush in coco coir drain to waste. As I'm using coco coir I add 1 mil of calmag per litre to satisfy calcium and magnesium deficiencies that are common nutrient problem with coco grows. A 2 kilo box of phostrogen will cost you between £9 and £10. I add half a teaspoon of phostrogen which is 2.5 grams per gallon of water. My tapwater is 300 ppm, with 2.5 grams of phostrogen and 5 ml of calmag ppm is 800 ppm, runoff is 900 ppm. As you can see plant is healthy.
