Thanks for the reply BayLee, ive seen on another forum the same thing, Plant Magic is big in the UK, Old Timer Bloom is what a lot of Old School growers use, its organic. They did a side by side, these growers have never PHd a thing in their lives and never will, they say the compost will buffer PH, their grows are absolutely stunning. Anyway, they used Medi-one in parallel with the Old Timer, but couldnt work out why the Medi-one didnt perform, apparently it was because they did not PH. They couldnt understand it as Medi-one is organic, the same as the old timer. I dont PH anything, so a bit worried I might mess my plants up or maybe I should just PH stuff instead lol. Looking at the ingredients it looks superb, ive heard it smells bad but in a good way, bit like biobizz fish mix, thats a stinker too!
