i saw a shitload of advanced supplements and nutes in an online shop yesterday that i didnt recognise at all, i guess this is what u guys are on about.
gonna be a nightmare re adjusting to new nutes, not meaning to sound fussy or anything but for example when i mix the old gmb up as per according to the guidelines on the feed guide - its waaaaaaaaay stronger than the guide predicts in ppm.
i also cant feed heavier than 1.7 eec, my plants burn if i try.
i suppose its my growstyle + enviromental factors what contribute to this..
i use the advanced range and am soon to be ordering new nutes, i was pricing them up the other day, i guess ill be giving these a go.. tentatively LOL
