Yeh we have different brand nutrients here in Australia, I'm not sure if I've seen that one before. I know there is dutch master, advanced nutrients, canna, general hydroponics, green dream, growth technology, rock, house and garden and isn, to name most of the ones at my hydro shop, haha
you know they all do pretty much the same thing and have the same price, so to be honest I'm not sure there is much difference between nutrients other than some are designed more specifically for soil, coco, hydro etc
your girls are looking nice, after I boosted the nutrients on my system last night I checked this evening and found that one of the smaller plants had nute burn, sigh...had to dump half the reservoir and fill with ph balanced water, so I guess don't be over eager to increase your nutes to quickly for smaller plants, benefit of soil grows, controlling nutes for each plant, my system is one reservoir and every plant gets same nutes, so yer...will hope the nute burn does not spread down the leaves or affect the root system
