I've been using Advanced Nutrients for years now....and at first i loved it. But they've def changed the way they make shit nowadays. I've noticed it over time. Like their pH up and down for example...used to be hella concentrated, now it seems watered down. And i'll order shit directly from them, or go to the local shop and pick it up only to find when i need it that theres sediment in the bottom. I think the taste is lacking too...so i wanna try something different. I think the last thing i used for any amount of time before AN was BC nutes. Been thinking of trying PBP, beats the shit out of mixing up all of AN's stuff. So what are you using? If you use Pure Blend, how long have you used it and what are your thoughts? I'll be dripping into rockwool slabs in case you were wondering...
