The only one of those that I have extensive experience with is Advanced. 20 years using them and always get great results. Even easier now with the pH Perfect technology. I've mainly grown DWC or soilless with them using RO or distilled water only. Since the switch to pH Perfect some years back I have never checked pH and never had issues I could say were pH related and I'm talking at least a couple hundred plants. Sometimes I've fed too much or too little but never had weird pH type problems.
All I use is the 3-part, Big Bud for flowering and some Rhino Skin for some silica. Any CalMag will do and I also use some Epsom Salts. I've tried a few of the other supplements but never noticed anything that was worth paying extra money for. They make some specifically for coco too but I never use coco so not sure what all they have. Can't get coco locally but ProMix HP has been around the last 10 years or so and I love it. Straight out of the bale and water in with half strength nutes to start with works great. I rarely go more than half strength unless it's a heavy feeding strain then may go 3/4 at 3mls/L every 2nd watering. I mainly go half that or even 1ml/L each watering to even out the feed. In DWC I may change nutes once after the stretch but mainly never change the nutes the whole grow and just monitor the ppm levels to adjust how much I feed them.
I have a buddy that swears by REMO nutes. He grows professionally and started using them about 6 months ago. I just picked up a small version of their Supercharged kit that I won in a draw at the hydro store in the city. I actually won it last Nov but didn't make it out to the city until two weeks ago and picked it up. All the same 7 bottles but 250ml of each instead of 1L each in the full sized pack. I'll be doing a side-by-side with them and the AN stuff to see how it works out. Also some MegaCrop v.2.0 one part nutes that I also won but on a pot forum and so far I'm liking them too. You should check them out. They're making a 2-part version of their dry nutes now and have a few supplements as well tho I'm not a big fan of tossing a lot of those into the mix.
I have no experience with the Green Planet or Emerald Harvest but they should work too.
If you hate screwing around with pH then go for the AN.
Hey bro thanks for taking the time out and sharing your experience.
I'm liking the idea of soulless medium, it's more easily manageable. I would assume this was coco with a mix off perlite or hydroton.
Yes the ph stability talks for itself as I think this takes away 70 percent off the headache away.
So was the ph perfect sensi grow and bloom perfect for coco. And I'm sure there was need too add cal mag?
You mentioned pro mix, so know I'm confused haha
I thought soiless was coco. And I'm assuming you've only tried to 3 part, big big bud, silica.
So did you friend use advanced first and then make the switch too remo?
If I do try remo I'm kind of worried haha about the ph. But if I do 30 percent mix with coco I'm sure the medium could buffer it out. But tgeres also a chance of nute lockout in coco.
It also defends how chelated nutrients are so they do t too much salt build up behind.
