Hesi Hyrdo Growth nutrients - Anyone have experience with these?

The dude at the hydro shop highly recomended it. He also said that they immediately sold very well with out any advertising or promotion. So.. I got it.

The thing is, when he sold them to me he said that you should use more than it says in your solution. He said to use what it has as full strength for youngens, and more for mature plants.

I decided to play it safe and used 150ml in a 10 gal res (full would have been 200ml) and i'm seeing a tiny bit of yellow tips. SO... fuckin glad I did'nt use full strength... .but does anyone know anything about these nutes? was he right, and somethin else is givin me yellow tips?

Over nutes are yellow leaves tips. Cut back some more. If you just changed rez, take some out and replace with PH water. It all depends on the strain. Some don't like heavy nutes and some do. Good thing with hydro is you can adjust quick when you see a problem.
