Rusty,
"Lawn nutes" Well lets approach from this angle. If you just give a certain fertilizer you change the osmolality of the water that is contained in the soil. By giving a fully balanced fertilizer the plant is able to not have lockout and pickup what it needs and wants.

I have used just about every sweet and flowering and veg and whatever nutrients you can buy. I think in hydro that stuff is great if well balanced. The only nutrient I noticed any difference with was pure carbohydrates (sugars) without any NPK. Even then this can mess with the osmolality and the plant gets what is commonly known as lockout. (Actually some of the stuff sold to flush is pure surgars.)

I am not saying don't do anything. What I see across the board here is overuse of nutrients first, and overwatering second. Of course you have to have good soil to start with. I have used MG in the past, I like Fox Farm better. I get moisture retention that works right for me in my environment and pot size and grow room, etc.

The last thing folks do is skimp on lighting. Folks need to chill, especially new growers, and let the plant show them what it needs. Sure sometimes the plants need a nutrient. Experience teaches you what it needs. Again often we lock out stuff by over doing things.

Yep, sounds really unsophisticated to use simple ole 16-16-16. It has taken me lots of years to learn that, but it just flat works the best for me.

And I appreciate your educated approach to questioning my statements, thanks for the respect.
