Lights and nutrients

Are nutrient feeding schedules based off of what wattage of lights you are using? I was advised that they are based off of 1000 watt lighting and that I use half because I'm running a 400 watt hps. Thanks in advance!

Lol who told you that? I've never heard anything like that. I guess if you think about it more lighting usually means bigger plants which means more nutes. But I wouldn't go as far as basing my nute schedule around the wattage of my lights. Just look at your plant, she will tell you when she's hungry :bigjoint: I usually start out at 1/4 strength nutes when they show signs of being hungry. If you base your nute schedule on your light wattage be ready for a bumpy ride especially when you switch strains up. Every strains needs are different no matter your lights

Thanks man. It was on another thread. I had never heard that before, just wanted to get some clarification.

in the few years I maintained a cool flood/drain hydro I used a different
nutrient system each cycle and followed directions to the T. All of them performed really well
and it came down to cost and ease of use for my final choice. Advanced Nutrients, Technaflora, DutchMaster Gold were notably successful every time. my environment/grow habits were always dialed in while doing this and I believe this is usually the major culprit when plants fail. I never added anything, no corrections or fixes, didnt buy into any others that were not required per instructions.

Cool bro I might try something different after this grow. I was referred to emerald harvest by a friend. This is my first grow but I think it's coming out good.

Advanced nutrients are very easy to use :bigjoint:especially in hydro! I haven't had to ph my Rez once since AN

Actually basing your nutrient strength and irrigation/fertilisation times is DIRECTLY related to the amount (wattage) and type (spectrum) of artificial light. Along with temperature, carbon dioxide levels and relative humidity.

So basically what I'm getting out of the responses and from my local store is that it's true but it's not true.

First off it would do you well to get a TDS/PPM (actually an EC) meter. This tells you how strong you make your fertilizer solution. And a pH pen is a good idea as well. If your serious abouy growing indoors with the common bottled nutrients the grow store sells...your gonna end up getting these 2 meters anyways. Might as well start now. They dont have to be the expensive ones either.

That's exactly what my local guy said. Should I order the $10-$20 meters off of Amazon? His start at $50 in store.

your plant will only grow to its weakest resource.
if your light for instance is your weakest resource then of course your plants will require less nutrients to thrive to their potential.
cool thing is you already know ever necessary resource now decide which one you're going to short your plants, that one will be your limiting factor, no matter what you do nothing will improve until that does.
higher heat means faster/greater metabolism, more nutrients, more light, more c02 more water too, but does this mean to increase your heat? no ! not unless you can also provide all the new necessary resources in a timely manner.

my first harvest was with a 400 watt mh, I followed directions, full strength with technaflora, then AN, no issues at all. I had ac, heat, dehuey, c02 also. I put all this into a huge room and repeated the success. full strength per directions these performed very well.
my 1k lights penetrated my canopy even deeper, so I could grow bigger yielding plants...they didnt require stronger ppm's though.
hope that puts things in perspective for you
