Personally I respect @RM3 even when I don't agree with him, as he is always respectful even to those worthless trolls that hound him

RM3 merely shares his beliefs and experiences for anyone to use or not use...I can never figure out why people get so hateful merely because his methods are not the "standard"

I also like the fact that when he doesn't know the answer he says so....he's doesn't bullshit or give advise on things he has limited or no experience with

Anyhow @lilroach ...hope you stick around, and just filter out the negative crap that these trolls spew out

growing is as much an art as a science and there is no one right way to do it.we all have different goals and growing environments and what works best for one person may not work well for another. we all benefit from sharing ideals here.but no one benefits from childish fights.I do not agree with everything RM3 says but I do respect him and recognize that I can learn from him

Does more blue cause the need for more N?

That seems to be to broad of a question. I don't know that would hold true for all strains.

More blue causes more growth. The summer sun has more blue so that would lead me to think that they would use more N.

More red cause more stretch. would that increase the need for N?

Too many variables to make a blanket state or answer "yes" to the question.

I think faster growth increases the need for all nutrients. not just nitrogen. the strain I grow is a fast growing slow flowering strain and needs more food than slower growing strains i've tried. I grow with T5s and so do not know what effect increasing the monochromatic indigo ( royal blue) thats LEDs produce would have.more 450nm light would cause the plant to direct more energy toward leaf development but due to the low violet and blue output (430,470nm) of these lights more red and deep red may be needed as well (640. 670nm)

Anytime you increase growth speed they will use up more nutrients.

interesting stuff here a few years back.

https://www.sciencedaily.com/releases/2011/12/111212124657.htm

The team performed experiments in which pregerminated seeds of red leaf lettuce were subjected to various light treatments using blue and red light for one week. At the end of the light treatment (17 days after sowing), the leaf area and shoot fresh weight of the lettuce seedlings treated with red light increased by 33% and 25%, respectively, and the dry weight of the shoots and roots of the lettuce seedlings treated with blue-containing LED lights increased by greater than 29% and greater than 83% compared with seedlings grown under a white fluorescent lamp. The shoot/root ratio and specific leaf area of plants irradiated with blue-containing LED lights decreased.

At 45 days after sowing (DAS), higher leaf areas and shoot fresh weight were obtained in lettuce plants treated with blue-containing LED lights. "The total chlorophyll contents in lettuce plants treated with blue-containing and red lights were less than that of lettuce plants treated with florescent light; the chlorophyll a/b ratio and carotenoid content increased under blue-containing LED lights," the researchers wrote. Polyphenol contents and the total antioxidant status were greater in lettuce seedlings treated with blue-containing LED lights than in those treated with florescent light at 17 DAS.

so why doesn't 3 band (450,630,and 660nm) grow good pot. nasa found that adding green light improved performance and this study acknowledges that other studies found different results.what is valid is what a preponderance of what test show. you can't simply pick and choose studies that agree with you and call that science

Michigan.....I've been around awhile and it's been my experience that when someone always seems angry at others is actually anger at themselves. I hope you find the inner peace you're lacking.

No reason to leave. I went back and removed my post.

This is still a good place to learn and share knowledge. There will be trolls and ass holes everywhere.

How about some crispy smelt?

Mmmmm smelt, haven't had them in a while ;). My first job was charging a buck per person to fish along our creek. People would get green garbage bags full and complain cause this little kid was asking for a dollar lol. Then there was the processing plant later ..... scissors :). Me and my brother would sell 5lb bags cleaned for $2.50, that was fun cleaning those little bastards for a week till the run finished lol.

Since the summer sun has more blue.. More blue causes more vegetative related growth/root development.
Since the fall sun has more red... More red cause more flowering related growth.

As it has stated once already... Regardless of the light. YES! Growth in general causes a need for more nutrients/minerals/chemicals. Just not explicitly Nitrogen.

is there a certain amount of skull density, that information must pass through, before you are willing to except the answer to the question or must the answer be written in manner that even small child can understand?

Stop focusing solely nitrogen. Remember nitrogen is also a small part of the air we breath. Too much nitrogen will cause problems with growth regardless of the light the plant is receiving.
