RQ seeds|NL Auto question

Hey guys ,whats happening?
Im fairly new to the community here and have a couple of questions.
I run a DWC setup with a 300w LED light,and the strain is Northen light Auto by Royal Queen seeds.
here are some photos of the plant,these were taken today,which is about 40 days from seed now.
The thing is,that i've seen people grow this exact same strain and by this time usually they are twice as taller.
I think i might have kept the light too close for the largest portion of the time,might that cause problems with stretching?also,you can see on some of the leaves,and especially the new growth,there is a burning on the edges.
I think it might be caused by the light as well,cuz I didn't really give em any nutes until a week ago and it was a minor dose too.

well,anyhow thoughts are welcome,cheers

Heat stress and light nute burn.Autos do not like nutes as a general rule.

so youre saying just go with straight water throughout?

I grow autos exclusively now and I would say there is nothing to worry about. And no do not skip the nutes just don't over do it.

holy smokes man .... im glad everyone caught that ....... in DWC you have to feed your plants from the go .... really surprised it made it this long on just water

but like hotrod says,aren't autos a lil skeptical about their nutes?
I mean, i rad in a whole bunch of places that you shouldn't really feed you're auto nutes,mainly because they do pretty well on just water,especially in hydro.

>.< right on bro ..... i guess your right ...... and the plant will grow just fine on just water in DWC water .....



now just entertain me for a moment ...... whats the plant eating ? if its only getting water ?

I honestly think that @hotrodharley totally over looked the fact you are growing in DWC and just started feeding at what day 40 ????

You honestly are still wondering why your plants are smaller then other peoples at the same age still ????

how about instead of just going by what other people say you actually do a little research .... I'm not trying to be a dick .... but really think about what you just said ...... the plant literally has nothing to eat ......

definition from wiki
I will highlight keywords so its easily understood
Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only, or in an inert medium, such as perlite or gravel


ok so you have the water ..... what are you missing ...... I'll give you a hint its one of the main ingredients of a nutrient solution

@justugh @bf80255 @HighLowGrow @EverythingsHazy

the " nute burn " is probably a deficiency P or K or both and the lime/light green is a lack of nitrogen ........ just tossing that out there .... but hell what do i know i dont even grow

Nobody has said don't feed them. However,if a photoperiod likes it at 500PPM to start an EXPERIENCED grower, knowing autos don't take to nutes, starts well below 300PPM. Around 150PPM is a good starting point. Up the concentration when the plants show uptake. Much easier to play catchup than to try to calm it down.

And in DWC or not, autos still do not utilize nutes as do photos because of the ruderalis in them. Maybe tekdc911 will start some on DWC at 500PPM and quickly up it and harvest a whopper of a crop.Then share how he managed it.

where are you getting 500ppm's from i never said that ....... but to think that growing in DWC with just water for 30+ days is fine is asinine .... and to over look it when trying to give someone advice just further shows your stupidity

did you even read what OP posted ???

Yes, I did. He already had stated he fed a low dose. That was good and proper.Next step is to move the light back. Like I said.

Do NOT change more than one factor at a time unless you have a catastrophe pending. Back off with the light and watch.

you dont even know how close the light is or was ...... youre assuming it was too close ...... you never asked ...... just giving blind advice ...... Sooo pro

Hell bad advice is better than no advice thats the hotrod way

Right you are.Dumbass me was looking at the plants.

Alright you guys,thanks for the help.
Today i switched the res and mixed in 3ml o' micro n 6ml o' bloom for a 3 gal water which landed at about 850 UG according to my EC meter,which im assuming is about 400 PPM?should I buff it up a lil more?
@tekdc911 how are you curtain that these burns caused by lack of nute rather than overfeeding?
I mean i don't have enough experience with deficiencies to say,but i've checked so photos on the net and it really does look like a nute burn :\.

And btw,everyones input is welcome,and to say weather they are honestly trying to help or not is not up to us,you shouldn't take everyones advice anyway.

cheers.

P-K def shows as a burn .... boron def shows as tip burn on new growth .... you are not just missing your main nutrients you are more then likely missing the macro / micro nutrients as well ... the problem with picking the light up is low light levels makes it easier to burn a plant .....

check out some of the def's on there

there is sooooo much you have too add back to water in hydro to support healthy growth .... I really am amazed that you arent having more issues .... just shows how resilient cannabis really is ...
