hey everyone you're here with mark bowell at perfect gardens tv so today i just want to say
congratulations to coherence for winning the two ounce drops of balance uh he ended up correctly
identifying the problem with the recent pictures i was posting and in this video we're going
to get into nitrogen phosphorus and potassium toxicities and breaking them down step by step
if you guys haven't checked out our monthly membership for only 2.99 you get direct access to
our private membership group so far we have over 839 pictures 126 videos 7 files 13 audio files
and a whole bunch more knowledge that we're constantly covering on a daily basis
make sure to hit the join button on the bottom of every video okay before we get started please
remember to like share and subscribe it super helps with the youtube algorithm it's also
helpful to put a comment down below thank you guys alright also right down below in the description i
normally put the google links to this presentation so make sure to take a look and follow along if
the link is not there please put it in the comments below and i'll make sure to include
it with this post getting over 200 comments and over 160 likes this is definitely something i
want to cover with you guys because with over 200 comments there wasn't a lot of people that came
very close and i'm not trying to knock anyone down but what that tells me is that i really want to do
a thorough job explaining these toxicities so that you can identify them later on throughout your own
growth once again guys i really appreciate you guys posting those comments down below
some people get upset that i take a couple days or a week or even two weeks to reply back to those
and it's mainly because i want people to just think about it post their comment i'm gonna come
back to it and through that process i'll normally be doing a nice throw video for you guys okay
so the first one in this picture just like how coherent said nitrogen toxicity there's dark green
leaves and i wanted to show you this right this is and just like in that powerpoint presentation
i provided in the mr grove video right here at the top you'll see excess and deficiency when you come
down to the bottom you'll see one of these being one of the main signs for nitrogen toxicity is
bottom leaves turn lush dark green so as you can see right here there's this lush dark green
happening on these lower leaves and as you travel up it begins to lighten up that being said these
are one of these key signs of how to identify if you're running through a nitrogen toxicity
other ones could include the stem becoming weak foliage becomes weak and again why is it becoming
root weak right the nitrogen we're going to cover this in a few minutes the nitrogen is for amino
acids right that's important for stem and leaf development the plant is growing really quickly
it doesn't have the other minerals it needs like calcium for example to be strong so that's why
when it's growing quickly that's why you'll have weak stems because again it doesn't have the other
trace minerals needed when it's quickly going through cell division as is creating new new
growth and obviously last but not least your end product might taste a little green next picture is
a phosphorus excess new leaves grow thin bladed so as you can see right here this is the top leaf and
it's thin bladed but the bottom leaf right here is pretty wide so this is a really great example of a
phosphorus toxicity new leaves develop inner venal corosis so as you can see right here necrosis is
happening it's very easy to mistake these things as a calcium deficiency or a zinc or a magnesium
deficiency because the chlorosis is happening right where the magnesium deficiency would happen
and as you can see right here the yellowing on the outside of these leaves that also is an indication
of a zinc toxicity but remember the law minimum and the law of tolerance always comes into play
and you'll be able to see it in the plant in one way or another through your general observations
on a daily basis remember make sure to stay the end because i'm actually going to break down the
nutrient line that this gentleman is using as well as a little bit of geeky stuff last but not least
is the potassium excess right so new leaves grow thin bladed once again new leaves are
growing thin bladed as you can see all over this plant new leaves develop intervenal crosses
and i know what you're thinking right like you just said this on the phosphorus yes well
phosphorus and potassium actually have a close relationship so some of their toxicities and
deficiencies will actually show up in the plant very similarly some things that are clear signs
of it though is less internal spacing as you can see this plant is super stacked on itself whenever
i see that as a characteristic on the plant i'm always taking into consideration is it a
characteristic of the phenotype or am i dealing with the nutrient toxicity once again as well
causes calcium magnesium zinc iron deficiencies so that's the seed so we're having a primary
toxicity but it's showing up as a deficiency because it's locking out the other minerals
so let's go ahead and get into geeky stuff nitro nitrogen is an amino acid right so it's used for
stem development leaf development so whenever the plant is growing it's going to be using calcium
when it stops growing it's going to be using less calcium this is important to understand
because when you're using synthetic fertilizer and they're dumping on the urea or other types
of nitrogen the plants will actually grow really quickly and the plants don't have the other macro
or trace minerals needed while they're growing quickly deficiencies toxicities bug problems
mold problems will start normally if you haven't checked out my video on the benefits of nitrogen
please go ahead and do so i won't get into on this video but nitrogen does play an important
role all the way through even through the curing process benefits of phosphorus phosphorus collects
the sun and carbon dioxide to produce atp that's why they call it adenosine triphosphate
so in a sense the plants producing the sugar in a sense as an adenosine but then it combines with
three phosphate groups to produce atp i think personally this is also where a lot of people
mistake when they say or encourage people to be feeding their microbes with sugars right because
technically the microbes aren't eating sugars they're eating organic compounds and the sugar
technically actually had already combined with other minerals to create those organic compounds
i think i'm saying this properly that's why i'm always rethinking the whole sugar process and i
look forward to getting into that whole subject in later videos plants release the o2 and store
energy in the form of sugar or glucose in the root system which later combines with amino acids
to become aka exodites and this is what i was talking about right so the plants producing the
sugars but these sugars are later combining with other amino acids to create different forms of
activities which basically tell the bacteria and fungi to go produce specific trace minerals and
to go and retrieve them and collect them last but not least is the benefits of potassium potash
aids in photosynthesis and food formation helps convert sugars into starches and stores in the
root system for long-term storage increases root growth and improves drought tolerance by building
cellulose and reducing weak stems maintains trigger pressure so it basically helps the water
stay within the plant so that you're not if the plant isn't perspirating crazy and it's actually
retaining its water it's going to be going through less mold problems later down the road and you're
most likely are going to be running into less botrytis so as you can see potassium definitely
is beneficial i always talk about drops balance and law minimum law of tolerance just increasing
your trace minerals more often than not can save you from having a toxicity right because if you
boost up these trace minerals the macro minerals will have a different threshold of tolerance
so at the end of the day i'm always pushing drops of balance for these reasons whether you're a
synthetic grower or your beneficial bacterial living soil grower and also the law of tolerance
we've already talked about this many times if it goes out of these optimum ranges lesser minerals
will become available same thing like temperature if it gets too hot and i've showed you this
in other videos you can actually run into a deficiency problem even though there's more
than enough nutrients in the soil and once again i always love to show this because you could see all
these minerals are playing a part together okay so this grower right here is using the fluoroflex and
as you can see right here that this nutrient line uses urea and these whenever you see the red right
here these are nitrogens i highly recommend not to use why because they fall outside of the natural
nitrogen cycle and i've talked about this in the other video about the benefits of nitrogen so make
sure to check out that video if you're interested in learning more about that but as you can see
here it makes a lot of sense that they might be running into a nitrogen toxicity right if they're
especially if they're using fertilizers that are meant to just mainstream the plant with nudes
same thing because they have a veg1 veg2 and it's a 1404 and a 6 17 25 it's real
easy that if you overdo it or have a dry back period more often than not you're going to run
into a toxicity as you can see it makes sense that this problem is occurring with this grower
because i want to say because he's using this line it's just because he might be using it with tap
water he might have over fed a couple times and before i know it ends up adding up also you as
you can see the foliar feed is the 3910 so they're just nuking the [ __ ] out of this plant anyways i
hope this video was helpful on understanding and interpreting nitrogen phosphorus and potassium
toxicity please remember to give me a thumbs up like share and subscribe have great grow everyone
nature actually has a fast release and a slow release fertilizer program i know that might
sound kind of crazy the fast release comes in the relationship of lightning storms and
when a lightning bolt actually discharges the lightning will split nitrogen bonds
