This s what it is


                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          ?Nutrient Burn is one of the MOST common mistakes a new grower makes,

The reason for this is, because a newer grower will use a chemical nutrient
most of the time and listen to the directions on the box. This is a NO NO!
Depending on the age of the plant, size, strain and soil mixture you are using
also has a factor. There is no set guideline when using nutrients, but I can
give you a good example to start out with so you will not burn your plants.
It’s always good to start out light, rather than feed heavy. Remember you can
always add more later, but can not take out when you added to much. Chemical
and Organic nutrients differ. Chemical nutrients are more readily available
and can burn way easier than organics can. Organics are easier for a newer
grower to use, most of the time, and lessen your chances of burning your plants.
I recommend not using more than ½ teaspoon of chemical nutrients per gallon
of water. Unless the plants are very big 5 feet+, then it’s safe to use 1
teaspoon per gallon of water. When your plants first emerge you want to wait
at least 2 weeks before feeding your plants, unless your plants are in a soiless
mixture, like pro mix. The cotyledons (its first set of round looking leaves) are
what give the plant its food until they get the first 2 or 3 sets of leaves. If
your plants are in a soiless mixture and are over the first week of age; you can
feed a weak amount of nutrients, like ¼ teaspoon per gallon of water. Soiless
mixtures are different from soil plants and soiless plants need to be fed more
when using this mixture.

I also recommend not feeding more than 1 time a week if using ½ teaspoon per
gallon of water for chemical nutrients. You can feed every other day,( this
goes for chemical and organics) at very weak amounts, but doing this may contribute
to over watering, and for that I do not recommend feeding more than once a week.
Some people feed 2 times a week using like ¼ teaspoon per gallon of water… Use 1/4
strength for first feeding and then go up to 1/2 strength from the 2nd feeding when
using chemical nutrients. It’s very easy to overdo it. When using organics, depending
on which one you’re using, I recommend using 1 teaspoon per gallon of water. When the
plant gets bigger you can work your way up to using more nutrients when the plants
get bigger.

As for soil mixtures, there are a lot of different kinds of soil’s out there. Using a
rich soil mixture is not recommended for seedlings. Seedlings that are under 2
weeks of age you do not want to start them in rich soil, using a seed starter
mixture is one of the safer ways. Seed starter mixtures are weak in nutrients,
so it will not burn the seedlings but will provide them enough to get past seedling
stage, but the downside is you have to transplant into a better soil mixture after 2
weeks of age. If you decide to start with this mixture, do not put your seedlings
into a big pot. Start them out with using a cup or a small pot.

Nutrient Burn causes leaf tips to appear yellow or burnt. They can also be brown
and twisted and crispy looking. Depending on the severity it can show many different
symptoms and shows on lower part of the plant when its young, at older stages it
can move anywhere on the plant.

To fix the problem when you have Nutrient burn, you want to flush out the plants
with lots of water.


Soil should be flushed with lots of water, Use 3 gallons of water per one gallon of soil.
Flush very thoroughly, after plant recovers usually after a week, you can resume using
nutrients after a week or a week 1/2. When you flush your soil, you flush everything out,
a lot of nutrients go with it, including the soil nutrients.

Hydro `````````````````
Change out the reservoir, flush out any lines and clean out the entire system and
replace with plain water for the first hour, then start out with lower parts per
million (PPM)
Its good to clean out your system every 2 weeks and replace with fresh water and
nutrients. Some people change everything every week!

Ahh, nute burn! Stop this by not adding to much chemical/organic nutrients to your
water,foliar feeding. DONT feed more than 1 time a week unless using weak amount,
use 1/4 strength for first feeding and then go up to 1/2 strength from then on when
using chemical nutrients. Its very easy to overdo it. Causes leaf tips to appear
yellow or burnt. NEVER give nutrients to plants that are under 2 weeks of age, at
this age the soil nutrients are enough to suppliment them untill 2 weeks of age or
more depending on how good your soil is. Using ferts before 2 weeks will almost
likley kill your plants.

THIS IS MAGNESIUM ( Can you see the difference {



Hmm even with inside of new growth yellow from inside out


Very interesting. I have 4 plants and the white rhino is the one giving me the issues. They are 10 days into flowering and have been feeding NFTG I have been on a feed feed recharge/slf-100 then repeat. I did a slurry test and my ppm were in the low 200s so I would think I would need to feed more. I know that just adding more nutrients isn’t the way to go. Last watering I only watered with plain water no nutes. So for this plant it was do to water with sechduled nutrients tonight. Should I just water with plain water again? or continue with schedule ?


hmm It is the last to ad just before pH the water.


Just water @Smokin_ernie just water trust me that’s the beginning of NUTRIENT BURN


Ok for sure I will trust you. thank you!! How long do you typically need to wait before returning to nutrients?


Two waterings in your case. Thats because you caiught it in time. But when you restart use only half strength and increase slowly


sweet thanks a bunch. This white rhino is the only one that has had the issue but will keep an eye on the others.


@garrigan65 let me ask you this would nutrient burn cause leaves to curl like a canoe? or could that be from the light. I am pushing the height limit on the LED cob they are about 12- 14in from canopy and with things stretching they getting even a bit closer.


i believe it is the lights,back em off a little and see if they will flatten back out…



The burn will creep into the center of the leaf causing it to curl and dry up. It depends on the specific nutrient that is in excess. For example, too much nitrogen causes leaves to curl downwards and too much potassium creates brown spots near the edge of the leaf. Either way, nutrient burn may potentially kill your plant or lead to it having a strong chemical taste.


You just got to remember that each strain has different genetics and won’t take the nutrients the same .
So it’s better to start each strain at 50% and work your way up and watch how the plant reacts.


Learning more and more each day. thanks @garrigan65. I was looking last night and she looks as if she is improving. I was also checking much closer to the other plants and found one to have a slightly and very slight tip discoloration. Well learning how these new nutrients work for me and how they act to each strain a bit different. Buds are starting to form on all except the bruce banner it has some white hairs.



That is so true every day is. And what you just found out will help you SO MUCH in the long run it isn’t funny


So little update… got me self a kerosene pump battery operated. Does 5 to 6 qts per min. This is going to be a game changer for watering and for any future flushes. I was thinking of picking up a small shop vac to do with flushes as the one I am currently using is huge and makes it very crowded. Then on top of that I have about 8 - 1gallon jugs floating around. So know with this pump I will be able to use 5 gallon buckets. Not only will it help with the watering but mixing the nutrients be able to control mixture of 1/2 or 3/4 strength by mixing in the buckets.


that will help the ol’ back for sure!


and my knees. I use a foam pad to kneel on but it doesn’t really do the trick.


chit dawg,i would not be able to do that…lol

This plant is yellowing/pale green leaves and yellow center with some brown spots. I have watered the past 3 or 4 waterings with just plain water because it was said to have nutrient burn. Last watering was with recharge and slf-100 with a runoff of 2000ppm. Not sure why it is not feeding or if it needs to be fed. There has been talk of a possible potassium issue? Nutrient burn?

@Usmcjojo @Hogmaster @latewood @raustin @Screwauger @Willd @Covertgrower @Countryboyjvd1971


I’m no expert by any stretch but it seems like they are in need of N? But you have high Runoff so Most likey they are getting enough… never used NFTG nuttients though… good luck , curious as to what the issue is… @Smokin_ernie
