Wondering if someone can help me?

My lower leafs are turning yellow and the other leafs are curling in at the tips.

I’m not the one that can help. But if possible take a picture of plant in natural light and post.

Burnt tips and clawing leaves are generally a sign of nitrogen toxicity. Have you been monitoring ph and ppm?


My pH is between 6.5 and 7 but I’m a first time grower and I’m not really sure what you mean by ppm

How close is your light fixture to the canopy? Looks bleached almost.

@dbrn32 is referring to the amount of total dissolved solids in your runoff, to gauge how much is there for the plants to eat.


They do look bleached. More times than not they seem to bleach really easy when there is already some necrosis. I would also be curious about light distance.

Ppm or tds is a measure of solids, ie. Salts, metals, minerals etc. it’s how we watch how much we feed our plants. In soil It’s typically measured before and after feeding.

If you could give us some clear pics under normal light it would be helpful.
Also, please fill out a support ticket.

Also Multiple pictures of the plant in natural light would be helpful, can’t see anything thru the burple color

Also noted that you said 6.5 to 7ph
I am assuming you are in soil so sweet spot is 6.5ph and vary from 6.3 to 6.8 ph if at 7 then you should flush it will really be a issue in middle and late flower and decrease yeild and then has to recover and take longer to finish for harvest


Welcome to our world of growing here at ILGM and to our awesome community.

what you have there is the start of "NIUTRIENT BURN "


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. 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.

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 what they look like in better lighting

Looks thirsty/hungry! How/what are you feeding and how often?

General Organics box of nutrients once a week and they have been getting watered almost everyday

In 5 gallon pots how much water should I use to flush each plant to make sure they’re completely flushed? I have 9.

The rule of thumb is 3-5 times the volume of the pot. What are you runoff numbers like? Are you wanting to flush to correct an issue? How much water are they getting daily? Is it coco? Filling out the support ticket @Drinkslinger posted above will help us out a lot.



Here are a couple of piss of under watering


Over watering

Over watering is one of the biggest mistakes new growers make, reason for this is, because they feel
the need to give there plant everything and will overdue a lot of things and one of them is over
watering. By over watering your plant you soak the roots so much, they can’t get enough oxygen
and slowly die. The plant shows signs of over watering by: Wilting, droopy look, yellow and or dead
leaves falling off, which includes leaves that don’t look dead falling off. One of the best ways to
tell how NOT to over water is by, picking up the pot when it is dry and then picking up the pot after
you water. (This is a reason why it’s smart to use light pots.) When you water, you want to water just
enough to where you see a bit of water coming out of the bottom, not gushing or pouring out
. Just enough to see a little bit, then you know the plant has enough water. To prevent over watering
you can either: add more perlite to your soil, add hydrogen peroxide to your water for extra oxygen,
all the while killing bacteria if any in the soil. After watering, wait a few days to water. Mj plants
like a good watering and then a couple days to dry out in between watering. So it’s very easy t
o over water. Besides the weight of the pot, another way to test if your plant needs water is to stick
your index finger a couple inches into the soil. If the soil at the tip of your finger feels almost dry,
then it’s time to water again. The top of the soil should be allowed to dry out between waterings if it’s
still moist the plant does NOT need watered. You can also use a moisture meter which will tell you the level
of moisture down in the soil. You can buy them at most garden supplies or hydro shops.
Here is a picture of what over watering looks like:

Do you have like 50 plants? That’s a lot of lights.

No. I have 9. I was told more watts the greater my yield will be

The soil doesnt look overwatered at all. Grab a TDS meter off of Amazon(10 to 15 dollars) so you can see what your runoff numbers are. Whenever you have the meter it will give you a better understanding at what is happening below the surface. She is definitely heavy on the nitrogen but I dont think I would necessarily flush, it’s just gonna strip EVERYTHING out including your macro nutrients.

If I was you I would grab a TDS meter, feed with a gallon of water and collect the drainage aka runoff. Measure the ppm/ph and then go from there. If you see your ppm in the 1500-2000 range then I would just give water only feeds until the plant eats alot of it.
