What's going on with my leaves

First time grower

Leaves I cut off

Strain; NA seeds


PH of runoff or solution in reservoir 5.5ph

What is strength of nutrient mix? 1/4 tsp floragrow and floramicro per gallon


Light system, 300w led

Temps; 68-82°f

Humidity; Day, Night 42-56

Ventilation system; Yes, NA

AC, Humidifier, De-humidifier, no


Leaves on play everything same but strain strawberry cough

I just topped off my water with ph balanced water no nutrients will update on change if any

This is the plant with leaves cut off from

Looks like Nute Deficient to me, may want to up the feeding a smidge and see if that does it.

Raise your ph to about 5.7-5.8 5.5 is okay but if it swings down any it will begin to start to lockout. Looks like you might have a small calmag issue. Do you use calmag at all?


Will get some calmag tomorrow and mix it in thank you both for the suggestions

What do you think @Donaldj

Got some calmag and added it in with a higher pH level today some more spots showed up as well

Keep adding Cal-Mag, you have a calcium deficiency. You’ll see an improvement on the new growth.


Agreed, I am unsure how it works with hydro or how much to add. There should be some direction to follow on the back of the bottle.

There was some instructions on the bottle I followed them. How many days does it take to show Improvement. Also thanks everyone again.

And will the spots on the leaves stay or clear up.

The damaged leaves will not clear up, look at the new growth to see improvement.


I believe your problem is:


Here is a pic

As you stated you followed the instructions on the bottle and sometimes depending on the strain can be to much.

Nutrient burn

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

Would it be best to do a total flush new water add 1/4 tsp floramicro and 1/4 of calmag

Cal mag or no your ladies look hungry and are suffering from multiple deficiencies start by adding more than 1/4 tsp per Gallon which is 1/4 of schedule for early growth should be 1 tsp 5ml each per gallon Micro has all your minerals in it iron zinc Cal mag etc. not saying some plants don’t love extra Cal just that if you aren’t feeding enough base nutrients not much point adding extras

Alright well I did add more nutrients I’ll wait and see what the new growth looks like and the biggest plant you as you can see is only 7 in about

First picture with yellow background floramicro second one with red is the calmag
