Your going to need to take some pictures under normal light. It’s to hard to tell the health of a plant under a grow light.
You can turn off light and use camera flash.
My thoughts would be looking at the pictures with the leaves turned straight down and tips burnt. Back off on feeding anything for a week or two just pH water see if youcan get the leafs to stand back up.
I think your problem might be in the dirt. You don’t mention what kind of soil here using and your pH should be 6.5 , also your light should be MH for Veg and HPS for flower., might be too close because your nodes are so tight. Hope you get it worked out.
Looks like coco. What is that purple hose into the coco? is that hooked to an air dome? NICE!
Plant just look like it’s hot, but 26C isn’t so bad, so maybe light height? Watering with coco can be tough since it dries out fast. Also looks like you have some nute tip burn. What are your PPM’s in/out?
hi guys thanks for you help i had someone look at them who knows he said ive accidentally over feed them so ill dry them out
DOSE ANYONE KNOW HOW MANY LITERS I SHOULD BE FEED THEM A DAY THERE IN 15 LITER POTS IN CANNA COCO THANKS FOR ALL YOUR HELP PEOPLE
someone told me to put some holes in my coco to dry them out faster is this true
Looks like the nitrogen claw go to mh for veg and or one light hps and one mh other than that nice dark green
I’d flush them if it were mine!!
No, what the problem is and it’s not from over feeding either.
IT’S… Magnesium_Deficiency
HERE ARE 3 PIC’S TO SHOW YOU
Below the pic’s is how to fix your plants
Magnesium (Mg) - Micronutrient and Mobile Element
Magnesium helps supports healthy veins while keeping a healthy
leaf production and its
structure. Magnesium is significant for chlorophyll-production
and enzyme break downs.
Magnesium which must be present in relatively large quantities
for the plant to survive,
but yet not to much to where it will cause the plant to show a toxicity.
Magnesium is one of the easiest deficiencies to tell… the green veins
along with the
yellowness of the entire surrounding leave is a dead giveaway, but
sometimes that’s not
always the case here. In case you have one of those where it doesn’t
show the green veins,
sometimes leaf tips and edges may discolor and curl upward. The growing
tips can turn lime
green when the deficiency progresses to the top of the plant. The edges
will feel like dry
and crispy and usually affects the lower leaves in younger plants, then
will affect the
middle to upper half when it gets older, but It can also happen on older
leaves as well.
The deficiency will start at the tip then will take over the entire outer
left and right
sides of the leaves. The inner part will be yellow and or brownish in color,
followed by
leaves falling without withering. The tips can also twist and turn as well
as curving
upwards as if you curl your tongues.
Excessive levels of magnesium in your plants will exhibit a buildup of toxic
salts that
will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can
get locked
out by having too much Calcium, Chlorine or ammonium in your soil/water.
One of the worst problems a person can have is a magnesium def caused by
a ph lockout.
By giving it more magnesium to cure the problem when you are thinking you
are doing good,
but actually you are doing more harm then good. When the plants can’t
take in a nutrient
because of the ph being off for that element, the plant will not absorb
it but it will be
in the soil… therefore causing a buildup. A buildup will be noticed by
the outer parts of
the plant becoming whitish and or a yellowish color. The tips and part
way in on the inner
leaves will die and feel like glass. Parts affected by Magnesium deficiency
are: space
between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.
Problems with Magnesium being locked out by PH troubles
Light Acid Soils, soils with excessive potassium, calcium and or phosphorus
Soil
Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
Magnesium is absorbed best in soil at a ph level of 6.5-9.1 . (Wouldn’t
recommend having a
ph of over 7.0 in soil) anything out of the ranges listed will contribute
to a Magnesium
deficiency.
Hydro and Soil less Mediums
Magnesium gets locked out of Hydro and Soil less Mediums at ph levels
of 2.0-5.7
Magnesium is absorbed best in Hydro and Soil less Mediums at ph levels
of 5.8-9.1
(Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.)
Best range for
hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges
listed will contribute
to a Magnesium deficiency.
Solution to fixing a Magnesium deficiency
Any Chemical/Organic nutrients that have Magnesium in them will fix a
Magnesium deficiency.
(Only mixing at ½ strength when using chemical nutrients or it will c
ause nutrient burn!)
Other nutrients that have magnesium in them are: Epsom salts, which is
fast absorption.
Dolomite lime and or garden lime (same thing just called different)
which is slow absorption.
Sulfate of Potash, Magnesia which is medium absorption. Worm Castings,
which is slow absorption.
Crabshell which is slow absorption. Earth Juice Mircoblast, which is
fast acting. (a must buy!!
Has lots of 2ndary nutrients).
Now if you added to much chemical nutrients and or organics,( which is
hard to burn your plants
when using organics) You need to Flush the soil with plain water.
You need to use 2 times as
much water as the size of the pot, for example: If you have a 5 gallon
pot and need to flush
it, you need to use 10 gallons of water to rinse out the soil good enough
to get rid of excessive
nutrients.
What’s an air dome and why is it connected to a hose in the coco?
In an autopots setup there is an innovation called an air dome that blows air up through the soil. It acts to expand the soil and provide breathing space for the roots. Plants grow really well with these in the bottom of a pot.
thanks people there looking better just not growing at all still at 9 inches and been on veg for about 7 weeks mad never ever had this problem b4 any tips and i dont have air domes that my tube for my drippers haha (and i have from seed about 3 times never had this problem ment to be a big plant as well )
