Amenisa haze coco grow

Amnesia haze in coco canna… ph at 6.0 ppm is at 600-800ppm in 3 gallons of water. Using vitalink a and b with some camag, bioplus roots,silicon to bring the pH up. Noticed this black smudge on a lower leave and it’s getting bigger. Help?

I’ve just transplanted into 15 litre pots…do I need to water straight away ?

Ya you should have given them water give them some ASAP OK


How much should. I feed them after transplanting ? Any idea on the black Mark on the leaf Any1 (

The black smudge has gotten worse over night. Tried flushing with 6.0 water used around 3 litres. See how it is over night, any help appreciated :persevere:

Gave all babies a good flush with water at 6.1 with poms at 420. Checked the drain of the next day and the ppms where high 600s. Gave each plant another 10 litres of ph’d waters again. Still see signs of what I think is to be phosphorus??? Will see how they are later.

Strain; Type, Bag seed, or NA – amenisa haze seed

Soil in pots, Hydroponic, or Coco? Pure coco canna +

System type?

PH of runoff or solution in reservoir? 12 litre bucket with ph around 6.0-6.3

What is strength of nutrient mix? EC, or TDS 450-600


Light system, size? 600w hps

Temps; Day, Night
Day 25-30c night 20-25c
Humidity; Day, Night
36-45 40-60
Ventilation system; Yes, No, Size
6inch carbon and fan
AC, Humidifier, De-humidifier,
Co2; Yes, No

Still having trouble fighting of the problem . Gave them small dose of vitalink a and b for 4 days . Still no signs of improvement. The black marks seems to have slowed down but is still spreading .

Today’s feed I’ve gave just water and calmag to see how they react over next few days

Any1 help me out here please ?

In coco soilless medium you must add Calmag either every watering at 2.5 ml to a gallon , are every other watering at .5 ml a gallon , hope this helps !!!

I’ve used 3mil to 12litres . Then I’d top back the water up so it’s diluted on its next feed. Showing slow signs of improvement. Going to water them 2 days time with 5mil of calmag to 12litres of water.

Think I’m chasing a lost cause tbf!
Baby 1 recently topped.

Baby 2 the sickest one

Baby 3 the biggest 1

They will recover , but always add iron to coco , due to it be a neutral soilless medium .

This is what I think it is . Sorry I’m late but I don’t think its Zinic

This pic. Is why I think its a Nitrogen Deficiency

less Mediums
Nitrogen gets locked out of Hydro, Soil less mediums at the levels of 4.5-5.0.
Nitrogen has the best absorption rate at a ph of 5.5 to 8.0
(Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range to have Nitrogen is: 5.0-7.0. Anything out of that range will contribute to a nitrogen def.

Solution to fixing a Nitrogen deficiency

Avoid excessive ammonium nitrogen, which can interfere with other nutrients. Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.
A goof solid N-P-K ratio will fix any nitrogen deficiency. Any chemical or organic fertilizers that have Nitrogen in them will fix a nitrogen deficiency., Peters all purpose plant food 20-20-20 is good, Miracle grow All purpose plant food, Miracle grow Tomato plant food, (Only mixing at ½ strength when using chemical nutrients, or it will cause nutrient burn!) as well and blood meal! If you need to give your plants a quick solution to nitrogen and you want to use blood meal, I suggest making it into a tea for faster use, where blood meal is slow acting, but when made into a tea it works quicker! Other sources of nitrogen are dried blood, Cotton seed meal which is slow acting, Insect eating bat guano which is fast acting. Bone meal which is a gradual absorption when not made into a tea.( also excellent source of phosphorus). Fish Meal Or Fish Emulsion is a good source of nitrogen and is medium acting. Worm castings, which is gradual absorption. Seabird guano, All purpose Millennia Seabird guano, Orginal Seabird guano All Purpose, Crabshell ,which is slow absorption. Fox Farm Grow Big, which is fast acting. ( can bring down your ph as well)

So adding anyone of these above should fix up your nitrogen deficiency! Nitrogen deficient plants usually recover in about a week, affected leaves will not recover.

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. Soluble nitrogen (especially nitrate) is the form that’s the most quickly available to the roots, while insoluble N (like urea) first needs to be broken down by microbes in the soil before the roots can absorb it.

Note: Blood Meal, Dried Blood, Guanos, Kelp Meal, Cotton Seed Meal, Peat Moss, Sulfur and fish meal are all acidic and can bring your ph down, so if you add these please monitor your ph when using those.

Note: Bone Meal, Rock Phosphate, Wood Ashes pretty much all ashes, Shellfish Compost and Crab Meal are all alkaline and can make your ph go up, so if you add any of these please monitor your ph.

Here are 3 pics of what a nitrogen def looks like… the first one is a nitrogen deficiency in vegging. the 2nd picture is nitrogen def in flowering; THis is completely normal for mid to late flowering; as you would want your plant to naturally yellow at the end. DO NOT add nitrogen supplement to fix the problem; just let the plant yellow as cannabis does towards the end of flowering. The last picture is one that is caused by TO MUCH Nitrogen.p

Thanks for your help @garrigan62 I’ve fed them with some calmag 5ml into 2gallons of water along with 3ml of a and b for some extra nitrogen. All 3 plants had 1.2 litres of tha mixture. Fed again today same as the last feed. Plants are really slow growing…

That’s great to here :joy:. Anytime. That you feel that you need help just ask…ok
