A little help with a sick girl

Hi everyone. I’m new to the site and have been checking out many of the blogs and forums. I realize now there’s many things I haven’t done right but have had decent grows in spite of what I’ve been doing. I have grown mostly outside in the Northeast US, however I experienced a bad year last year with mold. So fearing the same situation this year I moved my plants into a recent indoor tent setup. 4x8x7. Plants were moved inside about 2 weeks ago. I have 3 plants (clones) and one is not doing very well. Multiple situations have caused issues this year with the grow. I started the plants in the ground in May. Once the leaves got on the trees it was apparent they would not get enough light so they were transplanted into 5 gallon buckets. So a pretty shaky start. Without getting into too much detail, they are currently in the tent with 2 Hi Grow LED 1000w LED full sprectum. After researching, it seems like a calcium deficiency. My 2 other plants are not experiencing these issues. The one that’s bad had a mix of MG soil and dirt from the area, the othe 2 are straight MG potting soil. I know not the best potting soil. I never really used nutrients for outdoor grow other than MG early on and had relatively good success. Clones were supposed to be 1 Sour Diesel and 2 blueberry/ lemon drop. Never heard of lemon drop strain. Who knows. Check out the pics. First one is supposed to be sour Diesel, second one BB/LD. Any info would be great in treating the sick girl. Thanks.

Are yhe leaves getting brown and crunchy?
The pictures get blurry as you blow tbem up a close up of the affected area would help also can fill a support ticket out ao we can get all the important info

Ill post one here for you

COPY/PASTE the below list into your forum post.
Answer these simple questions the best you can.
If you do not know, or do not use something; Just say so = NA

  • Strain; Type, Bag seed, or NA
  • Soil in pots, Hydroponic, or Coco?
  • System type?
  • PH of runoff or solution in reservoir?
  • What is strength of nutrient mix? EC, or TDS
  • Indoor or Outdoor
  • Light system, size?
  • Temps; Day, Night
  • Humidity; Day, Night
  • Ventilation system; Yes, No, Size
  • AC, Humidifier, De-humidifier,
  • Co2; Yes, No

If you can, upload a picture of your plant. It helps the diagnosis, if needed.

Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but short, to the point questions and facts will help us help you :slight_smile:

Top picture looks like nute burn or ph issue
What ppm you feeding at

What do you ise to read run off to get ph
Do you have a tds meter

Is the soil also MG that has time release nutrients?

? You don’t feed them?

Not yet. They were growing outside and hit them with some MG a few times. I recently move to a new place. Grew them in my garden at my old place before that was fertilized with horse manure and had good success without nutrients. Indoor is all new to me. They have been indoors for about 2-3 weeks but the one plant was showing these signs outside, just not as bad.d

No nutrients. I don’t have a TDS meter yet. On order. PH in has been 6.5-6.8. Buffering with lemon juice. It’s well water at about 7.5 out of the tap. Output is about the same. Regular MG potting soil. Like I said the other 2 plants have no signs of this.

If ‘MG’ is Miracle-Gro, that might be your problem. I think if you had success with it in the past that was an anomaly or you didn’t use much. It is a ‘time-released’ feeder, that tends to give your plant exactly what they don’t need at any particular time :wink:

However my other 2 plants look fine. This particular plant had some of the regular soil mix in with MG. The other 2 that are doing fine are straight MG.

You are showing at least one deficiency, or over-abundance, or a combination of a few o those. I’m a newbie too, so I can’t help with the specifics. I do know that one remedy for almost any problem is to flush. Another is Cal-mag. Not sure how well that will work with the slow-dissolving nutes in the MG.

@garrigan62 is the man on this stuff - if he’s on-line.

Looks like possible potassium issue to me


I’em here my friend. What’s up?

Manganese (Mn) Micronutrient and Immobile Element

Manganese Helps enzymes break down for chlorophyll and photosynthesis production,
as well as it works with plant enzymes to reduce nitrates before producing proteins.

Having plants that are deficient in manganese can turn the young leaves into
spotted (mottled) yellow and or brown areas on young leaves. Dead (Necrotic)
yellow spots form on top leaves, while the lower older leaves will or may have
gray specks and or spots. Symptoms can include yellowing of leaves while the
leaf veins can stay green. Can also produce a chequered effect. As the plant
gets newer growths the plant will seem to grow away from the problem, that’s
why the younger leaves may be unaffected. On the top of the leaves, brown spots
can appear. While the severe areas of the leaves turn brown and wither.
Parts Affected by a Manganese deficiency are: Young leaves.

Too much Manganese in the soil will cause an iron deficiency. The blotchy leaf
tissue is caused by not enough chlorophyll synthesis. Your plants will seem to
have very weak vigor caused by the excessive amount of manganese.

Problems with Manganese being locked out by PH troubles

Soil ph of over 6.5, High iron soils, Low nitrogen Soils, Dry weather
and compacted soil.


Manganese gets locked out of soil growing at ph levels of 2.0-5.0
Manganese is absorbed best in soil at a ph level of 5.5-6.5 (Wouldn’t recommend
having a soil ph of over 7.0 in soil) anything out of the ranges listed will
contribute to a Manganese Deficiency.

Hydro and Soil less Mediums

Manganese gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-4.5
Manganese is absorbed best in Hydro and Soil less Mediums at ph levels of 5.0-5.6
(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 manganese deficiency.

Solution to fixing a Manganese deficiency
Foliar feed with any chemical fertilizer containing Mn., or mix with water and water
your plants with it. Any Chemical/Organic nutrients that have Manganese in them will
fix a Manganese deficiency. (Only mixing at ½ strength when using chemical nutrients
or it will cause nutrient burn!) Other nutrients that have Manganese in them are:
Manganese chelate, Manganese carbonate, Manganese chloride, Manganese dioxide,
Manganese oxide, Manganese sulfate, which are all fast absorption. Garden Manure,
Greenssand are both good sources of manganese and are medium/ slow absorption.

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.

Thanks. I’ll do a flush and treat. I’ve only got about another 4 weeks or so to harvest. Plant is definitely stunted compared to my other 2. One has no sign of this issue the other just very slight.
