Leaves curling after I added cal mag

Should I be concerned with this? It’s in a few spots.

Any thoughts?


Heat stress perhaps?


I thought that was possible as well, so raised the light a little. I appreciate your thoughts on this.


yeah what @SKORPION said. Heat most likely, but they will do that with excessive light too. They are not the same thing.

Please be as complete as possible. If soil please tell us WHAT soil. WHAT light etc. It’s all important.


Good to fill in the ticket but I agree they looked stressed by light or heat. The colors look good, but the leaves curling like that point to lights.

In my completely novice opinion anyways…

  • What strain, Seed bank, or bag seed -Girl Scout cookie from ilgm.

  • Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF -Aeroponic self built system.

  • Vessels: Pots, Grow beds, Buckets, Troths-net cups w/clay balls.

  • PH of Water, Solution, runoff (if Applicable)-between 5.6-5.9

  • PPM/TDS or EC of nutrient solution if applicable- about 600

  • Indoor or Outdoor- indoor

  • Light system -spider farmer 1000

  • Temps; Day, Night -day between71-82 night 68-72

  • Humidity; Day, Night -between 35-65

  • Ventilation system; Yes, No, Size- fans

  • AC, Humidifier, De-humidifier,- ac, humidifier both running

  • Co2; Yes, No-no

So temps do not get above 82, I did raise the light a little, any other thoughts?
@SKORPION @Zee @Cannabian @scylents

Put your hand above the plant, palm down, can you hold it for 30 seconds without your hand feeling burned?

I have tested the light for heat on my hand, there is none at the canopy. I have the spider farmer 1000, I believe 100 actual watts about 23 inches from the top of the canopy. @Zee

Wouldn’t be heat stress. How do they look since yesterday? How long from now till lights out for them?

A little better.
This is a little concerning though?

They do look better. That looks like that leaf got into a fight with another one and lost an eye. I had that happen because my fan was blowing into the girls, instead of over them.

I think the girls are adjusting to the calmag, I wouldn’t worry.

Dark green in Color, not dropping… :slight_smile:


@Zee thanks for your input, it is appreciated!
I was thinking that it may have been some wind damage, there 3 around different spots just like that around the plant as well. Sounds like you have pretty much the same though, thanks!
