Pictures of marijuana symptoms caused by over-watering, too much heat, and small containers


by Nebula Haze

Here's a series of pictures of a couple marijuana clones I had a few years ago.

I was experimenting with growing an entire plant from clone to harvest in a solo cup, which is why you can see flowering plants in such small containers. Each of these were flowered as soon as the clones took root. This technique is often called "Flowering from seed" or "12-12 from seed" and just means that you force the plant to start flowering at a very young age. I wanted to see how small I could get flowering plants.

Each clone was give the exact same nutrients, conditions, etc. They were green and healthy when I left for a 3-day trip.

Situation: I was leaving for 3 days, and these flowering marijuana clones needed to be watered almost daily since their containers were so small.

In an attempt to give them enough water to last the trip, I over watered them before I left.

When I got back, the plants looked like they had practically died!

Look at how different all of the symptoms were with each of these plants, when the problem was actually the same for all of them:

Same Underlying Problem For Each of These Clones

  • Overwatered
  • Kept in a grow room that was way too hot (it got up over 100 degrees while I was out of town, and they were kept in these temps for 2-3 days)
  • Too small container for their roots (with bigger root mass, marijuana plants are much more resilient to problems)

(remember, these clones were ALL green and healthy before I left, so I feel certain these problems were all caused by the reasons stated above)

 

Resulting Symptoms Varied Greatly

Clone 1: leaves yellowing and curling up like elf feet, tip burn

Marijuana clone one - leaves turning up like elf shoes

Clone 2: curling, rusty brown edges and brown spots

Marijuana clone 2 - rusty outer edges of the leaves and brown spots

Marijuana clone 2 - another view of rusty outer edges of the leaves and brown spots

Clone 3: Gets a different type of rusty brown spots

Marijuana clone 3 - A different type of rusty brown spots appeared on this plant

Clone 4: Lime color and curling upwards towards the top of the plant, and yet another type of rusty brown spots and yellowing / curling towards the bottom (looks like a nitrogen deficiency on bottom)

Marijuana clone 4 - Yet another type of rusty brown spots appeared on this plant, with yellowing of the leaves and curling up

Marijuana clone 4 - Yet another type of rusty brown spots appeared on this plant, with yellowing of the leaves and curling up

Clone 5: brown spots on top, taco leaves, browning, curling of lower leaves, like a phosphorus deficiency (this is the only clone the appears to have what looked like a phosphorus deficieny in the lower leaves)

Marijuana clone 5 - Taco leaves, brown edges and brown spots

Marijuana clone 5 - Taco leaves, brown edges and brown spots

Marijuana clone 5 - Close up on the brown spots on the lower leaves, they look like a phosphorus deficiency, yet this is the only clone showing this symptom

Clone 6: rusty outer edges, brown spotting

Marijuana clone 6 - Taco leaves, brown edges and brown spots

Marijuana clone 6 - Taco leaves, brown edges and brown spots

Marijuana clone 6 - Close-up of the brown spotting

Marijuana clone 6 - Close-up of the brown spotting on lower leaves

Marijuana clone 6 - Close-up of the brown spotting and yellowing on lower leaves

 

The truth is, when the marijuana plant's roots are not happy, and when plants get too hot, they freak out!

Often the symptoms may vary quite a bit, even if you have the same underlying problem.

I fixed the problem (controlled heat, and proper watering practices). Symptoms stopped getting worse. Nearly all of them pulled through and made it to harvest.
