Ok I will post pics when I'm home. Temperature in the room is 88 when the lights on about 70 when its off. The room isn't humid. I had a problem with some mold about a month ago but got rid of it in a day. Their in 1.6 gallon pots and are about two to three feet plants, extremely wide though. The plants are watered a third of a gallon of purified water anytime I can stick my finger in the pot and my second knockle isn't wet. The last time they had nutrients was right before flowering but when they began to droop I flushed them and they've just ben receiving water
O.K.... First things first...the small size of the containers (1.6 gallon) was a definite factor in the stunted growth.
Another major factor is your temps...88 degrees farenheit is too hot, sorry!
Plants exchange water vapor and gases thru pores called Stomates or Stomata. When it gets too hot these pores close up and the plant starts the slow march towards death.
Here is what happens when it gets too hot:
Temperatures
Plants have optimum growing conditions across the range of temperatures from 70°F to 85°F. Hot temperatures can injure and kill living plant systems. The thermal death threshold varies depending upon the duration of hot temperatures, the absolute highest temperature reached, tissue age, thermal mass, water content of tissue, and ability of the plant to make adjustments to temperature changes.
Internal changes within the plant as heat loading effects increase:
- Decrease in photosynthesis (Ps) and increase in respiration (Rs).
- Closing down of Ps (turn-over point for Ps and Rs = 95°F).
- Closed stomates stop CO2 capture and food production.
- Major slowing of transpiration (loss of heat dissipation, increase of internal temperature, and transportation / absorption problems).
- Increasing cell membrane leakage.
- Continued physical water loss and dehydration.
- Cell division and expansion inhibited, and growth regulation disrupted.
- Tree starvation through rapid use of food reserves, inefficient food use, increased photo-respiration, and inability to call on reserves when and where needed.
- Toxins generated (cell membrane releases and respiration problems) and deficiencies of elements and metabolites occur.
- Membrane integrity loss and protein breakdown.
- Local cell death, tissue lesions, and tissue death.
So basically:
-Larger pots are critical not only for proper growth but also cooling.
-Best temps for flower are not higher than 77 degrees if you can (75 ideal) a bit higher for properly CO2 enriched rooms.
-Proper amount of FRESH air from outside. Normal CO2 levels in outdoor air is approx 387 ppm average.
Good luck!
