sorry the pics are from a cell phone and i took them at about 10 pm

What are some causes of slow plant growth?

Overwatering
Soil moisture that is not absorbed rapidly turns stagnant; the plant quickly uses up any oxygen within the water, then is unable to respire further, resulting in moisture low in o2. Pythium thrives in low-oxygen (anaerobic) conditions.

In short, overwatering will slowly suffocate your roots, preventing sufficient oxygen uptake by the roots, and ultimately causing root rot.

Soil with high bark content
This can cause a “bonsai” effect. The roots will not be able to grow through the bark, preferring to grow around the chunks of bark. This slows down root growth and most obviously plant growth. Ive encounter this recently; once transplanted into proper soil, they have shown remarkable recovery.

[Editor's note: bark is quite acidic, may may afect soil water pH]

Light deprivation
Although your plant may be receiving light, particular strains may require higher light levels than others. A recommended light level for full bud development is 50 watts/m2. Full sunlight is 100,000 lumens max.

Low nutrient strength
The plant is unable to acquire the necessary amounts of nutrients to sustain high growth rates. Large and mature plants can take higher nutrient strengths.

Nutrient strength is also related to the light intensity; plants under fluorescent lights usually require a lower nutrient concentration than under HIDs.

Nutrient lockup
Adding too much of a nutrient (ex. Magnesium) can “lockup” one or more nutrients, rendering them chemically unavailable to the plant. Nutrient lockup can occur at extreme pH ranges (ie. under 5.0, over 7.0).

by Ranger2000:

Light spectrum
Light that does not contain enough red spectrum (too much blue)
Light spectrum can have a dramatic effect on plant growth, with different ligh frequencies affecting different photosynthetic processes within the leaf. Selecting a blue spectrum in a vegetative growth phase is preferred, with red spectrum in flowering.

pH
pH is too high or too low (ie. acidic soil. The plants come out as mutants).
Plants are unable to absorb nutrients, or in adequate quantities within certain pH ranges. Optimum pH varies with each medium. Hydroponics and aeroponics: 5.6-5.8. Soilless: 6.0-6.3 Soil: 6.5-7.0.

Many soilless mixtures can be fairly acidic, due to their high % bark content.

Low temperatures
Plant metabolism will decrease at low temperatures. Chemical reactions within the plant will take longer. Optimum plant growth often requires close temperature regulation; daytime temperatures between 25C and 30C are preferred. Differences in daytime and nighttime temps should not be dramatic, as this difference may shock the plant.

by 10K:

Low soil / medium temp
Evaporation from a medium (i.e. peat pots) tends to chill the medium quite a bit due to the evaporative cooling effect. As the peat pot warms, it draws moisture outward, the evap effect cools the peat (like sweating). New growers often make the mistake of adding excessive amounts of water, resulting in cold soil, poor root formation and slowed growth

Well bro from what I have learned here you want something that is high in nitrogen, you know the three little numbers on fertilizer bottles? Well the first number is Nitrogen, I use Fox Farms Grow Big for my Veg/Grow cycle it is 6-4-4 when your ready to flower I would suggest something more along the lines of 2-8-4 like in Tiger Bloom, or Fox Farms Big Bloom is .01-0.3-0.7 still has a bit of nitrogen but higher Phosphate and Potash/Potassium. Just remember the 3 numbers are Nitrogen-Phosphate-Potash/Potassium. Higher Nitrogen for Veg/Grow then switch to lower Nitrogen and higher Phosphate-Potash/Potassium for Flowering/Budding. All that information I got from right here, reading Widow Makers step by step instructions, asking different members etc etc... Trust me man, I had NOOOOO clue whatsoever as how to grow until these fine folks showed me the light (no pun intended) lol Wish you the best of luck and go ahead and smoke bro, we'll grow more!!! Yeeeeeehaaaaaa!!!!

thanks for all the info guys i suspect its a combination of overwatering from rain and low temps, this tx weather is crazy one week itll be 95 the next we get a cold front taking it back down to 60
