I have a plant that is not flowering and is supposed to be an autoflowering plant. My light cycle is 12 + 12 and the plant has been growing for 4 months now. Is there any way that this planet will ever start flowering? Has anyone else ever experienced this problem? The strain of the plant is Bruce Banner. Thank you EP

i have the same issue. great growth but no flowers after12 weeks of 18-6 light schedule in an octopot system. any thoughts? thanks in advance
I have posted for pictures the first picture is of the plant in question that I talked about. The second picture is of my nicest plant that I have not had trouble with and the third picture is of my grow area and the 4th picture is of my new starts. I use LED high intensity lights which I have had no problem growing in the past with. I bought a batch of seeds from ILGM and it was a bad batch of seeds they sent me. I got a hold of ILGM and explain to them what their seeds were doing because the seeds they sent me would not sprout. They sent me a new batch of seeds so I wonder if it's because of a bad batch of seeds they sent me. I use coco as my growing medium and the fertilizer I use is from Fox Farms. Thanks EP

You use LED light bulbs to grow with? There is no airflow to those pots nor coco. You have wrong lights
Before I started using the LED high intensity lights I was using CFL bulbs. I have attached pictures showing the type of lights that I am currently using which I use a mixture of two types of LED I also included in a picture my fertilizers and my venting system along with my air circulating oscillating fan. I've also included a picture of the type of CFL bulbs that I used when I first started and the area that I used to grow in is 4 ft by 4 ft by 4 ft. Thanks EP

The brown leaf tips that are curling up or down, along with the paler color on the outer edges of those leaves, are signs of nutrient burn on your larger plants in the pics. You may want to dial back the nutrient level a bit. If you are using the recommended amount according to the nutrient package, you can safely use 75% or 50% of that amount. They are in the business of selling nutrients, so they are going to tell you to use as much as possible!
Seedlings and vegetative plants need light in the 5000-7500k temperature range. For flowering, 2000-3000K light temperature is needed. GWE doesn't have a good explainer of light temperature/spectrum but here is one: https://www.growertoday.com/best-light-temperature-for-growing-plants/
Your plants are not getting the correct light spectrum. You are using "daylight" bulbs and one is labeled at 5000k. I can't see if the temperature on the other one. Your plants need some cooler light in the 2000-3000 Kelvin range. If the smaller bulb is in that range, then you probably don't have enough of them or they aren't close enough to the plant. You might have to change the ratio of bulbs or adjust the light distance. Flowering bulbs you could try: amazon.com/GE-Lighting-93101231-Reproductive-Flowering/dp/B07NNZXGMW/ and similar.
Or just upgrade to a few inexpensive LED panel lights. There are a ton of them available online and by the time you add up the cost of a bunch of individual bulbs and their fixture, it's cheaper to just get the LED panel. Lots of options, just set a max price on amazon to see the less costly options. Pay close attention to the true wattage, which is the actual power draw of the light. They like to list the wattage as "HPS Equivalent" such as a 150W LED panel that they claim is equal to 2000W HPS. Don't pay any attention to the thousands of watts in the listing. Compare PAR values (most listings have this) and the true wattage. A lot of the small ones will only cover a 2'x2' area for flowering. You'd need 4 of those for full coverage but I've seem them as cheap as 2/$40 so you could get complete 4'x4' coverage for $80.

That needs more airflow coco compacts when damp. Need some perlite stones to lighten the soil. For seedlings CFL grow lights are fine 54w grow lights for plants. They'll be happy for a few weeks but then they'll need something similar to sun, so full spectrum.
