These are three cc4 autoflower plants that as of that date in the pics Dec 5th they are 180 days old with no sings of flowering can anyone tell my why this might be happening they are in a grow room 4×6 that is keep at around 75 while the light is on (12 ×12 cycle) and drops to around 65 in the dark 50 to 65 % humidity
Agree with what light. No matter what it is it is not close enough IMO because I can’t see it in the picture. There is a lot of room between the top of picture and the canopy.
Light is a little low for that many plants. Not so low to cause them not to flower. Especially if on a 12/12 light schedule.
How long on the 12/12 schedule.
If I’m real honest I would say start over.
Maybe change schedule to 8 on 16 off make sure room is completely dark at lights off. If nothing happens in a couple weeks definitely start over. JMO
75-80 temp promotes stronger growth. Cooler temps at the end will promote color change. A good spot for me is right in that window up to 85. I would get the temp up and see what happens. 3 months 12/12 tells me they are not maturing. Male or female. Just a possible reason.
Update on the autos that won't flower they are getting a red tint like it would if it were getting close to harvest but still no buds , the other plants are autos I planted about 8 weeks ago under the same conditions
