Typical disappointing auto flower results.
It is for this reason I will never grow auto flowers again.
Having your lights at 24/0 for weeks on end probably hasn't helped, all plants actually need a dark period every 24 hours to complete their photosynthetic cycle. Without the dark period, plants will have an incomplete metabolism, possibly leading to improper growth cycles.
18/6 is optimum, from day one until harvest with auto flowers, - 18 hours is about the maximum a cannabis plant can grow for in any 24 hour period.
The myth that cannabis can be healthy and grow normally without ever "sleeping" is one of the most disappointing pieces of misinformation in the cannabis world in my opinion.
I urge all non-believers to google photosynthetic cycle to find out why plants need sleep as a vital and integeral part of their existence.
Unfortunately, your plans of world domination will have to wait. Next time, go with superior photoperiod plants if you are after yield and predictable results.
Hope this helps in some way, Organoman.
