An update on my 4B “Aaron’s winner” Ogreberry F4.
Today they are 22 days old from sprout, growth rates are right on track, nice early branching structure so far, humidity was high this last week, they might have slowed down a bit.
Overall easy growing, no issues, next week on to full strength nutrients. It does appear one is small and runty, since they are testers I will keep it growing for research, I usually cull smaller plants from the garden. The P Punch next to it is half its age for reference of growth.

A quick comment on early maturity, in my experience stress factors, environmental and nutrition can impact when autos or photos show sex, although I wouldn’t want it to show to early in my autos, I have not found it correlates to early flowering/maturity or small or stunted plants. I feel that “mini” effect is a genetic variation in autos that pops up now and then, out of 5 seeds one will have that stunted rudialis trait just about always. It’s the beautiful nature of autoflowers.
Another thing about using nutrients, I would consider keeping them on veg nutrients until the flowers are the size of a cotton ball or larger, I do not switch to flower nutrients too early I wait until they are well into flower, in my experience autos require more nitrogen during flower than photos, if I introduce flower nutrients early or change the levels of P and K they will show preflower, and grow on the smaller size, I would like preflower to happen late as possible due to the short life of the plant. Unfortunately we are never really in control of how the plant will grow, we can manipulate all we want, nature has its own rules.
This is my opinion that works for my particular style, I’m not a pro, many grow way better and know how, more than me. Just my experience so far.
