4 Weeks no flowers?

Kyse Porter said:

My auto seeds germinated Feb 21. On March 28th none of them had flowered. I switched the lights to a 12/12 cycle in hopes of forcing them into flower. All but 3 have started to flower. My question is once they all start to flower should
I return them to the 20/4 cycle? What are the risks?

If your seeds are really autos they will flower regardless of the light cycle.
Where did you get them? (breeder/strain)

Delicious Seeds, Critical Neville Haze Auto.

" usually " around 30 days or so. Your autos will sex out first ( throw pistils ) , then transition. They will flower under ANY LIGHT SCHEDULE.

Now is the time to give it as much light as possible , its veg stage is preset and will go up to sexing , THEN it will start a big ass stretch. It will grow rapidly.

If for some reason .... AFTER say Day 40 and nothing is happening THEN DO A FLIP .
Autos are unpredictable .... Even seeds from same stock may show father traits or mother dominate traits. I grew 4 WW autos and 3 were same and one looked like a bush.

Keep feeding your veg nutes up to first week of flower ... This will " load " the plant with enough nitro to carry thru flowering when you switch to bloom nutes.
If you feed bloom nutes to early , plant will yellow up leaves fast looking for that nitro.

Autos are ridiculously easy .... Plug and play. Plant has a prewired life cycle and once they pop they dont stop.

The issue is that I have already switched the lights to the 12/12 to force flowering. What now?
