I am having a hard time getting a sense of the aut...

Hi! Autos typically start flowering in week 4-5. I've found the manufacturers estimates on seed to harvest to be pretty accurate (across 5 auto strains). I have seen instances of late flowering starting week 5/6 as a result of stunted growth due to early mistakes (overwatering/incorrect ph and bad grow conditions eg too little light or too cold). In the case of stunting it's usually good if it starts flowering later because you then get more time to recover and get still get decent yield.(my sour diesel plants from virgin sour widow grow us good example) Another possibility is that you received photo period plants instead of autos. In this case it might help to switch to 12/12 light cycle to see if that triggers flower. Your plants dont look stunted so may be possible here. Another way to eliminate this scenario is if you start seeing flower whilst under 18hr schedule then it must be auto. Good luck with your grow!

Hello there! I grew tangerine dream and it was done around 85 days from seed. Hope this helps. Happy Growing!
