Not Flowering after 11wks

Please advise. I have a Hulk smash and Biscotti at the moment(both Auto's). They are in a 80x80x210 with a new spider farm light. Running on 18/6. The Hulk is long and spindly (90cm) and the Biscotti9(60cm) Anyway. These are now into the 11th week and normally under a 400hps I know they would be well in flower. Do I need another light? I moved from the HPS to the Spider Farmer one because of the reviews, heat etc. Thanks in advance.

It isn't the brand/type of light preventing them from flowering, but the schedule. Try switching to 12/12. Your autos are not autoing if it's really week 11.

Thank you. They started on the 20/01 and have been 18/6. I thought about 12/12 but all I read was leave any auto in 18/6. I put them in 24hr bark yesterday to try and induce flower, however I will switch to 12/12. Thank you so much for a speedy reply.

It seems like you either got a mixed up pack of seeds, or wherever they came from they hadn't quite bred them to be consistently autos. Generally you should give autos 18/6 or more, but when this happens for more than 6 or so weeks it is a photoperiod, and changing the schedule to 12/12 will kick them into gear. They will probably be bigger than you were expecting, so make sure to get acquainted with supercropping. :]

Thank you. I have moved to smaller tent, different lighting and just worried re the time.. They look as if they are going to flower. My issue is I have two seedlings. A week old. Will 12/12 stunt these? I normally have the seedlings in for rotation if that makes sense. Or should the seedlings be 12/12 from the onset. Sorry I am new and clearly with a small tent/lighting is away from HPS lighting

Seedlings run 12/12 will be a smaller yield, yes. it shouldn't stunt them causing any health issues though.
