Is this starting to flower

Thanks so much....yes I am seeing more of the white pistols coming through 😅.....will add updated pics soon.

Yeah buddy just re-read your at 90 days then it's definitely a photoperiod. keep it 12/12 right through it will kick out more pistols everyday.

I see a few pistols at the top buddy so I would say yes. I taught with autos you didn't need 12 hours dark? I think 18/6 is what you should be doing buddy autos flower regardless not like photoperiod.

Since they have not started flowering yet should I give them nutrients again. They have just had water thinking they were going to flower 2 weeks ago. I was giving them florabloom and calmag

Not yet mate give it a bit longer. Flowering is little white hairs coming out from corners and tips. Look at my blue dream clone diary, clones are taken in early flower before the switch so mine has white hairs on it. If it's an auto I always do mine at 18/6 and don't swap to 12/12 but if the breeder messed up and gave you a photo seed it will flower under 12/12. You should only swap to 12/12 if your sure it's not flowering and you want to try force it to flower like your already doing.

no offense at all...need all the advice i can get I am so lost right now what I should be doing. These are on week 14 so someone told me they were not auto's and switch the lights to 12/12 which I did 5 days ago. But I also stopped all my nuts they have just had tap water past 2 weeks

I don't believe you are quite there yet. They should start flowering sometime around week 5 or 6. Just some advice: autos don't need a 12/12 cycle to flower and I don't think changing the light cycle will induce flower. Sometimes the breeder hasn't gone enough generations deep and you'll get autos that are actually photos, but I wouldn't work under that assumption until 7-8 weeks without flowering. I keep mine on a constant 18/6 and they are big and beautiful right now. Good luck!

Not seeing flower but you should get it straightened out before it does start to flower. Check your runoff ph and ec, get everything straightened out or you will have some real problems once you do start flowering. Not trying to be mean. Just my opinion. Cheers friend
