Auto flower is being a C****

[Passthatshit69]

Have an auto flower that is giving me problems. First off I planted this thing over 10 weeks ago , it showed preflowers over 2 weeks ago but ever since then its giving me problems. This plant had huge vigorous healthy growth during veg , then once it showed preflowers I started getting slight yellowing of the leaves , rust spots and purple stems and now it just wont flower.

I'm growing this plant organic using a 300 watt Led light , eco thrive supersoil and provide it with a compost tea every 2 weeks.

I have attached pictures and hope someone can help.

Tldr - auto flower over 10 weeks old , not flowering , rust spots and purple stems

70 days! those yellowing are old Have you tried 12/12 to see if it is a hoto?

I was thinking that it was a photo , but apparently it wouldn't show preflowers if it was

I thought that it might be , but apparently it wouldn't show preflowers if it was. Any idea what causes those spots in the 2nd picture?

I think a 5 or 6 week veg of a photo would show preflowers.

Damn I never knew that , I've never grown a photo. I guess it's my first time now.... Thanks for help

ph is my guess locking out uptake or something real hot like bat guano.

I didn't think I need to worry about pH in living soil , the last thing I wanted to be doing is worrying about pH

It sure looks as big as a 70 day old auto -buds. brown spots and all.
I'm not grown but 15 or so autos over the years just checking if they have got it right yet.
not being able the save a clone of the one you want to keep is the

Preflowers mean nothing. Just showing you ots a female.
You have a photoperiod plant there. Autos flip to flower Automatically in about 30ish days from seed. No auto is gonna veg 10 weeks..

To an extent with active microbe s but tap water of 8.5 or 4 should be buffered.

Autos are better off grown outside or in windows.
You'll get more from a photoperiod with a 3 week veg, and the buds will be that much better since they don't contain ruderalis that is 0% THC...

Not all autos are stable. You can still get wide varation of flower times and looks from seed. Some plants can come out semi auto. Just depends on how good or how much work the breeder did to lock in the trait as well as the type of genetics they have tried to make into a auto. Ive seen autos under 24 hour light flower for 18 weeks and just keep growing more new bud as the breeder probably needed to tip the scale and got abit more auto in the seeds. So it could still be auto, might just not be a great atempt at a auto seed, or might just be a photo. Only way to know if its photo for defo whith out messing with it too much is really is to take a cut and see if you can keep it in veg indefinatly. This goes with any seed, auto or photo, do your research and try to go to a breeder who knows what he is doing and makes good seed.
Probably a good idea to drop your light on hours down as it should get it going either way now.
