leaves yellowing in flower, but too early?

I know leaves are supposed to yellow off and die during flowering, but these have only been in 12/12 for five weeks. They were pre-flowering for quite a while before that though, I planted these seeds in mid-August. Is there a problem or do you think they're just finishing early? 4 or 5 fan leaves have already fallen off one plant. I've just been giving them guano tea (1-10-.02) and molasses and was planning to just use water for the rest of their lives after I give them one last tea today. How much longer do you think they'll take?

Pretty buds, what kind are they?

I believe that this happens in flowering due to nitrogen deficiency. It looks fine to me. If you do not want this to happen, you can give it a nice dose of veg nutes before you flip to 12/12, ( will control the 12/12 stretch as well) and another dose of veg nutes at week 4.

i think it's super silver haze and blackberry kush crossed with grape ape? i'm not really sure how he came up with the seeds but he calls it silver black ape.

yeah if that's the case that it's just sucking nitrogen out of the fan leaves until they die it seems to mean it's basically flushing itself so i'm totally ok with that as long as it doesn't hurt it. less work for me.

Why just water now, you are entering the fattening stage. Ya need a good dose of PK 13/14 and keep the nutes going, sit back and watch them swell.

yeah i figured i would play it by ear and maybe give them another dose, i've been doing them every two weeks but i added guano to the soil, too.

also i was gonna keep using molasses, i phrased that wrong

i'm realizing that this might have something to do with not enough potassium since the guano i've been using doesn't have much of any. i think i'm going to give it some half strength MG tomato fertilizer with the guano tomorrow to perk her up.
