Leaves consistently turn yellow by week 5

[Gurtgurt]

I grow in organic soil using the popular Gaia green amendments. I grow similar to YouTube's "Canucks grow" and this site's "shaded's method."

I have a boogie brew filter for the water. I used to not pH, now I do, and the problem remains.

Here is my best guess: most guides use 5 gal pots and have you re-amend every 4 weeks. I use 3 gal pots, and this run have re-amended every 3 weeks. Add fertilizer plus ewc just like everybody says.

I water when the leaves droop, slowly, to runoff. Each plant gets ¾ gal every 3-4 days (est).

AND YET, every motherLOVING time this happens:

1. Wk 3 small leaves at base of branch die, all else good
2. Wk 4 single big leaves at the base of the branch may show deficiency but eventually yellow, all else good
3. Wk 4-5 suddenly most of the big leaves start to yellow
4. In a couple days, lots of big leaves yellow and die.
5. Week 6,7 I'm left with completely bare branches up to the bud.

The only green left is the small, clustered together sugar leaves around the bud. I'm thinking of all that photosynthesis I missed.

Why has this happened consistently for several runs? I'm doing synthetic nutes next this sucks ass.

Edit: so my assumption was they were running out of nutes too soon in a 3 gal pots, and by the time I amended it was too late for then to be absorbed. This run I am amending more frequently, but same problem as always!

Is it possible that the flowering is finished and the plant is done? I see some amber pistols in there. I will sometimes leave a plant (especially autoflowers) until they have the same kind of leaves you see on yours. Photo periods sometimes I do. It depends on the stage of the buds amd tricome colors.

If the flowers are mature and your tricomes are begining to amber, the plant may just be done. These surely aren't 5 weeks ild from seed to have flowered that much.

What are you holding for a light cycle?

How many weeks is that cultivar flower time? Looks like an auto.

Y'all are right. For these pictures, they were on week 7 day 1. I still expect the leaves to shed... The window may shift from run to run, but the progression of problems listed above seems to haunt me.

These are 4 different strains, one is a clone, all photoperiod.

I tend to grow sativa dominant strains. Maybe I suck with the 30x loupe. I always tell myself they could use more time. On the buds I see a lot of broken heads and not much amber, even after 9-10 weeks :(

Lights are 30 inches above at around 75 percent. This is the highest I've been able to run. So these pictures are the best run in recent times, but still leaves starting to fade

Honestly, these look pretty good. I think you've done well. Maybe some close up pics of the buds would help.

In nature the days get shorter and shorter during flower. I can make a photo period plant go to a cloudy white tricome color and make it stay that way for a month by turning my light intensity from 60% to 80% and holding 12 hours on time. But the pistols will brown, and the leaves will all fall off. I do a batch like that on purpose because it puts you to sleep. You get more cbdn and less thc.

Try a batch just like you've been doing, but at week 4, shorten your on time (assuming 12 hours on) 35 minutes each week until you get to 10 hours. I bet your tricomes change color much faster and the leaves will still be on it.

Buuuuutttt.. if your goal is maximum white tricomes, keep doing what your doin!
