New Grower Finally after 5 year of waiting, decided it's time for a new Grow.

[Don't Fear the Reefer]

Well I checked this morning and the yellowing leaves have yellowed more.
All the leaves growing inward are dark green and the tops and older fan leaves are yellowing.
I'll get a picture or two up later, when lights come back on.

You can most certainly over feed in organics.. I've have done and still do it

Also IMPO and from what I've seen a few other folks say it is almost impossible to overwater with fabric pots once the plant is established 3l isn't that much for a plant like that most of mine when I was using grow bags were drinking a 5 gallon pot dry in a day 2 at most during flower.. So I am wondering about underwatering especially since you mention she's gone droopy. In organics if the soil is that dry then the soil microbial life has taken a hit or possibly died off.. Just spit balling here I honestly think she looks really good for her age most of mine start "fading" around that point especially those lower leaves.. You know if you pluck them dying leaves off the problem is gone out of sight out of mind

I think my watering technique may have something to do with it.
I think I'll bottom water a bit and top water a bit and see how I get on.

It all seemed to start going wrong when I introduced the Bio Pk flowering booster, but it may just be coincidence.

I’ve ph tested my tap water twice previously and both times it’s been 6.2 & 6.1 so unless I’m using nutrients I don’t buffer.

I can go online and get the pH results direct from the water company supplying my area..I take that as a general indicator around 7+ and so have to add a splash of lemon juice to get in the range, only the best for my girls

Changed my mind, here are some pictures.

What if the coincidence is more than coincidence?
I would be tempted to flush with plain water for a week, one really good soak, 3-5ltrs of runoff, drain well and leave for 3-4 days, same again, if necessary... and see what happens.
At worse the old fans keep dying, at best you fix the issue in a week and can relax again.

This will also allay any concerns that you are under watering.

if the leafs keep dying opt for a week of drying, min watering 1.5ltr every 3days or only when the plant says its thirsty.

in two weeks you keep losing fans or you fix the issue.

The buds look really nice though, so there is that.

Oh yeah, i forgot to say "after the flush remember to give her a feed of normal full range nutes including nitrogen"

Could very well be a Calcium deficiency as some plants demand a touch more during mid bloom.

Thanks mate, the Bio PK has some calcium in it. Not seeing any spots either, do they not always show?

Not always.

Not always.

I'm at a loss then.
I always seem to get problems in flower no matter what I do.

maybe next grow you dont change anything when flowering starts, dont change the feed, dont change the water, dont change your attitude to the plant, just carry on doing what worked earlier and see how it goes, mark that down on your action list for the next grow

In the "good ol' days" we used tomato nutes from start to finish, and it worked pretty good as far as I remember, I still use tomato nutes for all my other plants on the balcony and in the house, old habits die hard.

I honestly think your making this a bigger problem then it is.. That plant looks great and most all of us have issues come flower time IMO a lot of time it is related to N don’t forget too much will lock out potassium and calcium.. Plus once a plants gets into flower it requires less nitrogen and one common miss conception is that the plant will just pick and choose what it wants. That is true is some cases but not with nitrogen the plant will still keep picking it and storing it whether it needs it or not.. Most of my issue have gotten better by cutting some N out come flower.

Also something to remember not sure if it was mentioned in here but keep in mind we’re not smoking the leaves the buds are what matters..

I am standing by my theory that plant is just starting it fading process by striping the nutes from those leaves and discarding them
