I wouldn't doubt that spraying late into flowering is helping to keep those buds so undersized. Using soap sprays, which are what I use, after week 2 is sure to be tasted in the final product. You should follow up any soap spray in flower with a plain water rinse off the next day. No matter what you spray do it without the grow lights on them and teh fan off to give the soap time to kill the bugs before it dries up. I add 10ml/L of cheap canola oil to my Safer's End All concentrate for better killing power. A lot of the commercial sprays use it instead of neem oil and it's just as effective.
Stop spraying in flower.
Or if you have to spray because of bugs use something like citric acid or a citric acid based product that will kill the bugs in one maybe 2 sprays and call it a day.
Oh man! She needs some help if you want to make it to harvest with anything worth smoking! What are the details?

If you have some bloom food high in potassium that will help put some weight on the buds and good old epsom salts will supply much needed magnesium and sulphur for late stage flowering. A dash of CalMag won't hurt either.
Good luck and a Merry Xmas to you and yours!

I did about 50 DWC grows since '01 but have been swinging into organics more.

What are you using for water? RO or distilled only for my plants. We have horrible tap water from a dugout on my property. 400+ppm and pH8+.
I like AN for hydro nutes. Never having to screw around with pH is a blessing.
I'm not seeing any nice white pistils on the buds you show. That's either they've been fried from the sprays you've been doing or the plant is done with producing new flowers.
A good portion of the trichs look cloudy as well. No pics of the lower parts to see the dying leaves? I see some nute burn on that first pic so wondering if it's not some toxic salts buildup affecting lower growth. Leaves will go yellow/brown all over and turn thick and crispy id it is. Fading to yellow all over and being soft and limp is the normal demise of lower leaves later in flowering.
Any idea what your nute strength is either EC or ppm?
Don’t use advanced nutrients
Flushing some water thru reduces the salts in pots but for a hydro setup you need to reduce the EC/ppm a lot so the plants are forced to steal nutrients from the older leaves and to use nutes stored all over to feed the buds. Can just take out a portion of your nutes and top it back up with water. RO or distilled is what I use all the time. This late in flower some Epsom Salts and potassium help to grow the buds and add to the resin. Most people don't have just K tho. I do but I'm not most people.
N and P are easily scavenged from other leaves and put where the plant needs the. K is as well but the plants like more K late in flower. No N if possible.
I assume you have done your due diligence and researched the subject in an unbiased manner to so confidently make such a statement.
You don't want to be putting something like a banana tea in your tank man. Bound to cause problems and the amount of K you'll get is not much. There's up to 4X as much K in a baked potato than there is in a banana but I don't recommend you make a tea out of that either.
What is the ideal EC in this phase, week 5 of flower?You don't want to be putting something like a banana tea in your tank man. Bound to cause problems and the amount of K you'll get is not much.

If nothing else I'd go to a health food store and get some potassium citrate 99mg, crush up a few tabs and stir that in. The citrate form is water soluble but there will be some sediment from the filler used to bulk up the tablets. Capsules would be OK as you can pull them apart and dump out already powdered stuff. No gel caps tho I doubt they make that in gels. I use a mortar and pestle to grind up stuff like that. Vit. B-1, Zn, Sn, ascorbic acid, (Vit.C), and a little citric acid.
I have a bag of potassium chloride plant food but bought a bottle of Earth Juice Meta-K to use instead to be a little more organic in my grows. Still going to use Big Bud a week before the flip and until the end of week 5 but just the K and a couple others like Epsom after that.
That depends on things like strain, a hungry indica can usually handle way more than a sativa. RH, lower RH use lower EC to prevent burn and toxic salts buildup.
