Flowering growth slowing, what would you supplement with?

Around wk 2 1/2-3 of flower now (I don't keep close track). Plants are totally healthy, just flower growth is slowing quite a lot.

Growing in roots/supersoil w/xtreme mycos. Using blumats, could if needed excavate small holes at drippers to add amendments, or use teas.

Not interested in commercial nutes. I have all the ingredients for super soil, plus some molasses, worm goodies and kelp around. Prefer not buying more stuff if possible.

Thinking some molasses and worm castings.

What would you do?

Your stretching is about over now. You should see more growth happening from the buds filling out. With super soil you shouldn't have to add anything at this time. You might have to top dress weeks down the road (if you didn't put enough super soil in the pot.)
Here is a post that I asked a week or so ago. Some times it is hard to get answers in the organic section( don't know why). Give a rep to Kountdown and Kratoas015 for taking time and there knowledge to help out.

Sorry forgot the post https://www.rollitup.org/organics/656470-my-tea-good-veg-flower.html#post9095898

Eh, I'll just go with worm goodies, molasses and kelp and call it good.

i'm in the same boat as you.

You might also try a banana peel tea in case your plant needs a little potassium for flowering...it's just like it sounds boil some banana peels (and some banana if you want) in water, let it cool, strain and water your plants with it. If it needed potassium then you'll see results within a few days.
