Last chance....

Lol too much for sure. I should definitely stop smoking before posting, i end up mixing things up since it's a forum.
Roots slow down major once the buds look to grow significantly, sure they don't completely come to a standstill.
Watering the outside perimeter only when shes filling into the pot, making the roots even more vigorous as they stretch for water, and within a few minutes you can see the water soaking up into the middle from the roots. The plant receives plenty of oxygen and you avoid root rot that can take days to remedy. My dry conditions super easy to fix, and its usually only the top inch that gets dry, the micro biome remains safe inside.
As for the numbers, watering 15-20% water ratio to soil is easy enough, without complicating it too much as i change pot sizes all the time.

Oh damn my typo, i meant 5 Litres, not gallons.
Damn US conversion.
The roots would have done the major growth in veg up to a little after the flip. Then it slows down major in favour of bud production.

Totally wrong. The roots may slow in growth but keep growing until the plant is dead. I've transplanted mid-flower a few times and the new medium is full of roots to the bottom when I finish the plant off. I also cut the bottom off the rootball every time I repot so the pot fills with fine feeder roots instead of long strings of roots on the bottom at the end.

Water to saturation each time the pots feel light. Partial waterings are not the way to go.

First of all, thanks for your reply.

I did a flush on Friday 23.9 with 30L of water PH 6.8, at the end of the flush I didn't use fertilizer because I didn't know I needed it and I was afraid of making even bigger shit. Can you please help me how to proceed since I didn't fertilize after the flush . And am I right when I suspect nitrogen poisoning?

O yeah, i dont use calmag.

Basically once you've flushed you just do the last bit with half strength nutes so the plant has food right away. Basically resetting the balance in the pots to correct imbalances.

A full flush when using something like soilless medium and hydro nutes will remove almost all the nutrients in the pots. If it's an organic medium then it will just reduce the level of nutes which will replenish as the bio-herd breaks down more organics into the food plants need.

Partial flushes are just to knock down the nute levels when you notice a bit of nute burn showing up on the leaves. About half the volume of the pot is enough to correct something like that.

When I'm growing in ProMix HP using hydro nutes I would feed once then just water the next time but was getting into the habit of feeding half as much every time I watered and saw better growth that way. Also not letting the pots get really dry seemed to promote faster growth as well.

As I only use RO or distilled water for my indoor plants I do use a little CalMag but only about 1/4 as much as it says on the bottles. Now that I'm using all sorts of organics instead of AN 3-part I don't worry about the CalMag at all.

Next experiment is to put an airstone in the bottom of the pots to feed air in there once in a while and see how that affects growth. Another little side-by-side project to keep things interesting.
