22.09.22/D42 - 6 weeks since germ and all are now in flower/preflower. Just gave NL2 some water with zym, pH 6,4, 43 ppm. Runoff : 390 ppm, so she ate about 1340 ppm since last feed. Will give her a new feed right away, as she will need more as she just entered pre-flower.
NL2 : 1510, 6.3 , 5l
Run : 1700, 6.3 , 2.7l.
Found mould in the soil, read that mychorizza might cause this
Got a heads up that i might feed them too heavy, and i was.. So i watered those who had more then 1000 ppm in the runoff.
NL2 run: 644, 6.3
NL3 run: 854, 6.3
WW2 run: 766, 6.3
WW3 run: 646, 6.9 ( gave a 6.5 ph water) .
23.09.22/D43 - Upped the light from 25-30 DLI over canopy tops, and removed dead leaves.
Water WW1 with pure zym: ppm 38, ph 6.1, 6l
Run: 751, 6.3, 2,3l
24.09.22/D44 - Hang up 2 pc fans for bottom air flow and removed dead leaves.
25.09.22/D45 - I made room for a 60x60x170 tent, and moved NL2 to the new tent, crossing fingers for a heavy harvest on her:) watering
NL2 : 38, 6.2, 5l
Run: 620, 6.4 , 1.8l
NL3 : 38, 6.4, 4.5l
Run: 400, 6.5 , 1.7l
NL2 : trying to bend her canopy towards the walls, to allow more light to lower shoots. Her DLI is 25-27 above canopy tops.
26.09.22/D46 - Trimmed 4-5 leaves that were blocking 2+ nodes, and tied 3 branches down/out on NL2.
Water
WW2: 36, 6.3, 5L / Run: 484 , 6.6 , 1.3l
NL1: ———"——— / Run: 566 , 6.4 , 1.2l
Watered down WW1 and WW3 with water. WW1 350 ppm and WW3 250 ppm. Gave them a new bloom after feed, listed in diary.
WW1: 695, 6.2, 5l / Run: 880, 6.2
WW3: 965, 6.2, 6l / Run: 752, 6.2
27.09.22/D47 - Water
NL3 : 700, 6.5, 6l / Run : 891, 6.4, 2.3l
NL2 : 700, 6.2, 5l / Run: 1080, 6.2
Supper cropped 2 shoots on NL2
28.09.22/D48 - Forgot to tune up the light in a couple of days, i raised it to 35-40 over canopy tops as they are all well into flower now. And the NL3 gets 20-30 in the corner.

High,
So when you water with runoff you are probably measuring the runoff for ppm right?
This is not the right way to do it because you will measure the build up salts and nutritions that RUN OFF the soil. That is why you water till runoff because you want the build up salts and nutrients out of your pot. And replace them by new fresh nutrients.
When you want to measure the pH or ppm from your soil just follow these steps:
1. Place soil sample about ¾ full in sample jar and add distilled water to cover soil.
2. Cap the jar and shake the soil vigorously a few times.
3. Let mixture stand 10 minutes to dissolve the salts in the soil.
4. Place the pH or ppm tester into the wet soil slurry.
5. Measure pH or ppm and record measurement.
Happy Growing! 😋

Seems like i got mould in the top later of soil on my 1 plant (WW2).
Beneficial fungus from mychorizza or harmfull? How do i tell the difference?

That's called mycelium bro. Its beneficial. It'll go after a few weeks. The plant will eat it up, as it decays it gives your plant a great boost in many areas. Fungus is generally your friend, unless you see it on your plant. You are growing in soil. You have a good thing going buddy.
Now, some of it might go green, and look like mold. Even more so if you use any synthetic nutrients like a calmag. Try not to though. (As cal/mag in an organic grow is not good, especially with fungus. I can think of the name, but I know it'll cause issues. So if you can get an organic cal powder or just an organic cal and epsom salt. (If you have water above 170ppm you won't need calmag) but a dash of 250ppm Epsom salt never hurts during late flowering..
Good luck pal.

if referring to picture 14 / 16 at the top of the plant, i'd wager it's light stress. but, those are fan leaves.
check ph, if proper that rules it out.
could be a bit of bun, but if slow moving or any tweaks lately i'd let it play out to be certain what it is before reacting. By 10 weeks in, you are probably providing near 100% of the plant needs and 750TDS is not extraordinarily high.. it's a generally safe range at which you could potentially feed every irrigation.
I can't see any of the sugar leaves in the pictures. I do see some damaged fan leaves.. mostly at the top and some at a node or two down from the top. Still think that's just light damage. 40-45DLI is a good chance of being too high for ambient CO2 levels. 45DLI definitely is.. 40 is borderline. Not all spaces have same co2 levels and your VPD is just as important to maximizing elevated CO2 use too.

Yellowing leaves top of the plant, bottom is green as grass. Both my northern light is doing this. DLI is tuned down to 30-35 on canopy tops but they still keep yellowing. Temps is 17 o night rh 55-65. Day 20 degrees and 55-60 rh. Late flower on both.

Maybe get a LUX meter, you can pick one up for ten bucks they work well for checking the light intensity. It's so easy to give too much. Plants up to two weeks old only want 15-20K lux, during veg no more than 30K lux.

I have the app Photone, as the lux meters for led here cost 10-20x more, it is really handy and calc DLI aswell:)
