1 Plant
Flowering stage now 29 days (66 days totally)
Indoor
Soil
The mix is 50% of soil + 25% vermiculite + 25% perlite. drainage is kermesite
The size of pot is 10L
LED light 150W (main) + 2*18W Fluro by Osram + 54W LED
Air cooled
The temperature is 29/23
RH is 6.5 into the pot. Out (bottom) measured is 7.2
Using the GHE Micro and Bloom
Watering is every two days (the schedule is feeding - water - water - feeding (each step every two days))
Mineral fertilizers used (GHE Micro 5-0-1; Bloom 0-5-4). doze is 2.1 Micro + 2.3 Bloom
The room is 1.2*0.6*2.5 meters

The problem is that some leaves have some kind of defects and becoming yellow.Suspects are over watering, pH or nutrients.

The issue here was caused by the vermiculite, that shit just sucks up any nutes and hold them like a sponge, then you come along and nute poisen your plants really well, reset the situation by a flush, no nutes until you see a positive improvement, avoid at all cost vermiculite in the future other than that ...a good mix with to much relience on bottles sewage, to my blog:https://www.rollitup.org/Journal/Entry/flush-baby-flush.27513/

I have smashed a bit the pot to get the soil cracked to let some oxygen in. The soil is almost dry so will apply the nutes tomorrow.

I have got my TDS finally. and the result is not that good:

1) from the tap is 1400 ns/cm (22.3C), pH 7.8.
2) from the tap after filer (not RO) is 1344 ns/cm, pH 7.9
3) from the tap but after 3 days with shungite is 1310 ns/cm, pH 8.2
4) from the water dispenser is 155 ns/cm, pH 8.0
4) distilled (from the shop) is 76 ns/cm, pH 6.5

All the measures have been done without adding the nutes. Will check with nutes later.

So it looks like we have found the root cause for this issue. WATER!!!

P.S. Comments, ideas, solutions are welcomed!

Your ec out of the tap is 1, 40 that is really high and I wouldn't be drinking the water. Mine is 0, 4 which is also fairly hard but it works ok. I would be using ro or distilled water and see how you go

I did a watering with the RO water and, later added the nutes using the same water (800PPM with nutes). Now my plant seems looking better. Still the issue with pH is not yet solved as I am getting 7.2 while adding water with 6.3. However I have moved from the dead point. Thank you so much, community, for the support.

Your reliance on reading the potential Hydrogen in your soil mix, is a fallacy, as how can that be correctly read, yeah play with your toy, if only to correctly estimate the local water, but see the soil itself is acting as a buffer between the nutes and the root zone itself, your method would be correct if you were growing in coco or even DWC but not soil!
...soil is far more complicated, should you resort to RO waters ensure you add a pinch of Calmag/ Epsom salts to each watering, but by far the better option is to just pot up to the next sized pot, ensure 30% perlite to pot volume to save you from this in the future!

Yes...you have a feeding schedule...this is how you water when incorporating into a feeding schedule...If you know you are going to feed tmrw (for example) and the pot is 75% dry...just give it enough water to make it till you feed her the next day. Runoff is bs imho. I water my 5 gal pots with 1 gal of water, an hour later I come back a have some dribbles on the floor. Thats about how much runoff you need, not water pissing all over your floor. The dryer the plant stays on top (IM glad you stopped spraying), will make for more tricomes on your buds. sticky sticky. when you water you are creating enough humidity in the room. My RH in my flwr is below 20%, when I water it will bump to 40 maybe even 50%

or just use water trays under your shit....below 20% rh will inhibit as well as "75% dry pots" hurting your yeild. mj is not that different from other plants. keep the , medium moist but not soaked allow some drying on top to keep the fungus knats down. but yeah dude your fucked. the buds at this point aren't going to form anything you want. start over. blance your nutes w/wattage. learn from your mistakes

either way plant science is real and the methods you described will inhibit photo synthisis. no reason to lower your yield if you dont have to. 20% rh is really low and supposedly a great environment for soft bodies like mites too. always strive for optimal conditions

at 50/50 soil perlite im thinking it cant be over watered,thats a lot of drainage!ph some water to 6,flush pot,add nutes at 25%,check runoff

Fresh photos of my garden. The issue has been decreased slightly since the pot has been flushed with water (low PPM). Looks like it is not possible to fix the issue totally and the harvest is near. can you please advise on when I have to start with Ripen?

that shit is ready for harvest more or less and nothing is going to change how that bud looks. how many watts and what type of light are you using. at first guess looks like to much nutes and not enough light to produce a sizable yeild

Don't know how I missed your post. I'm usually stumbling through here looking for people who are having issues I've had in the past. I 110 percent agree it's your water though. I attempted 4 harvests with a similar (city water) situation and after doing and indepth water test came out with similar results to yours. The long and short of it is, if your gonna continue, but Poland springs. You can use the RO but have to add cal/mag so the water is at a buffered state...or pay for the bottled shit. I saw that you had some sort of a filter, but didn't pay attention to what kind. I also used one of these in combination with the city water but can't speak on it's effectiveness as by this time (I think 6 months total) I was fed up with having water issues, packed up the tent, and moved.
Good luck, hope your next round goes a bit smoother.
