(Urgent) rewards for solving my problems :(

hi guys I wont post this unless I ran out of option. I’ve been growing for few years and never come across this problem before .
Symptoms:
- leaf turn yellow-green . Growth stunt
- leaf twist and curl . Especially top one .
- start to have yellow vein in the leaf .
My tap water run at 6.2ph . Room temp 25 celcius. RH 60%.
Feeding ppm <600.
I have 3 grow room at different stage and all of them ecounter this problem. Could it be the water ?
Anyone helps me get the right solution, I will send you a 24 beers bottle lol that’s the least thing I can do. Thank you riu community .

Looks like a couple things,
What's is your soil ph? How much in volume do you water and how often?
What are you feeding them?
@hotrodharley what you think bro ?

How often are you watering? I’m a beginner but looks to me like over watering and under feeding. What are you feeding and do you PH?

PH at 6.5 for best results and looks too dry and make my beer Miller High Life

Iron deficiency. What micros are you using? Check to see if Iron is there. Sulfur as well as they usually go hand in hand .

My soil ph is about 6.4 . I bought the plastic measurer in store to do it ( no battery). I water every 2 days . Wait until it’s dried so maybe not overwatering .
I feed them with the flora micro and flora growth . And vitamax . Thank you

Is it gotta be 6.5 ? My ph feeding is roughly 6.2-6.5 . And the picture I just took is the day After I fed them . Should I spray water to make rh go up? Thank you

You say you've been growing for a few years and have not had this issue before. I'm leaning towards some type of fungal disease.. Have a look at your roots, are they healthy ? I really hope you do not have the dreaded Fusarium - It is a type of fungi that specifically targets the leaves and roots of the cannabis plants.. I've had it once in the past and I had to dump the whole lot and disinfect every thing in my grow room ..

It is difficult to diagnose for certain through the pictures you have provided.. If all your plant in different stages are showing the same symptoms then a systemic disease is very likely..

Edit to add - rather than sending some beers..Maybe the value of the beers could be sent to a charity of choice..Just my tuppence worth!!

If I fix those plants, I am only 15 can you mail the beer to my friend ? He is almost legal

Sure anyone helps me solve this will get beers, or the donation to charity group such as the guy above suggest.
I’m pretty sure flora grow and micro contains all the things needed . I just spray them with bug be gone (30mil/liters) to eliminate any possible bugs. This problem is driving me crazy. I just check my ph after adding nutrition, it’s 6.2 and 550ppm. The growth is so stunt . Normally I only veg them 4 weeks in 2 gals pot. Then transplant to 7gals pot for 3 weeks. But at 2nd week of the transplant , the growth completely stunt for next 2 weeks. The leaves keep getting yellow-green color and twist . My whole crop will be doomed .
Is the ph best at 6.0? Will 6.3 cause any nutrient locked up? I’ve tried so many solutions and still no results.
And btw the strain is black diamond

Here is the leaves . The veins are turning yellow. And the color is turning yellow-green

If you are a cop I'll take Sam Adams

6.2 is too acidic for tap water. I would triple check that, first calibrate your pH meter, perhaps use a different pH measurement tool.

Your tap water may be different than his.

Mine runs at 7.5, 150ppm

My buddy down the road is at 6 and 0 ppm no filter

If you're in the U.S., water pH is supposed to be between 6.5 and 8.5 by drinking-water regulations per the EPA. Flint, Michigan had an acidic-pH water problem! Your buddy might want to report those figures to someone, again if they're believed to be accurate figures.

https://en.wikipedia.org/wiki/Flint_water_crisis

"Acidic water makes it easier for the lead found in pipes, leaded solder, and brass faucets to dissolve and to enter a home's drinking water. Therefore, public water treatment systems are legally required to use control measures to make water less acidic. Plumbing that contains lead is often found in buildings constructed in the 1980s and earlier.[81]

Canada. Its spring water from a mountain

Yea I’m from Canada . It’s 6.1 I just measured. At this rate maybe I have to chop down to start new crop because those plants are too weak to enter flowers stage. Too small also.

i see one issue, but can you take a couple pics of the entire plant visible and one looking straight down as well from the top, but in natural light! This light makes it harder to see! Also, kindly add exactly what you are growing in, and how much are you feeding when you feed.
