Plant probs with pics

Night temps 85
Day temps 67
Aero/hydro hybrid
Bunch of 600 watt hid
Hard water

What’s your ppms and ph?

Ph goes in about 6.3 but it seems to drop fast down to the low end... 5.9 5.6 ish.
Then i add in higher ph nutes to balance.
Ppm?? Im doing 50ml 100ml lucas ratio.

I dont usually check but i did a week ago it was roughly 400 of hard water and 1300 after nutes

So you lights on temps are lower than your lights off temps? Whenever I have seen them claw down like that, and weak growth, it's been a PH crash.

Heat and light stress

He's saying his day temps are 67?... That plant does look pretty close to an HID light tho.

Then it might be heat stress.

Holy shit... The ph for these 2 things were around 7000. Yes. 7000. Cheap tds meter but thats what it read.
My tap is around 400 and with lucas ratio, its about 1200-1300 total..... So about 800 of nutes...

I pulled all my resevoirs and replaced with new ones that are a few gallons bigger..

I filled with the following:
3.33 ml per gal micro
6.66 ml per gal bloom
4 ml per gal cal mag.
20 ml per gal 3% hydrogen peroxide
Ph around 6.3

After running through the system, it immidately picked up 500- 600 ppm of shit from the roots and root chamber.... Pvc manifold.., whatever...

Ill check again tomorrow....

Honestly I'm surprised your weed is not on fire. Your plant is inside the hood of you 600watt? Mine burn and yellow when they are less than 12" from my 600. Need to get that light up a lot.

I bought some cheap blurples to get me by when I had issues with spacing between my plants and light.

This run i had huge stretch and had to buy a taller tent and do some other mods so I can get enough distance.

Gotta do what you gotta do
