Healthy plants discolored and wilted

Ppm is about 900. Ph is 6 or so. Reservoir temp of DWC is 62 degrees Fahrenheit. General hydroponics flora nutrients. Went from healthy to wilted over the course of a few days. One plant is discolored as shown by picture. Wilting before the reservoir change we did a few days ago. Any ideas as to what could be causing this? We have a more accurate ph reader on the way as we've only been testing with liquid testing drops.

your temp. seems ok. ph could very well be the prob. did you scrub out the rez when you changed it out? how are your room temps. lights out?

900ppm at that size? Is 200 of that cal/mag? Try half of their recommended amounts. 400-500 w/ some cal/mag. How far are your lights? What kind of lights? What strain?

I think your ppms are a little high! if your ph is off the plants could be locked out. they don't look Real Bad! are the bubblers working their ass off? do you have nice whitish roots?

Thanks for the replies everyone.. When I did the res change I swapped all new totes and bubblers in. Just makes it an easier process for me. So everything there is new and clean.
Currently giving the. 24/0 so lights always on. Should i do 18/6?
Roots were a bit off white which is what prompted me to do a res change to begin with. I also added the "heisenberg tea" (zho mirco ewc and molasses) they seem to be white and healthy. Slightly off color still but I assume it is just them being colored from the nutrients. However the root growth is extremely disappointing. Ill get pictures of them later today!
Ive been gradually raising nutes and haven't seen any nutrient burn. My tap water is 250ppm from the faucet. Extremely high :/

Bubbles look good to me. But this is my first grow. Will also snap a picture of the reservoir so you can see the bubbles.

Im mainly concerned with the wilting.

Forgot to answer a few other qs.. oops

4x2x5 grow tent
600w dimmable light. At 75 percent. (Its winter and cold. With 50% temps averaged as low as 62 in the tent).
light is about 18 inches away
6 inch cool tube with a 745 cfm 8 inch fan pulling air through. (On a speed controller. About 75%)

I have 3 different strains. Planning on running my next grow with whochever strain grows the best for me. Master Kush (attached here) Flo (the one with discolored leaves) and blue dream (the other plant in the original post)

Plants need to rest my friend. 18/6 will be fine. I personally like the res temp, couple more degrees wouldn't hurt anything. I don't know if I would go so far as to say the roots are discolored from the nutes, but maybe. how high is the water level in your res, are any of your roots submerged in the res.......

a starting ppm of 250, added to 900 is wayy too high. you don't need to change you light sched. but a lot of folks like to have some dark period. your new ph meter will be a big help. i'd back ur ppm down to 500 or so.

Water level is just slightly under netpots. All the plants have roots that are in the water. The roots 2 of the plants (master kush and flo) have two or 3 solid roots with hairs that are fairly long. But the blue dream only has 1 longish root but many more just poking out of the netpot. Is that typical for plants that i started from rooted clones january 2nd?

Hey guys I appreciate all the help! My nice ph/temp meter got here, I'm glad I fored over the cash for a nice one. Turns out the water that I thought was at 6.0 was actually at 5.2 in one tote and 5.3 in the other. I'm guessing that was my issue??? I got them both at 5.80 now, ran some of the red eater through the net pots to ph the roots at the base, and I'll see how they look in the morning. I trimmed off a bunch of the shitty leaves on the Flo plant, good idea? Or did I fuck up?

Gotcha. Plants look the same as they did yesterday. Checked the ph and it climbed up to about 6.2 - not sure if there's something buffering the ph change or if i have other issues. Anyway, I added a touch of ph down and will check ph every couple of hours.

Brewing more heisenberg tea to toss in there, im scared of root rot!!!!

Reduce the ppm until the plant is much bigger. Also you cant really have the ph at "6 or so" it has to be 5.8 spot on.

You wont get root rot with the res at 62 and the ambient temps low.
