Would water at 60F do this to my plants?

everything was going great till yesterday in these tents.
I have been watering around 3.0ec fine for the last few waterings.
I did notice my water temp was 60F when I checked it
Now they are curling down at the tips bad
I’m feeding floraflex in promix

Cold water will make them wilt,youll know in a few hours if thats what it was.How do you feed to runoff with no tray?Fix that and youll be good.

I don’t think I’ve watered to runoff in over a week.
promix is technically a soilless hydroponic medium...if you don't get a little run off at least a couple of times a week, the depleted salts your nutrients were bonded to build up and start to fuck up your roots. that said, it doesn't look like thats the case yet, but it won't take long if you don't get a little run off on a regular basis

They don't need anywhere near that EC, esp at that size. When you feed, just be sure to water to plenty of runoff so the salts don't build up.

Alright so should I just water with regular water to runoff to flush out the salts? Or should I just feed at like 1.5ec?

Your plants should be elevated in a tray with a bulkhead for drainage.Make it easy for yourself.Feeding high means high runoff,feed low and not so much.

im not a promix guy, i went coco a long time ago, and never looked back. i know in coco you never use plain water, always at least a little nutes, not sure if it's the same in promix or not

yeah, but all inert material is not the same, coco and perlite are very different, and rockwool is different than either, they have different ph zones, some make it more difficult for particular nutrients to be absorbed, and have different watering requirements.
in this case i'd say don't use plain water, use at least 1.0 ec
Same principals with peat,more water holding then coco so you can do a feed then water if your frugal with nutes.Or you can treat like coco just use a slightly higher pH. 6.2-6.5 ish.

3ec is way to high. The only people running like that are doing it in well dialed in commercial grows. Unless you’re running co2 in a sealed room with optimal vpd it’s gonna do more harm than good pushing that hard. Cut that back to 1.2-1.5ish
