How cold is too cold?

So I’m growing 12 plants that are about a week into flower. Everything was going great until my plants looked kinda wilty and sad and almost stringy. I cannot think of anything other than the temps. About as hot as it gets is 76 and at night it gets as low as 60. Everything else is spot on from my recollection. Please help!!

That's not to bad for temps.. although 60 is a tad low but shouldn't cause to many problems..
Without grow details like soil type, feeding watering schedule, type of lights it's going to be harder to give you any short answer..
But from what you're describing it sounds like over water and lack of light.. ..
Please post up some pics of your plants and what soil type you are growing with watering schedule

Are you growing in coco? The plants don't look bad.. I do see the slight wilting you're talking about..
Plenty of light so that's good..

Maybe the low night temps are causing this but it's hard to say for sure.. any way you can put a small adjustable heater In there with a timer? Just to see if that resolves your problem..
I'm not familiar with coco so I'm sure someone here can give you an answer to solve this for ya..

The biggest issue I see is the difference in your canopy height. The plants look healthy but they’ve been left to grow in the natural apical dominant way. That’s ok if you’re growing outside b/c the sun moves around the plant, but inside the only light is coming from straight above. So the tops of your plants are getting significantly more light than the rest of the plant and the individual plants vary quite a bit in size/height.
I’d suggest some training to level out that canopy…….it will increase your yield noticeably and also eliminate the loose leafy buds that you get from the lower portion of the plant. Tie them down, super crop (it’s dick simple) and open those girls up……spread em out and enjoy a sea of tops. It’s still early enough in the grow to make some major improvements.
HLG makes one of the best lights money can buy……use that space to its fullest potential and fill it.
I’m no expert and have my share of issues but things turned around for me when I started training and getting an even canopy. The pic is my current run, week 6/7 of flower……I only have a 2’x6’ closet w/ 8’ ceiling and generally get 14-18oz (dried and tightly trimmed) per run, which is usually 3 plants.
Just my 2cents. Good luck. IMG_8002.jpeg

You can rule the cold out.
Your temperatures are relatively balmy so no worries in that department.
Ouch. What’s your light?

You’re too cold for sure. I mean to for plants to grow as it grows no matter what but to get optimal results with led you should be shooting for 80-84 hot time, and 75ish lights off. These numbers directly corresponds with relative humidity as well. So typically a hot led room will have 50-70% rh through vegetation.

with these changes you will see dramatically faster growth, greener growth and better pest/disease resistance.

Now they don’t look awful but they just look and feel thin and the interior of the plant is sort of undeveloped and looks like slow going
If you want to make them denser and thicker, up your fans/ air movement inside and keep topping them. Pinch the top from the end of every branch, it will encourage more outward growth further down on each branch. You can keep doing this as long as you want and they will get denser and thicker and bushier while keeping them at that sort of hight.
Personaly i think they look great as they are, your doing good. Any thicker with how close they are, when you go into flower your going to have to keep a good eye on bud rot and are going to need quite alot of air movement. They are already groing into each other, going into flowering that will double. Might be an idea to open some of them up and tie back some branches or get a screen on now.

Well, my tent gets down to 64F each night and 80F when lights are on. I got a beast of a Apple Fritter that dont seem to mind but my Durban Poison auto dont like it much.

I got a photo fem that been has not seen the high side of 70F since the cold set in. Its not looking too shabby. Nights in that room are a couple degrees cooler at lights off.

You know what hates the cooler temps?........spider mites :D
