Please help

Hi, I'm now on my second grow and I'm having some trouble with one of my babies, she's a northern light. Also have a couple marks I don't know what they are on my sour diesel but don't seem to be affecting her much, the NL on the other hand seems to go really droopy but will pick herself up but only seems to be for roughly half the time the light is on and I'm on a 20/4 light schedule. I did have a little issue with heat, not sure what happened but it dropped down to 14c for an hour or 2 till I noticed and corrected it. I did flush my NL 2 days ago just incase it was anything to do with over feeding but she hasn't changed much since, just seems to have gone a bit pale? As u will see in the pictures the edges on the NL are sticking up which by research it could be a few things either heat stress, root problems or not sure if this is right but I'm sure I read could be too much cal mag??
Products and stats.
5 weeks and 3 days from seed
Using bio biz light mix soil and nutes
Grow, bloom, acti Vera, alg a mic, heaven and cal mag. Also using terpinator molasses. All at either 1/4-1/2 strength
Water ph is 6.4/5
Ppm going in is 685 and run off was 550ish (didn't write it down as I was stressing and forgot!)
Mars ts1000 at 19" above canopy, raised it as I wasn't sure if that was doing damage!
Temps range from 25c-22c depending on light on or off.
Humidity is between 40-45
I have tried to lst them both and they both seemed to take to it pretty well so I don't think it's that but I honestly wouldn't know.
Not sure if there's any other information needed? Thank you all in advance
First 3 pics are Northern lights
Last 3 are sour diesel

Good morning! A couple of questions:
What size container is it in?
How often and how much are you watering?
How often are you feeding?

Hi, they are in 3 gal fabric pots normally leave 2 days between each watering, I lift the pots to see if they need it. I have been doing 2 feeds then a water and I water till I get some run off.
thanks

Is it possible that this one needs water more often? Might just be thirsty. Hopefully someone far more experienced than me will pop by and take a look.

Yh that did cross my mind too but I'm so paranoid about over watering and getting root rot? But I did give her a flush 2 days ago so I know there was plenty of water in there and she still ain't picking herself up

 

[cubfaninmo]

Not sure if that is the issue or not. I under watered my first couple of grows. I had the same worry about over watering after reading so many warnings about new growers being prone to doing this. It’s a process that you are well on your way to getting the feel of through trial and error.

685 ppm for 1/4 - 1/2 strength nutrients seems high. How's your water quality?

The water I have sitting in the bucket is 410ppm that's been sitting there for 2 days now

Is that straight from the tap with nothing added to it? If so, that's not good . Assuming it's largely calcium, you're probably O/D'ing the plant and locking out some other nutes. You may have to look into an RO system.

Yh that's just water mate straight out the tap. It's mad cos my first grow I wasn't checking the ph or ppm I was just letting the water sit a couple days then feeding them with every water and they was sweet, I actually done really well with them yield wise but this one I'm trying to do it all properly and it's not going well! I know all strains are different and all that
