Downward curled leaves

I've tried searching the symptoms everywhere, and haven't been able to solve this. Sorry for another "one of those" threads, but I did try to figure it out myself. Thanks

Leaves are curling down, started after the first week of flower. I thought at first it was over watered, but I've been letting it dry to the point of drooping for the last week and a half. I also have two other strains on the same schedule as this one that look great.

-Week 10 and week 3f
-78-80⁰f 50-60%
-Happy frog soil
-General hydro 3 part nuts, using the low feeding chart. Calmag every second or third feeding.
- Well water, pH 6.4-6.6
- 5 gal fabric pots

I have a suspicion that it's the cal mag as well. I had very similar looking problems on a single plant I had that I thought mag was the issue. Once I gave cal mag it started doing the same thing. I stopped giving it and things seemed to have settled down, but I will warn you the leaves won't exactly be 100% again. Best you can do is hope it doesn't progress worse.

Plants drink more in flower don’t they? If you’re holding back on water could they just be thirsty?

how often / how much are you watering? And are you watering slow enough

No, just waiting for the lower fan leavs to slightly droop before watering, thats what I've been doing for the last three/four waterings (week and a half ish). And I was only doing that because it seemed like a symptom of over watering.

However I haven't tried to increase watering.

Well hasn't been tested, but I do know that its high in souliable iron, nothing I can really do about that at this point, other then percipitat the iron out with an oxidizer (bleach or h2o2). Which doesn't seem like a good idea. And I have no real understanding of how high iron water affects plants

Just a quick couple of ideas...

Did you change the lights when going to flower? Like from X to LED?

When was the last time you calculated your pH pen?

Are your plants sitting on a cold hard surface?

I'm confident that I'm watering slow enough, the lower fan leave dont appear to be thirsty, except lately right before a watering, because I've holding back...

I'll try to up the watering and see what happens

No change in lights

pH is calibrated every use.

It is sitting on a cold surface, 65⁰ +/- concrete floor.

Only if the pot feels light. I’m still a beginner, hopefully someone with a better understanding than me will give a direct answer.
But what light / what distance? Definitely effects the canopy the most

I would suspect it may be that then...if it were the calmag and N I would expect them to be a lot darker green to go with that drooping. If you can put them on short risers and insulate them from the cold I think you would see improvement

I'll give a shot.

Think its salvageable?

Thanks!
