Constant Drooping Leaves - Total Noob Need Help Please.

[TheBug]

Problem: Leaves Constantly Drooping

Medium/grow method: Happy Frog Soil with 35-40% Added Perlite

Feed: and supplements used: Advanced Nutrients Micro/Grow/Bloom & Voodoo Juice

water source: Tap left out at least 24hrs and then pH'ed to 6.5

Strain/age: Fast Buds Green Crack/Almost 6 weeks old

light used: 600w HID(Initially with MH bulb but now HPS)

Climate: Indoor 70-75 degrees F and a RH of 40-45%

Additional info: I am at a total loss to do with this plant's drooping leaves. Up until about two weeks ago this plant was my most vibrant, healthiest and strongest plant out of the four different plants(all different Fast Buds strains) that I am growing on my very first grow. At about four weeks in with the plant very healthy I gave her the first feed using quarter strength nutes and watered until run-off, about 2 liters. The next morning I woke up to find her completely droopy.

Seeing signs of nitrogen toxicity in my other plants I thought it was the nutes effecting her. So I ran some straight ph'ed water through her, about three gallons. She just stayed droopy. So after looking around the internet the problem that most looked like my issue was over-watering. So I let her dry out until the soil was dry down about 2-3 inches, checking with my finger. She was still droopy but I think she looked a little better. I gave her some water and it seemed she drooped even more again. So again, researching I'm still coming up with overwatering. I then let her dry and dry, until this morning when I lifted the pot it was dry as a feather. So being concerned of under-watering I gave her a liter of just pH'ed water. Tonight when I checked on her she seemed a little perked up but as you can see in the pictures I took tonight she is still droopy, has some yellowing leaves, purple stems & leaf veins.

So without trying to guess what the issue is myself anymore I figured I would come here and see if anybody could help me recover her. I am totally frustrated and don't know what would be the best approach. Seeing as how the water this morning may have perked her up I was thinking of watering and feeding her again to run-off, but as I said I am just guessing. Any help would be greatly appreciated and I thank you in advance.

Sure does look like over watering to me..I'm no expert ..I call @Waira for problems.
Could be a root problem that was already there before your flush...as in, possible start of rot due to over watering , I notice your smart pots are in catch pans, if they are not elevated in pans, water can settle and cause root rot. They need to breath underneath for more healthy roots. Also, you got to be careful when you let them go to dry when you have a problem going on, you could stress them out even more , could stress them more. We'll let the seasoned guys/gals chime in......good luck!

When you under water a plant the stems will tend to remain quite perky whilst the leaves will just start to flop straight down whilst looking limp and lifeless.
When you over water your plants they will droop or curl/arc from the stem to the tip of the leaves if that makes sense? The leaves will also appear quite fat/full rather than limp and lifeless.
It can be hard sometimes to differentiate between the two and it’s sometimes a fine line between the two!

Also beware of heat stress as that can also look like underwatering sometimes causing leaves to flop or go limp but If your temps are fine you can easily rule this out.
Try to keep your ph between 5.8 - 6.5.......I tend to play it safe and keep mine between 6-6.3 now just to allow for small fluctuations or errors on my part.
You’ll also find that your plants leaves will loose their perkiness slightly during lights off/just before lights off & just after lights on so it’s best to assess your plants half way through lights on for more accurate diagnosis.
You mentioned red stems........I’ve found a smallish dose of cal mag once I start to see that unmistakeable hint of red/purple usually helps and will help your new growth turn green.
Again, I’m no expert but I hope that extra little bit of info may help you until @Waira rears his/her head!

Way over watered imo but also probably root issues now to go with it. I would leave it be for a week without water then go back with 25% peroxide and 75% water ph to cleanse roots. But no more nutes either its so dark i wouldn't feed a thing

I agree 100% she looks over-watered but that is where I am stumped. She only had one soaking watering, making sure prior to that she was dry using the finger method, and she instantly drooped. But even if I concede that that first watering to run-off and the flushing I did afterwards(post-drooping) over-watered her, drying her out doesn't seem to be correcting the problem. Prior to the pictures above I had her sitting for at least a week on top of the catch pan inverted with a fan blowing directly on the pot. I then kept lifting the pot until it was totally light. So light it scared me that I added 1 liter of water just in case while I try and search for a solution. I have 3 other plants, different strains, that I watered exactly the same and none of them behaved like this one. I am getting a moisture probe in the mail today to use as a double check, but I think I've got a good feel now for the pot weight.

As for heat stress I can't be certain because I am not 100% knowledgeable regarding what it would take to heat stress them. But I highly doubt it because I am in the Northeast US in my basement(where it is in the low 50s) and I need to keep the lights on 24/0 just to keep the tent at 70-75 degrees and it never once reached 80 degrees.

I do appreciate all the responses and help, thank you. I can't express how frustrated I am with this, none of the straight forward stuff I am finding on the internet seems to be leading me to a solution.

I have one that droops sooner and longer, are you checking at same time everyday?

 

[Padawan1972]

Gonna sound weird..but, any foul or off ,weird odor from bottom of pot? Might need to get your nose close.

 

[Arthur]

Your in your basement, are your pots directly on your floor?

 

[TheBug]

I am regularly checking the plants at two times a day, morning & evening, but have checked them additionally at other times of the day and it is always drooping.

I will give the pot a sniff tonight to see if there is any weird odors.

The pots are in plastic catch pans and then I had placed a layer of foam insulation underneath the tent about 2 inches thick to insulate between the concrete floor.

Thanks again for the replies!
