Tops of Plants Drooping

(edited: added pic, scroll down just a bit)

So right now I got some plants under 1000watt hps/MH combo bulb, 3 of my bigger (Biggest I think) plants have there tops, and just the tops like the new foliage, drooping, pretty dramatically. At first I thought it was underwatering so I changed that, it fixed one plant that I thought was bout to die because how bad it was drooping so I increased watering to the drooping ones, now there still drooping but pots are heavy so Don't think its water. Then I thought it was the heat, so I adjusted the heat to make it cooler throughout the night, still got same problem. And lastly I re-arranged my plants so that the ones with drooping would get more ventilation cause I thought this might be a problem too but it hasnt changed anything since I did the re-arrange.

This morning I went in there and tops of the 3 ones I was having issues with are still looking really bad, I've noticed a slower growth now since these problems have started too. I don't know what to do from here, I know I don't need to increase watering anymore and I know I shouldnt decrease it either because there drinking water so fast that I did almost lose one to letting it sit to long dry. Only things I can think to do is maybe transplant into bigger pot for more nutrients since I thought maybe there starting to get root damage and maybe have used up the nutrients so far in the soil?

This is my first grow I"v ever done so still learning a lot, any advice/help is much appreciated. The plants currently with problem are easily above 1 1/2feet-2ft tall, tallest one probably bout 2-1/2. And 2 of them are super bushy and grown out, maybe 2-3 feet around? Like I said, this problem is only with 3 of my plants in the room, rest are doing great it seems. - Oh 2/3 of them with these issues are auto-flower, the other one is full-term but its also in its flowering state right now. And if that changes anything too, everything is currently in flowering about 3-4 weeks into flowering. Anymore information I need to post just let me know! thanks!

Pics help the most man. Good description of what you've done thus far. If they are still heavy, then over watering might be the issue initially. What is your medium, your watering/feeding schedule your ph, Sativa vs indica...etc? Relative humidity/temps too?

if you're still in party cups or something tiny, you need to up pot
otherwise.... - is the drooping growth fading? - light intensity
not fading or whole plant paling to more electric colors of green - uppot

bu yeah - pics and pot size/medium will help a LOT
how far off those seedlings is that thousand?
suggest 20-24 inches first 2 weeks

you need pictures brochacho

I'll post pics here pretty quick need to get some first. And pot size is 3gallons about, i forget exact but i know its bout 3 gallon pot size. And using foxfarm/organic soil mix in them. And plants are bout 30 inchs from light, tallest one probably bout 24, but its experiencing the same issues as the ones that are 1 foot tall and 3 feet around, so those ones are closer to 30-36 inchs from light and experience same problem as one 24 inchs away.

And I still really don't think its water, I know how to check if they need water or not, and I"v been doing that, I've already been through a process of less watering, and a process of heavier watering.

Results on that was, "reduced water" - 1 plant top started to bend over and all leaves fell to side as if were dying. (Thought it was dead but it came back luckily !)
"Increased Watering" - Obvious drooping because of over watering, so pulled back.

Just doing watering depending on weight of plant for last 4-5 days and issue continues to persist even with what I think a perfect water schedule, they're retaining for bout 2 1/2 days and usually water right on that 72nd hour or so, some less, some more obvioulsy, just doing all of them different right now cause they are all in different types of needs right now.

Good drainage? Pics will help us.

Sorry lights on, and this is just one stalk of one of the plants that is doing it now, other 2 are looking good right now but I assume by morning they'll be drooping pretty good again, they felt fine on weight so I didn't apply water. This one I'm taking picture of felt fine on water also, but I can tell it'll need watering tomorrow afternoon or night. This drooping is actually kinda not as bad as its getting by the mornings either. With the location I can't be checking on it 24/7, so usually I do a midnight check and check again around 8-9am when I get up, so there is an 8 hour period that I don't check on them but come back to drooping plants. I'll take more pics in morning see if it happens again. Been dealing with this for about a week now trying to balance stuff out maybe they will still look good in morning!

And far as humidity, I can't tell, I've put to much into what I got going so far so still waiting to buy some stuff! Like I said, first time attempt here so I was clueless at first but now I've got the idea just been fine-tuning my equipment/set-up since I seemed to miss a lot on the first set up.

And yea my drainage has been amazing since day 1 for every size container I've used so far. Never had a problem with that that I could tell

This morning plants were super light and drooping again didnt get pics cause didnt have camera on me but I'm starting to assume this is an underwatering problem and that the plant is experiencing its issue during the 8hour period I'm not checking on it. Going to try and fix this by doing all waterings at night now so that they have that water on hand through out the night when I"m not there, if one seems to be a tad heavy and not need water pretty sure I'm still going to add small amount of water so it'll make it through night without causing all that drooping stress! And hopefully at the same time I won't put over-watering stress on them either. I only water bout 2-3 times a week depending on there weight guess I'll just have to add little more water to each watering or reduce watering per watering session and add more actual waterings.
