Why are my tops leaning over?

[Harpua88]

I had a similar problem with my plants, spent some time going through the plant food etc, I gave them some Epson salt, because there was a low amount of magnesium in my dry plant food.

Does your leaves look like this?

It's very hard to tell, and give advice......on lots off things, without knowing more about your situation, the soil, your watering, your light, feeding if any, etc.......it looks like your plants are in a small pots but it's hard to say.

Best is to start a new thread of your own, where you can add lots more info.......you'll get good answers and help.

Those leaves look a bit more strained than mine, mine start out a light but then turn a lush deeper green as they grow out. But the tips show a little nutrient burn like yours, but just the tip

I agree its hard to tell and give advice, reading the comments and looking at the plants makes me think it could be "magnesium deficiency"
other things could be the cause.
My plants have recovered and the new growth is looking good.

Your plants just reached their DLI for the day. If they are looking droopy for more than an hour or two before lights out, adjust your light so that they aren't receiving as high of a ppfd. If your light has dimming capacity, lower it 10-20% otherwise raise the light off the canopy 12 inches

The light was 24" at 60%, I tried more and less distance, light. Even at 40% and 30" inches they reacted the same. More water has helped.

What did you do that gave improvement?....if anything...

If light strength was the issue......it's not instantly fixed. If a little damage was caused it's going to take a few days, maybe more for the plants to get through the damage done, even if it was very minor......and the new growth to be happy with the reduced light.

Same for overfeeding. It'll take a few days of backing off for them to respond well.

This is an hour before lights out this morning, 2nd day of transition. They are looking a little droopy this morning but they will be up and praying again by tonight when the lights come on. They grew almost two inches yesterday in the dark. And no they are not droopy from overwatering, last water was 2 days ago and the top of the soil is mostly dry.

 

[F.Dupp]

They look healthy. If they look droopy at any time other than before lights out, or when they are underwatered, you could maybe check your vpd. I know that if my vpd gets too low my plants will look a bit sluggish. But that's usually on a strain by strain basis.

 

[Mikedin]

That's good. It is a source of silica. As for critters, it's usually used at the top layer of the soil. It controls insects because it scratches their bodies and legs, which releases moisture from their bodies. That loss of moisture kills them. It only controls critters that crawl, though, like ants. I learned about that when I killed an ant hill with it.


They do look healthy, except for the purple coloration on the stems. That can indicate one or more problems. I'm not sure what might be causing it. Some nutrient deficiencies can cause it (magnesium), as can temperature or pH. If they were mine, I think I'd just focus on giving them proper care and letting them grow. A tablespoon of Epsom Salts in the water, for magnesium, might be worth a try, though.


65º is a bit cold for them. I didn't see a heater in the tent. It might help to keep the temperature above 72º or so. 85º is fine. I set my controllers to increase the exhaust fan when the temperature is 82º.


I don't recommend watering based on a schedule. My preferred method is to use a soil moisture meter to check the moisture level at or near the bottom of the pot. That's where it matters most. I water when the meter reads near the bottom of the scale. I also look at the plants and compare what I see them doing with the reading on the meter.

I prefer the pick up method, I also keep a hydrometer inside the canopy, started to notice when I see the hydrometer go from 50% to 48% it’s time to water, was a guess at first but seems to be right on with bucket weight

I still find the right time to water difficult, after decades of growing, so I look at the humidty, to see if that's gone down, keep a diary of the last time I watered, check the top 2-3" of soil and then slide a thin stick in the soil just to make sure the soil dry.

Water, and the plants tells me.
within 5 minutes the fan leaves tips drop(claw down), the more effectived leaves the more I have overwatered, if the leaves don't do anything, good timing, best timing is when the leaves slitly lift and the plant looks happy, taking about 1/2" praying.

Imo getting this right has a massive impact on the final crop size as it directly effects the plants health and uptake of nutes/water.

Proper watering techniques are probably the largest amount of grow fails for new growers, knowing how to watch the leaves make a massive difference in decision, like I said above the RH is a big tell all (especially once humidifiers are removed and the plants produce their own humidity) I see that Rh drop and boom it’s a no brainer, plant isint transpiring enough, she’s thirsty, it’s also important to note, if you’re using leaf pray (I do this as well) is to make sure that it’s at the same time each time you use that indicator,

Learn what the plant normally does at that time of the day is it praying when watered and happy? Is it normally getting ready to sleep leaves drooping down time related instead of water related. So you walk in at that time and your RH is down 2% and your leaves are drooping SLIGHTLY then you know it’s time to water

I’ve found the combo of
RH
Observations of current plant status
Leaf droop
And the ol pick up method

its never steered me wrong yet lol, problem with pick up method is, i scrog so I can pick the plants up about 1/2” but it’s enough to be able to tell if they are thirsty

I forgot to say, I kind of tip the pot in mid/ late flower instead of lifting it vertical, find it easier to tell.
maybe the plant can handle 38 moles and at this stage the leaves drop, guess this can also do the plant damage(if i get too much sun I can head for the shade) but that's another topic.

Agreed, it sure if it was here or another topic I just read lol, but someone else was saying if the plants met their DLI they will start to drop back,

For an example for OP my 4x4 has a FD6500 640w light, I’m 3 weeks into flower and they are happiest at 45% power, (around 300is watts) if I crank that light up I’ll toast those girls in hours lol, but I’ve had other strains be fine with 800w on them and still looking like they want more, a lot is genetics I’m sure depending on where the strain originated and what it’s natural environment was like, it’s still going to want, we just have To manipulate our environments to make them happy, I never over worry about how much power I’m giving them, I start low, (20-25%) and work the light up over 3-4 days 5% at a time (per day) until you see drop back after 6-7 hours, then I back down about 5% or lift the light another 3-4” once I see that perfectly flat canopy of leaves I know there happy

Edit, ‘‘twas here haha

Your plants just reached their DLI for the day. If they are looking droopy for more than an hour or two before lights out, adjust your light so that they aren't receiving as high of a ppfd. If your light has dimming capacity, lower it 10-20% otherwise raise the light off the canopy 12 inches

What did you do that gave improvement?....if anything...

Just seen this, I brought some Epson salt, added 1 tsp to warm water, mixed well, and sprayed the under side of the leaves, I could see improvements the next day, top dressed each pot with 2 tsp and watered when they need it.
I will top dress again in 7-10 days, IMO less is more.

I meant the op, Dannyo and the drooping tops.........this thread is so confusing.....ha!!

I didn't know you had a problem but what is it that foliar feeding epsom salts corrected?

 

[BudgetGrower]

Green veins on yellow leaves, with the odd brown patch on some lower leaves, the new growth looked more healthy and some of the faded leaves(light green) looked greener.
Anyway its back the op from now on lol.

 

[DonnyO]

It's all good, I'm learning from everyone's experiences.

I just checked and it looks like they need water today, on day 3, when the last two times it was 4 days. Day 3 of transition.

 

[Cannaburg]

As someone who has ALWAYS veg under 24hour light.... I would honestly say at a quick glance you need to up your feeding/watering! Especially during flowering.... there are times I would have to feed my 7 gallon pots 2 gallons of water every other day!!! Looks like you have thirsty girls plane and simple!
