New help fast!!!

[Donmagicjuan]

This is my first grow, the plants are at day 19, they were growing great until day 10 where I saw the bottom leaves were starting to get yellow and brown spots, Some of the leaves were also twisting and still are, I havent ferted until recently I have them 1/4 Strength of Liquid Earth: Vigor and 1/3 of Liquid Earth: Grow

I know the plants are not being overwatered or underwatered because I have alted them sevral times to check if thats the problem. I think it might be a PH problems but im not sure if ph causes drooping in the leaves. If it is PH I have Dolmite lime but not to familiar with how to use it.

My camera Sucks but you can see what im saying about the problems.

Overfed maybe. Overwatering maybe. You do have holes in the bottom of those cups right? If the plant is wilted, even though the soil is moist possible culprits are >> Over-fertilization, soggy soil, damaged roots, disease; copper deficiency (very unlikely). PH problems can give the leaf some twist.One of the first signs of having a slight ph problem is, your plant having part of the leaves kind of twisty, spotty with brown, yellowish, red spots within each other.
Sometimes they don’t have to have all the colors, they could just be spots that have yellowish brown, or just reddish brown and can happen anywhere on the plant. Mainly starts on big fan leaves then goes to little leaves. When this happens you need to check your soil ph, water ph before and after adding your nutrients. One of the biggest causes is adding nutrients like earth juice; they take the ph down quite a bit. Also can happen when you add bone and blood meal to your soil, that will throw the ph off as well, so it’s smart to test the mix before putting your plants into the mix. After the spots happen you will soon see nutrients being locked out, when that happens DO NOT ADD ANYTHING TO FIX THE PROBLEM UNTILL YOU GET YOUR PH FIXED!!
What is your PH??

First one point I'd like to make - ALL of your plants are drooping the same.

Since each plant is separated from the other it means something you are doing is causing this. I noticed in your post that you stated what it couldn't be, mainly watering, and you had checked.

In my experience the ONLY time I have had plants wilt like yours is:

1 - Immediately after watering
2 - Lack of water
3 - Too much water

That's about it my friend. Root rot is generally caused by over watering, so I dont even list it.

When my pH has been outta wack the plants would show the typical signs of lockout, not drooping like this. And when the soil was too hot (high EC) the plants would turn REALLY green, burn and then begin to droop at the end.

Droop typically = 1 thing... over watering/under watering.

Thanks for the replies, I took your advice with the watering and decided to give them extra water today to see if any change would occuer, about 6-7 hours later I check on them and the plants looks much better. It is really weird though, I water them till there is runoff at the bottom about every day or two, the soil seems to dry within hours its really confusing. Could it be the such small space with 10 30 Watt HPS lights? I also have a large fan for intake which isnt shown in the pictures, About 4 times the size of that smallfan for out take but I set it a lot lower speed and farther away than the plants. Could the yellowish/Brown spots on the bottom leaves be due to a week or two with being underwatered? Could the leaves become yellow/Brown from touching the soil?

Ya know, that brings up a good point right - what medium are these in?

I assumed it was soil - but what kinda mix and how much perlite was put in there. You can get soil that holds water like a non-soil medium (such as vermiculite) or you can get a soil that only needs water once every 10 days.

The reason I mention this is you are watering every day. The normal rule of thumb for transplanting is if you need to water every day the plant needs a new home. So I'd HIGHLY recommend transplanting, unless you are using a very very light soil mix in which case daily water would be needed.

So now that I know more I'd say your issue lies with either the soil mix or the containers. I dont believe your lighting is causing this - and please keep in mind, every time they droop like that they are beginning to go into shock. Shock slows down growth and promotes hermi's.

The browning of the bottom leaves are a sign of the plant being hungry. She's feeding on herself as her surroundings dont have much to offer.... give that lady a nice dinner!

Good luck - Hope I helped!!

I just went through the same problem Don, yellowing, spots, then started getting crispy. I was in the same time frame as yourself, so I decided to transplant.

The roots were so tightly wound in the bottoms of the cups (the roots were still nice and white though) that I thought for sure they were gonner's.

I just transplanted yesterday and they look much better. I'm only worried about stressing them so much that they turn all male on me.

We'll see!!! Good luck!!!!

 

[JJScorpio]

What are you using for lighting? Have you used any nutes yet?

 

[Blackmelo]

Hi Don, you need to check your ph before you do anything else.
Those leaves are not drooping like the regular droop after watering, the whole plant structure is bunched up so I am highly suspecting a wrong ph. The fact that the leaves arer now starting to get problems just confirms this.
Overwatering can cause this too but then you said that you are sure you are not overwatering...

You do not need to invest in a ph meter, a ph tester fluid will do the job but you do need to monitor your ph.

ps: they could do with a repot too

 

[Donmagicjuan]

Ok so I put them outside today in my spot and in 4.5 Gallon Pots they were very root bound, which was probably why they have been drooping a lot. I put them in tonight so hopefully tommorow they arent as droopy and Healthy. If I had the plants going 18/6 mostly would they start to flower once at 14/10?

 

[Donmagicjuan]

Also since they are in 4 1/2 gallon pots, how much water would the plants need and how frequently.

 

[D-teKX]

Hi Don,

What probably was the main reason is a too small pot/container, combined with too less watering. When the substrate (in this case soil) will become too dry it will pull all the water out of the plant, therefore it will hang down. Also the leaves will become crispy because of this (all the water is sucked out). Because the container is too small the lower leaves will die to give nutrients to the new sprouts of the plant. Best thing to do is to place them in a bigger container, which you have already done. And remember a little plants will evaporate about 3 liters of water/square meter per day!!! Adult plants about 5 liters/square meter per day!!!

Peace

you mentioned it is a small space with ten 30 watt hps lights. What are the temperatures running at? As far as watering goes don't try to adjust that to your schedule (like every two days etc), just water them when they need it. The easiest way to gauge that is just lift the container, when she is light give her a good drink.

Another Problem...

Another Problem...

Ok so today I thin kis the 3rd day they have been outside, When i checked up on them this morning I noticed a Large Spider Egg in the soil. I knew there were spiders in the area from the first day being in this spot but now theyre on my plants.

How big are Spider mites? I hear they are very small but these things look like baby spiders that will grow to be big.

So far its just one plant out of 10 (I planted a seedling Yesterday), What would be the easiest way to get rid of them If I waited till tommorow would the plants be alright.

Im going to the spot again to check up and take pics so an update will be very soon.

-Don

If it is a regular spider then leave it there for pest control. Spider mites are very tiny. Look in Stitch's guide to see a spider mite picture. Here is a drawing of one--->

 

[Donmagicjuan]

Ok I defenitly don't have spider mites from seeing the picture of them, but I have Spiders! lol are they as bad as Spider mites? Im thinking worse bc the things I saw were godzilla spider mites, there are a ton of spiders in the area I noticed, im guessing that would have something to do with it. I mean im pretty sure how to fix the problem (With pest strips) but it scares the shit out of me when i see spiders going up and down on webs and shit on my plants

 

[Brian1975]

I would think it a good thing, unless they are storing their dead prey in your buds. Just a little added pest control.

 

[420-Grower07]

Man they look pretty big for the little party cups you have them in may be root bound.

 

[Donmagicjuan]

Heres an update on the pics, probably my last until another problem happens (Hopefully not). I figured it was just a one time thing, That was the only sign of spiders on the plants and I figured thats about it. Also I mentioned about the yellowing in my first post I think, You can see it in the top Pic at the bottom, anyone know what that is? remember I had root bound issues and they were a bit underwatered for about a week because of it. They were fed a good amount about an hour before this pic

 

[Brian1975]

They look pretty good to me. Make sure you don't let the leaves lie in the dirt. Not saying you do but the one pic looks like it.

 

[Donmagicjuan]

The plants have been good with the biggest about two feet now, and still in veg, a bunch of new nodes are staring to form slowly. I don't have pictures but I've noticed on a few plants that some have suffered heat stress.

It started with just one fan leaf on the smallest plant, but now it looks like it starting on the new leaves of two plants. The temps are about 75-85 during the day and 55-70 at night depending on each day. The plants ARE surrounded by a small stream, so the spot is very humid. Could humidity be stunting growth and/or causing stress?

The leaves with heat stress are folding up and pointing away from the sun , the most affected fan leaf is almost full brown now.
