Little Guidance Would Be Niceee

[Nugsy]

Another begginer grower in the cannabis area but experienced in gardening just not...indoors. I have a couple of plants in veg will post pics later. But right now I'm really wondering abt these lights because its only 2 theu are only 15w an my plants are all atleast 12.5in away, they aren't harming older plants but any seedlings are always doing strange things like they aren't really burnt but the leaves seem to get really crunchy an eventually yellow,brown and die.....Is this due to humidity?? Or soil deficiencies??? I'm growing in cheap organic mixed with compost manure peat pearlite and sand my ph is sum where around 5.9-6.3...help!!?please

Hey Bro.

Do you know what your current humidity and temperature is?

I've never used LED's, but from what you have said seems a little confusing. When you say your leaves are becoming yellow, brown, then die. Is the plants growth still progressing or is this happening to the whole plant or just the lower leaves would u say? If it is just the lower leaves but your plant is still growing and other leaves are a good green. Then this is just normal and a result of lower leaves not being able to get enough light and you can just pull em off.
Or do you mean your seedlings when they still only have 4-8 leaves. As this would be a bit strange.

If your humidity is much lower then 40% this can cause leaves to curl upwards and shrivel eventually dying. Would also cause them to yellow and die. I had this problem briefly but spotted the signs and increased the humidity which solved the problem straight away.

Hope i can help :-)

I think 12" should be fine unless you are using 3w or 5w diodes, then you would want 18". Maybe some epsom salt?

Hey Dank, I dont agree with your statement tellin dude that low humidity is gonna cause his leaves to curl and die. Cannabis can be grown in very low Rh levels. Yes I know that it isn't optimal, but it can be done. I live in a arid desert and its impossible for me to maintain and reasonable VPD or Rh. Been growing this way for years and have never had the issues you described. Take a look at the August POTM pic. That Cornbread was grown in 12-15% Rh. No curled or dead leaves on her. Not tryin to argue just sayn....... :)

From my own experience when my temps have been too high and my humidity mad low for too long, this has happened to me with certain strains. Not with all strain though, as i had several in the same room and not all had this reaction. So would not say this was at all a science, just know that this can be possible.

Obviously i dont know what your set up is, but do you grow at that RH all the time? Can you not buy a humidifier? Surely that doesnt work for all strains you have tried to grow?

 

[Nugsy]

Thanks guys for the help I'm going shoe yu what it looks like my big plants bottom leaves are yellow an dien but yes I know that should happen but on my seedlings....its not actually turning upwards its more curling downwards an starting to get like a greyish green an real crunchy like....I can't really describe it....Im sorry I do not knw my rh or my temp but my house temp is between 65-75F if I could guess rh I'd say maybe 30%-40% its not really humid in here at all and the seedlings are way more than 12in away more like 2-3 ft away from the direct light...they're on the floor. I really think its my humidity.... Could I just like mist them with a little h2o ?

1st pic is my whole setup
2nd is where my seedling is located
3rd is the damaged seedlings...still growing though
4my biggest plant probably 45-60 days from seed
5same plant
6believe it or not its older than the biggest plant jux not as big but its very leafy

All plants came frm bags of reg
Just tryna fully grasp the art of farming before I buy seeds from a seed bank

I'm a low budget guy and with the HID heat load and only relying on the homes central air and off course ventilation with the desert temps my ventilation runs nearly 100% of the time. It is a battle keeping Rh in balance, due to the fact that even with my humidifier the ventilation draws it right out of the room as quickly as it puts it in. Sort of chasing my own tail so to speak.

It's hard to try and get the right light with those-it can be done, but be careful how close the babies get to. I use Hortilux Powerveg, if you want to check out how my babies are.

Best of luck, and good vibes to ya. :)

Can I get somebody tips my plants not getting any taller just bushy

 

[Nugsy]

So I found that my seedling was infested at the roots :( And my older shorter plant turned out to be male but...that fast growing robust other turned out to to be a nice female!!! Fighting a few deficiencies an toxicities currently in flowering week 5-6 she's only about 29inches tall many small popcorn like Buds but its my first grow so I'm cool wit it...learning experience you know


Yo wonderberry...I'm not a pro by far but it looks like you might wanna move her a Lil further away from your lights She's lookin hella bushy though what's your strain? what's your set up?.....Try siting her a Lil further away make her stretch to the light you know

This is my first girl

This is my first girl

Pineapple chunk mate on a 400w light in a 1 x 1 cupboard white sheet around and a mirror on the floor feeding coco a + b rhysotonic n coco soil with my friends own root stimulator he created him self it's called dynamite I think that why it's so bushy the stem is really thick I feel it 1 litre a day the next day it's dry

 

[Nugsy]

Hella nice...wat are the ingredients if I may ask?

An I'm not rocket scientist but bro you need a lot more space than 1x1 mate that's mainly probably why she's so thick an fine Compact extra strong light will make her bush up this I knw. Now if you want her to stay that way cool then you are OK put her in flower (12/12) however if not give her more space and let her stretch up and out since you are at 1x1 try at least 3x3 but more suitable for a 4x4....that light can grow at least 10 plants in a 5x5 easily. Great choice of lighting thou mate I only used those bulbs cuz they seemed to be my best op at the time

 

[Wonderberry]

I have no room just a small cuboard I switched it to 12/12 this morning I feed it 4ml canna coco a 4ml canna coco b 4 ml rhizotonic the dynamite came already dialuted so not sure the strength but I use 60ml every 3 - 4 days I feed it nuted for 2 days every third day just water

Currently about 50cm tall it's in 15 litre pots

 

[Nugsy]

No man I think that was a bad idea you would probably wanna let it do some more stretching or at least a light trim or clone etc something to help the light penetrate an produce thick juick buds all the wat thru the main cola ....ass of now pittincg her in Flower she's only gonna grow a few more cm an get even more bushier with popcorn pike buds... Kinda like me but my girl stretched due to insufficient yet sufficient light sources so shes stretched but not an unhealthy stretch like a nice growth spurt...but you on other hand mate have extra good lights and you do want to increase yield?...correct?


My suggestion may be a little off but if you are wanting a really good stretch put her around UV lights or black lights.,..through my own experiences I've witnessed to UV rays effect on seedlings but however I've never seen it done on a letter scale plant but I do know UV rays give plants certain rays of light but not enough of the correct rays so it stretches towards the UV lights hoping for stronger bor abundent light.. so since cannabis is predominantly a short day plant(meaning most up take an growth occurs during night cylces)I suggest giving your plan a few hours if direct uv light while lights are out and observe...but imbnot a expert an this I'd not my plant an I would hate for your plant your plant to die on my incorrectly csculsted info
so don't do it .. Its just something I would experiment with myself

 

[Wonderberry]

Il wait and see the next few days if it stretches ive got my light 3 ft away so hopefully that should be ok if not il try wat you said for afew days thanks for different ideas

 

[Wonderberry]

Anyone know about super cropping bendinging the stems to created like a elbow supposed to help with increased yeild

 

[Nugsy]

Your girl could use a Lil super cropping lol Try taking a fee clones an top her off at a few nodes I can tell you now your yeilds already gonna b impressive. I would top her an take those tops an clone them. It will help light reach the bottom of the plant an make her stretch more so you could me able to super crop more easily. But you should probably do this before 12/12 or within first 2 weeks... You don't wanna stress her too much on the beginning of flower...real good chance of making a Hermie so be careful

 

[Nugsy]

I'm still amazed at how bushy she is mate.How much did that light cost ya? does it put out a lot of heat?
