Need help with my LED grow

[ridoo]

Hi all,
i got some issue in my flower room, space is 60cm x 90cm

it's lighted by a panel of 300w and a ufo-like spot of 145w

medium is coco

Ph is 5.8

for nuts I can give canna coco, or the floranova bloom (head formula)..

but my plants dont look well, some leaf looks like burned and the flowers dont get big... I mean i grow a lot under hps and get much bigger cola under 250w hps

I would like direction about nuts, i prepare my solution in a 1 us gallon tank

in that watter quantity what would you use as nuts in quantity in ml ?

i tried to use as said by canna but it dont works that much
i switch with floranova and epson salt (head form.) and it dont look to go better

my panel dont work all time together for avoid heat, one start at 7.30am till 2.30pm (he looks more blue), the second start at 12.30 till 7.30pm (he looks more red), they work together only 2 hours in middle (kind of top sunlight in the middle of the day...)

i have plenty of vent system, movers, extraction, whatever...

so i guess they are not to hot nor burned, dunno really, but it's kind of nuts issue i cant figure out

(sorry the gallery dont work right now so i cant upload pictures yet)

my veg room under CFL is just great, i clone a lot, grow nice plants and so on, there i use canna coco and it goes all very well

so, before i can send some pictures, how much nuts would you mix in that 1 us gallon watter tank ? I feed them by hand

Looks as if your ph is way off. I would flush the plant with a light feeding maybe 2mil of canna that would be the first place I would start.

Also one shot says and he is one of the best led growers on here that you should always add cal/mg to your feeding regimen because when growing under LEDs plants tend to need more cal/mg.

But I would flush your coco that would be the first step I would take. Also in flower I think you are supposed to bring your ph up a little like around the 6.0 ph area in flower. But first things first flush with a ph'd light feeding and that should straighten out your issues.

one of my past grow under 250w hps, this was a dumb F1 home made cross, in coco, 3L containers

I guess my current full crop under ??w of LEDs is not goin to be as big as this single plant...

hum
good idea

but i read around that plants under LEDs need more food that others under hps...

and i use 1gr of pure epsom salt in my watering with floranova bloom, but not with canna... maybe they suffer the need of this missing calmag

do you think it can be good to use some hyox 35% in that flush ? or with nuts ?

I read it can be good till 1.8ml / Liter but dont know if it still right under LEDs...

Thanks for helping !!

The led issue could be a couple things

Whose led panel, and which one?

Monochrome panels typically avoid the 500-600nm range, which plants need too. without deficiencies can/will occur

Buy a couple Cree NW (Daylight) floodlights at Home Depot and hang them in there to whiten things up.

Dabbling in mixing nutes when you lack the skillz is dangerous. I recommend Hydroponic Research V+B- they have soil formula too

I got one panel and one ufo spot, the ufo have plenty of colors from blue to red, the panel looks... pink... dunno the tech spec as i get them both for free from a bored friend..

the point is there is lots of light in that closet and i'm not gonna put a new one because of heat and available surface and so on..

It have to grow with that ones or next year those LEDs will go trash and i simply get back to my cooltubed 250w hps...

Hey buddy that is your problem right there. The part where u said under LEDs need a lot of food. That is not true at all in coco u have to be careful of salt build up. Also In coco you should feed lightly.

Also I think to much mag locks out potassium I think? I can't remember what to much mag will lock out.

I also grow under LEDs and if I am not constantly giving them a light feeding of cal/mg throughout they will definitley show a cal defiency.

Also what pet flora recommended is good stuff I have that food you can actually go to there website and pay I forgot like 5 or 10 bucks I think it's five for a free nice size sample. They also have a dirty formula or r/o formula depending on if you have hard water or good water. Plus those nutrients has everything in them even silica it is truly a all in one nutrient program. Good shit and if u mix by there directions your ph is usually spot on for what u need.

Ok, see what you mean

I'm gonna gently flush them with light soup and epsom salt

then feed them lighter than before and add epsom salt all wattering, and see if things goes better in next 4 or 5 day... it goes fast..

thanks for all clues

Can someone report to admins that we cannot search the forum with "LED" or "led" because it's to short.... ?

It make research very annoying throught dozens of topics from "grow diaries" to "coco grow" to "LED grow light" sub-sections... then it make search kind of.. useless tool

And why is there no "Grow diaries" section in LED section ? it could make it very faster to find informations into other growers experiences...

By the way, if you are an : hand watering coco medium LED grower, please share your tips

thanks a lot
cheers

?

Once you open LED Grow Lights, just scroll through the thread titles

That said, IC is lacking in LED threads. My own get very little interest. One is 2 Custom UFO 90s, the other led v hot5

See my sig for links

Hi all,
PetFlora, what i mean is when using the advanced search tool we cannot search forum section with "led" keyword because it's to short...

So scrolling all sub sections for find diaries or journals or infos about peoples growing with led in coco is not that easy...

___

So, i started to water with new solution, 1us gall water, 5ml floranova bloom, 1gr epsom salt, ph 6.0

___

there some pictures with better details and white balanced for give more informations about the issue

 

[Mikenite69]

Looks like you are expierencing a p and k lockout. It's either because your PH is way out of range or a improper balance of nutrients In the coco.

Did you atleast try to flush your plants with a ph corrected light solution? Even after you flush you still want to maintain a light solution until u see them bounce back. But the key in coco and With LEDs u don't have to water/feed everyday because with LEDs the plants aren't drinking as much as they would under a hps or Mh. When I grow in coco I usually will feed let them go a day or 2 depending on how wet the coco still is then water/feed again.

I mean there not showing any signs of nute burn so my guess would be either a lockout of p and k or your ph is out of range but I am gonna say its most likely a lockout.

 

[ridoo]

My ph is currently 6.0
I tested my probe some days ago and buffer it on a weekly basis for being sure the soup is really at right ph

You gave me good info about time between waterings...

With hps i used to give water/food everyday...

do you think that 5ml of floranova bloom is still not light enough for a flush ?

I'm gonna let the coco dry a little, and put one day between each feedings, not to much, and then water with 4ml floranova bloom and epsom salt and cannazym at Ph 6.0

hope its gonna be ok, hope i can get something at all from those suffering flowers...

i have plenty of cuttings awaiting in veg room... i'd like to find the good way to make those ones healthier in bloom than the plants actually blooming... poor babes...

100% m8 too much "light food" from the led [ideal light spectrums for the plants is the reason] grow them under hps/mh until ya have a good root system or there 2' tall then re introduce the led

you probably know this going by the date now...But THATS the reason
happened to me and dont try n fix em/hope they will regain normal growth i went 6 wks + hoping for this but not a chance they stay like they are! so a waste of time n money

[..wonder if they'd right themselves after 2months +!???
again tho not good to see and to have that every time ya see em nahhh!]

 

[SPG.]

Totally not PH .my initial thought too.. but soon learnt the above^

How you doing now i expect you know this with reasearch.. spoke/witnessed this alot on the uk forum... now we all know ..expect so anyhow
