Day 1 of 6 week flower leaf problem

[GLN]

Hi guys this is my first grow and iv had few problems which sorted out now this one.

So 2 week ago I kind of burnt a few leafs high temps that settles down back to normal apart from the odd brown crusty leaf.

I then changed my light too a cool hood and hay presto temps down to a consistent 26degree night temps 18. First Picture is of the burnt issue I had nothing to do with this new one just wanted to let yall know so u know that is where the really bad leads come in.

So my problem lies with yellow leafs all over the place, last night was not too bad today really bad in my eyes and I’m scared this crop may not be able to finish.
Gonna post some pictures up as it stands I feed 1 ml per 1 litre of 6.2 pH water I give all 6 plants 2 litres each till run off and then leave till top lair dry probs 2 maybe 3 days if it’s cold here.i use 10ltr pots with coco perlite mix.

Few more here under neither don’t look yellow odd one maybe

You didn't just miss watering on time?

 

[whitebb2727]

What nutes are you using?

 

[whitebb2727]

You also might need to water more often. It's hard to over water in coco.

 

[GLN]

Hi guys no I feed to run off then let dry out for 2 days so say I feed Monday night soon as light comes on they will dry out to feed again by Wednesday night.

Remo nute kit buddy

I think if I water every day I may have run off every day but can try.

A couple things. First when they get late in flower they will start needing more water. Water more. You don't have to feed every watering. Feed on the days you were. On the days you use plain water you don't need as much run off. The only reason you want run off with nutes is to prevent salt build up.

Next. From that chart it's not showing any veg formula. Is there any nitrogen in any of the bottles listed for flower?

A lot of flower nutrients are lacking N. N is still needed in flower. Cannabis burns through a lot of N during the stretch. It's why you see a lot of yellow plants mid to late flower.

Either run the veg chart until stretch is done or add some grow formula back in during flower.

I have not checked for it buddy been a while feed kit I took the shops advice and just been giving this all way through.

I can go but some N nitrogen tomorrow if that’s gonna help them for another week till I get To flush what u recon buddy.

Ye I did stop adding that grow nutes end of veg 4 week as it states so maybe there is my problem if that is the one that contains the N

How would u guys recommend getting some colour back into my leafs bring them green again just been told week 6 of flower I’m at is a true 4 week really and I have 4 week left to grow these bleeders, so leafs need to last till then.
Few things on my mind....
Do I feed some veg nutes to get colour back.
Do I water more higher nutes I’m only feeding 1 ml per litre at the moment 6 plants 2 litres each every 2 days.
Do I need to flush for a few days then back to nutes.

You water all the way through to saturate the soil with water. Not to prevent salt buildup.

 

[GLN]

Thank you matey.
I flushed them last night and checked all my run off I put just 2 litres of tap water though them run off veried so pH was between 5.3 and 5.6 this is after 2 days since last feed, EC was 0.9 to 1.6 so got some difference here even tho I’m giving them all the same mix.

 

[GLN]

If iv got this right I need to make my root PH around 6.2 not what goes into my coco as this will be changed as I’m seeing. Ec levels what u guys recommend been told 1.2 by my grow shop but yall would be better help again I’d this what goes in or what at the roots.

Thanks guys

Just got this to help me

I grow coco myself too.

For starters.
Every single feed, or watering. You MUST have 15-30% waste runoff. At least once a day.
Or for small plants every other day.

Couple very important questions that haven't been asked.

WASTE RUNOFF
Whats the ph?
Whats the ec/ppm?

You are running hydro drain to waste, im assuming.

Get a reading of your waste.
I can almost guarantee you'll be shocked by the readings.
Post back with your waste results.

Pleae post the ph, and ppms of your feeding solution too.

Good luck OP

Hi buddy thanks.
I have only just bought my EC pen but last night I tested run off after I put straight water though them and as above my EC readings were 0.9 to 1.6 and pH were 5.3 to 5.8 between my 6 plants.

 

[GLN]

I’ll feed everyday from now for shore what iv Hurd and been reading I’m just new and dumb.
Also I use 10ltr pots sat in trays and run off waste just goes into them buddy.

No problem dude. Happy to help
If it were me in your shoes, i would -
Get that waste ec under 1.0
Get that waste ph to between 6 - 6.5.

It should start greening up a little.
Id be focusing on the waste ph most of all.
Imo thats a little low for bloom in coir.

Yeah thatll definitely help.
I water/feed myself everyday. You'd have more aeration than my coir as well. I dont use perlite.
So everyday shouldnt be a problem at all.
Make sure you always dispose of your waste quickly as well. Dont let the pots sit in their waste.

Good luck OP.

P.S
You're no dummy

There sat in it at the moment but I’m getting something to put the pots on ASAP or something that will suck the waste out of my trays.

I stupid lol so how would u go about Geri g all those levels in the right plc so I can start nutes again buddy.

I use a wet/dry vacuum, to suck up the waste from my trays. They're awesome!
One of the most useful things ive ever bought..

I always go by my waste.
I make sure my waste, is reading very close to what im feeding.
Both ec and ph.
Go by your waste with coir.

Best of luck OP.
