two spotted spider mites and buds?

[thylacinelives]

P.H ?

I have been using ph 5.8 - 6.2 using ph pen,
Which reminds me maybe I need to check the calibration. Hmmm, got me thinking now. That would make a lot of sense as EVERYTHING, has been changed.

OFF to check calibration!!

Low temps and high humidity

Inadequate air circulation and extraction

Temp sits about 25c and humidity about 57%. according to my 2 hygrometers (I have 2 to double check) The only time the humidity increases for a bit is after watering.

Shit, shit, shit!! my ph pen was reading more nearly three points higher than it should so my 6.0 , is closer to 9.

How do I rectify the is issue quickly? and will my seedlings survive? They are looking pretty limp now.

Mate it aint 3 points out, it's like 300 points out
From 6 to 9 is huge
I would be flushing st away with like 6.5 or even 7
Then bring it down to 6.0 gradually

OK never had to flush in an instant like this. I usually just give ph water two weeks prior to harvest. Is it the same way? Just keep giving pure water with each feed or do I just keep pouring water through the plant until it runs clear? Will it make the seedling too wet as they are in 5 gal bag and only a few weeks old.

 

[afghan bob]

Yeah gotta be careful with seedlings
Never seen or heard of ph being out by that much
If it was up 2 me i would just bring back in2 range gradually
Lot more peeps on here that know more, but i wouldn't go from 9 to 6 in one go
Maybe give one flush now and then let dry out over coupla days
As u say they are big bags for sm seedlings so i'm not 100% on that
Oh yeah, get another ph pen

 

[thylacinelives]

Yep, that is what I'm concerned about too. I will see if anyone else chimes in with some advice and go from there.

Thank you so much for mentioning ph. It never even crossed my mind that that was the issue.
Poor babies :-( I have been pumping them with nutes, and spraying to try and rectify the issue. No wonder they were invaded by the mites, they had no health to fight them off!

Take note everyone, check your pens or you will regret it.!!!

There is a reason some of us old cunts don't use the LED pen PH testers, they're fucked
Use the liquid PH tester, piss yellow is the go

I'd be watering with the correct PH (6) don't worry about bringing it down gradually, it will take a while anyway, unless you flush the fuck out of it

No idea what grow medium your running, advice might be differant if I did lol

Sorry, thought I mentioned it in earlier post when I got all new stuff. Anyway I use coco/perlite mix in 5 gal grow bags. Appreciate any advice you have. Thanls

 

[Pedro de pacas]

Water with the correct PH, they will come good, coco/perlite is fairly straight forward

 

[thylacinelives]

Thanks Pedro!

 

[afghan bob]

There u go buddy, unquauntumfiable advice from the top
Pedro can be quite informative at opportune times
Ledgend
Hope u sort it all out and well on ure way

Coco perlite. There's your problem
Jokes... Probably too highly concentrated Neem solution. Try predatory insects and drop the oil sprays... Only spray with aloe to minimise harm to your beneficials

 

[Donothing-garden]

Also, mulch on an inert grow media like coco is asking for pests and pathogens.

 

[Sedge]

Coco isn’t inert

 

[Sedge]

But it is shit.

 

[Donothing-garden]

But it is shit.

How is it not inert? Any RHP Coco here is just sterilised and rinsed etc...

 

[Donothing-garden]

Coco substrate is a hydroponic medium.

 

[Sedge]

If it goes through Cation Exchange how can it be called Inert. .?

 

[Donothing-garden]

For the most part its considered largely inert. It does contain potassium and sulfur etc.
