PH issue?

Hi everyone this is my first post here so sorry if it’s in the wrong place,
I have grown many times outdoors and have made the move to indoor for my new area is very cold. I have never come across problems like this, top leaves are curving sideways and a lot of yellowing of inside and outside of individuals leaves with top and bottom leaves going crispy and yellow also.
I have tried raising pH, flushing nutrients and adding nutrients but it seems to be getting worse. Can anyone attempt to shed some insight on this as I am compeletely stumped as it’s been so long that there appear to be multiple problems now. Any help would be amazing , cheers

Nute lockout. From too much fertilizer at least. Are you checking feed pH? And why did you raise the pH?

Thanks for your quick reply bro. Yes the feed pH is fine and I raised pH because the run off was slightly alkaline (7.something)

Hi man.

Im just gonna say it bluntly.
Please dont take offense.

1. Its too cold. Get it warmer.
2. Its too cold. Stop feeding too much.
3. Its too cold. Plant metabolisms slowdown.
4. Its too cold. Stays wet for too long.
5. Its too cold. Certain nutrients are unavailable when roots are too cold.
6. Its too cold.

Warm it up op.
Any temperature below 18'C starts becoming harmful for MJ.

Warm it up.
Dry it right out.
Big drink plain water.
Then resume as normal.

Good luck op.

You raised the PH because it was alkaline???

Cheers for the reply bro! Tim198 my temps never drop below 20 degrees however which was my average outdoor temps last year :/

Yea sorry chunky stool I’m studying chemistry atm and we use POH for alkaline and Ph just for acid. so I was meaning I raised the power of hydronium in the soil. Adding acid to the watering scheme. Cheers

Well id have 20'C as your night temps. 20 is a bare minimum imo. Unless finishing flower.
Should be a good 25'C during the day.

Im confused.
You say your temperatures are way too cold.
Then they're ok.
Which is it?
Whats the minimum temperature its been, in your space? It shouldnt be any less than 20'C.
Trace nutrients lockup, and thats what it looks like to me. Zinc, Molybdenum etc, etc.

What is the ph of your media?
The important part.....

What is the ph of your medium?

Sorry for the confusion man, I meant outdoor temps where I’m living at the moment are too cold which is why I switched to indoor, the coldest my plants get is 18-20 and the light phase temps are 26.
The pH of my medium is 7.something (crude ph measuring device) and I’m guessing when you say media that is the liquid I put in? Which is pH 6

They were completely fine for the first 4 weeks and then in the last week or so it all went to crap with the only change I made was lowering the lights but raising them back up didn’t fix the issue

Its either.

1. Too cold (if its fine. It is fine)

2. Too wet. Seems likely.

3. Ph out of whack. Definitely likely.

4. Overfed / fried. Definitely likely.

Three possibilities it could probably be.
Maybe a mixture of all three.

You stiil havn't stated your medium.
Soil?
Coco?
Peat?
Perlite?
Hydroton?
etc.

You still havnt stated your NPK% either.

Help us, help YOU.

Would you withhold vital information from a surgeon, if they were about to operate?

Give us info.

Stop dicking us around.

If you dont know. Just say it.
Its all good.
Its info we need.

Do you want people to help you?
Or not?

Yes man I don’t know, it’s my first indoor Grow, I’m completely stumped Tis why I asked for your help. But now I know what you need to hear so thank you for telling me bro
-It’s in soil with about 1/4 perlite
-NPK is 10-10-2 organic guano fertiliserD

Not sure why you think it’s too wet but I water when the top gets dry, I have been growing outdoor for awhile which has never given this problem thanks for helping me man

Hey man.
Im sorry too
<3

I can be pretty blunt at times.
Just as long as it helps


I personally think you should dry it out some.
Then give it the biggest drink of plain water its had.
Dry it a second time.

Then resume light feeding.
Once a week or so.
If that in my opinion.

Im concerned for your k%
The plants usually need slightly more pk than N. Usually a fairly even PK ratio too.
Especially seing your soil is rich already.

I'm glad you found it helpful friend.

Good luck.

Ok thanks I’ll give that a go however you have concerned me by saying “for this stage of flower” as it is still in veg stage. With my last grows I started on farm soil and just compost the dead plants from last season into the next seasons patch. What would be the ideal NPK for veg? A friend of mine recommended the current one I am on as he used it for tomatoes. Something like 3-1-1? Cheers man

Haha.
Lol
Thanks i'll fix my post.
Between two threads. I didnt check which plant to which thread sorry.


Everything still stands though.

Other OP is nearly halfway into bloom.

With very similar symptoms.
Might be worth browsing the thread.
I referenced some information, i think you'll find helpful.

Sorry i got you two confused.

Every piece of advice still stands though.
You will need to up your K somehow too.

Thanks for correcting me.

Good luck.

Ok sweet I’ll give it a read, thanks for your help man I’ll post a pic here once they are all nice and healthy grateful for the minds on this site

Oh, I get it. pH never had any real meaning in it's letters but knowing that, it makes sense.

This is why I hate fancy bottle regimens. They really make you dig for that basic info
