Is this Over ferilizing, PH or Both (with pics)

[Blue Blazer]

I've read and read and read but cannot narrow down

Vegging White Widow in coir under cfl's 24hrs. Feeding with A+B as per Canna instructions every other watering (which is 2/3 days between waterings)
I started off without Perlite but have added it after transplanting pots. The problems started before the transplant. My runoff is 6.0. I flushed yesterday with 5.5 PH thinking it was over fertilized.
My temps are also 60 -65 constant.

Many thanks for your time.

To cold, try to keep them mid 70's
Humidity to high if you can, try it to keep it 45-55%

If you already flushed and transplanted them well snap off damage leaves and keep an eye for the next 5 days.

It doesn't look very green for being over fert. I see alot of purple stems. like a phosphorus defiencey
pH Range for CoCo Coir is 5.4 - 6.2
Good Link for CoCo Coir https://www.rollitup.org/do-yourself/48979-idiots-guide-coco-coir-5.html

IMO- I don't really agree with the whole check my run off to tell me what my mediums pH is.

Good Luck on Your Grow.

Thanks peeps. I've just insulated the tent from the outside and im gonna remove the affected fan leaves.

Great forum

The purple stems are from lack of phosphorus, but its not that it doesn't have any, its just being locked out by the cold. I have colder-than-average day time and night time grow room temps and almost all of my plants have very red petioles.

If 60-65 are your daytime and nighttime temps, then I'd say that's your problem. Plants grow very little to none @60 degrees and under, especially if its that cold for 24 hours. Locks out all kinds of stuff.

Yeah, get your temps up in the lights on period to around 72 deg f.

I just spotted a similar looking deficiency on my one month old for the first time yesterday. I'm growing outdoors and lately the nights have been getting colder than usual so that's what I'm thinking but I want some opinions. Any at all would help! Thanks

You aren't doing anything crazy wrong man other than bump up them temps. You're plants looks pretty good for the size and all, long way ahead.

 

[lime73]

they are cold and hungry...and do Not remove any leaves!

i'd be careful about over watering till it grows into that pot as well.

Quick update. I've added another 30 watt cfl and the tent temp is a nice and cosy 74 degrees. She looks much more healthier today already.
I also have a Lemon Kush in the same space whose 1 week younger and she hasn't shown any of the WW's signs so all looks good.
Thanks again.

 

[Blue Blazer]

The WW has continued to show problems while the LK thrives so it wasn't temperature. Come to think of it, I started the WW with non ph'd water, no perlite and my water is 7.0. My guess is phosporus deficiency as predicted by topfuel

Another update.

I flushed again with ph'd water a few days ago and then fed with half nutes yesterday and she looks a picture of health. Had to remove a few of the damaged leaves though.

Also had the confidence to fim her and i have a T5 on its way.

This is a damn addicting hobby. Well chuffed

Thanks buddy. Your first grow really is a learning experience isn't it?
I think the best advice i've read is to understand the plant then try to diagnose its problems yourself.
Im also experimenting with some LST on the lemon kush I have growing as well and we'll see how that goes.

Cheers

your welcome

really its a learning experience, the tricky part is learning how to read the plant/s, they can tell us allot about what they like, or don't like, just by the way they react. ....and by the looks of things she is bouncing back fast!

yes they are very resilient, but they can only take so much, for so long...before it starts going down hill. I'm happy to see the improvement in such a short time!

so what do you think she saying to you now?

...............imo i think...."ahhh thats sooo much better"...

Aahaaaaaaa

Aside from your issue, leave your leaves on! Let it suck the rest of the nutrients that it can out of it before you take it off, unless you can justify the increased light penetration in your canopy.

Can you explain this a bit better please.
I was under the impression you didn't want the plant to waste energy on virtually dead leaves so it could use the energy elsewhere. The leaves were curled and mostly yellow when I removed them and it only seemed to help the rest of the plant.
Is it a stress issue?

Thanks
