Auto Stopped Flowering

Hi
Day 41 from seed
I had trouble with the girl on the right with too much Nitrogen & then a calmag deficiency. I flushed her & gave her 2ml of calmag on Tuesday & she recovered or so I thought. But now she has stopped flowering. Her sister is doing just fine.
Any thoughts?

Give her some times probably just a little stressed out.
Thanks for the reply.
I posted on a different forum & I just got a reply telling me feeding them water with just calmag can cause p k lockout. I did that on Tuesday to combat a ca/mag problem. They'll get a flush tonight when they wake up
Again Thanks!

one feed of cal mag shouldn't lock out p or k if it wasn't overtly strong unless your soil was heavily amended with dolomite previously. It takes quite a lot of magnesium to cause toxicity and calcium is used pretty rapidly by the plant. its immobile so it can't be moved around and will be pulled from the medium pretty quickly in a form that can be used immediately.

I wouldn't put it under anymore stress with flushes. If your worried about p/k locking out, flushing the p and k out the medium will do the same thing.

I'd just resume a stable routine and give her some time tbh. The only issue I see off the top of my head is that Cal-mag contains nitrogen, so if you are already heavy on nitro it can compound.

They don't look obviously toxic in any department so I wouldn't go chasing tails atm. most damage is done trying to correct an issue that hasn't fully manifested yet.

As it is, you could just have to different pheno's with different stretch/setting periods.

Oh man, I thought growing weed was kinda straight forward! :)
Again, appreciate you taking so much time to help.
They are both autoflowers
I fed her with just calmag on Tuesday about 30min before she went asleep as I thought (wrongly) it was better to give her something to keep her going. That night I fed them both 4liters of water with 16ml of PH Perfect Grow Micro & Bloom. With 8ml of Big Bud, Carboload & AN Cal/mag Xtra.
I'm a new grower, so I've been getting as much information as possible. I feed them both every 2 days as needed checking their weight & I've been told to use the feed water water schedule & others have said feed feed water. I'm using the latter since Tuesday as I had other problems with a little Nitrogen toxicity at the end of veg & I flushed them. Their run off is about 12% & it's 6.5. They are due to get a water only feed tonight when they wake up
 

keep it real.

Growing is straight forward, you just need to find what works for you!! Overall plants look very good for 41 days old! I wouldn’t make any huge changes.

They still have some stretching to do, those are going to be some big girls!
It can be difficult with autos because they flower when they are ready and you have no control over it. One might grow to be a monster and the other might me more compact. Feeding will also be different from pheno to pheno.

growing can be as complicated or as simple as you make it at the end of the day. For example, this run will receive over 12-14 weeks nothing bar yard dirt/perlite as medium with 2 tbsp slow release mixed in at potting. No mixing anything up, no fancy mediums, no ph monitoring. I got caught up mixing a large repertoire of additives and measuring parameters far too often when I started.

You seem to have done well regardless, but it could be easier with a base fertilizer the whole run through when starting out. They provide everything a plant will need unless a glaring deficiency pops up. It's always hard to figure out what the issues are when you are adding three or four items to the mix, and then adding another supplement to counteract previous supplements.

Hello? Anyone?
Second girl has stopped growing. Cant find an answer online, just people with the same question.
Fed them 4 liters of plain water last night. Run off was 6.5.
Should I flush again or just dump them & start again?
Anyone out there who has had this problem & fixed it?

Stop checking runoff - it is worthless
Stop throwing CAL/MAG at it ( it’s NOT” the fix all “ )
Stop feeding every 2 days - plants feed when it wants to feed
Stop for love of god flushing - all you are doing is stress it , plus leaching the medium , plus upsetting the biome in medium.
Stop overthinking autos.

You literally can use a bagged medium , tap water and that’s it …… for weeks. Then when some exhaustion happens to mix , top dress more and water that in. It recharges the base medium and happily feeds the same nute amounts it is already accustomed to. No extra bottles - No complicated nute lines - No bullshit Reddit recs or stupid hydro shop guy . They are literally plug and play.

If flowering stopped for real ….. 2 things either happened .. you stunted , stalled it with the back and forth of nutes / flushing / etc.
or strain is weak sauce.
Autos can stunt and just stop from many stressors ( autos used to be worse - they stressed if you looked at them wrong )
But the possibilities exist since all they want to do is grow and bloom … they don’t spend time on repairs or drama.

I would only water it ( only as needed ) keeping light cycle as static ( 18/6 or whatever ) - give it 2 weeks .
If nothing happens - flip it 12/12 to try to force flower - if nothing …. Then toss it.

Thank you for the detailed info.
But I have been getting so much conflicting info. I talked to advanced nutrients support & they told me to flush when I thought I had Nitrogen toxicity at the end of veg. Then on another forum others told me not to!!
I was told on a different forum I had a magnisium deficiency problem & to buy calmag. I live in a very hard water area so didn't think I'd need it. I've only used it once last Tuesday, after which the problem stopped, but so did growth.
As for feeding, I've been told to feed water water, feed feed water. Feed when the pots feel 3/4 empty & never let them get totally dry as you can get pockets of air. To check the runoff & you say not too. Honestly I mean no offense, I appreciate you taking the time to help. But
I've searched online before I started so I wouldnt have to ask these idiot questions or have these problems & tbh, I couldnt find 2 "reputable" sources to give me the same answer to the same question!!
I'm just venting now so I'll stfu.

Again, thanks for taking so much time to help me out. It's much appreciated!!

I feel you. I haven't been growing that long and so many different answers to the same question is really frustrating. I've found myself staying away from the dogmatic, authority type of advice and focusing on advice that is presented in positive and enlightening ways. That's just me.
