Stopped Flowering

[Kilbarrog]

Hi
Day 41 from breaking soil.
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?

Looks good to me. What medium and what else are you feeding? If soil, careful with flushing and CalMag…. Especially using CalMag water on its own with nothing else… that can lead to lockout of P-K which is essential for flowering.

Are they auto's ? Are you feeding bloom nutes and what is the npk of your nutes.















Are they auto's





























































Are they autos?

Thanks for the help tronN00dles. I think you hit the nail square on the head!!
"Especially using CalMag water on its own with nothing else… that can lead to lockout of P-K which is essential for flowering."
I gave her a liter of water with just 2ml of AN Calmag Xtra on Tuesday.
I'm feeding them each 4 liters of water with 16ml of PH Perfect Grow Micro & Bloom. With 8ml of Big Bud &, Carboload every 2 days as needed.
I have been given lots of good advice here & I was advised to do a feed water water schedule. But I've decided to do a feed feed water schedule. So I planned to give them just water when they wake up later.

They are Lemon AK Autos. I think tronN00dles has solved my problem

What is your grow medium, soil, coco ??? I am assuming soil, then stick with water, water, nutes schedule, I only add nutes once a week in soil. Soil needs far less nutes than coco(what AN grow micro bloom was designed for) soil holds onto nutes while coco does not!

I'm using BioBizz Light Mix in 11 liter pots. I'm watering them to about 12% run off & that's ph 6.5
I started counting flowering as the 30th of August. I have only started the feed feed water schedule since last Tuesday because of the problems I'd been having & I thought I knew more than I did!! 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 her 4liters of water with 16ml of PH Perfect Grow Micro & Bloom. With 8ml (I said 16ml in my original post. It was 16ml in 8 liters of water for both girls) of Big Bud, Carboload & AN Cal/mag Xtra. She seemed to love it......
Fed them both the same but without calmag on Thursday & again, they seemed to love it. I had planned to feed them just water tonight when they wake up

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?

Those plants look too good to be flushing or dumping. Steady for the course pal, you're doing a good job. What do you mean the plant has stopped growing? Again, the pics all look fine. Veg growth is stopping and buds will start bulking up over the next few weeks.

Play around with the feed-water vs. feed-water-water vs. feed-feed-water, etc. Every grow has different phenos and environments so there is no one-stop solution. The best you can do is experiment and learn. Whatever you're doing appears to be working so don't sweat it.

The main thing with liquid nutrients is to keep your N-P-K-Ca-Mg ratios "balanced", i.e., pick a feedchart and stick to the ratios and just play around with the concentration/dilution. Autos like ppm's around 500-650ppm, so if a feedchart at full strength is 1200ppm, aim for 50% concentration and go from there.

I'll also add that this whole ppm/pH/run-off business is better suited for soilless mediums imo, like peat/perlite or coco/perlite. That being said, I've had success with this style of growing with soil as well.
