New Grower Autos stopped flowering?

[JJ05]

I am unsure if I am being paranoid or not but it seems my autos have completely quit growing/flowering. I'm a few days into week 7 and I have not noticed ANY pistols changing really. I cant for the life of me get my pH down past 6.8, its driving me nuts. Could this cause the plant to stop flowering?

give them a few days--usually they seem to quit budding then 3 or 4 days later you start finding new growth in the buds-- new white hairs---if she aint brown and drying up she is still growing--give her alittle more time.whats your setup--lights,ferts,etc?

Little more info or some representative pics would help ...... If you can't get your ph below 6.8, have you ruled out a bad tester?

They aer outdoors, ferts I used were FD's feed sched. I started them on pure pH close to week 7, prepping for harvest so I am getting rid of all the potential salt build up. I noticed when I last watered them with just pure pH water I had a run off of 4 possibly lower. I think its due to the salt in the ferts? Anywhoo heres my girls. The first 2 pics are of my Dutch Passion Auto Blueberry. The second pic is of my Pakistan Ryders. I got 2 different phenos. One runt and one tall one lol. The third pic is of my G13 Labs Pineapple Express. The last pic is of my purple jem. SHe has SUCH NICE COLORS!!!!!!

I have a control wizard accurate 8. I hope its not a bad pH meter.

You could add some powdered sulfur to lower the pH. This close to the end I wouldn't be too concerned about it. While 6.8 is a bit high, it's not too bad. Looking at your plants I expect you'll need to start flushing soon anyway. If you do feed them again, just drop the pH of the feed down to around 6.

I doubt there is a problem with your Accurate 8. When you check your pH with it, do you leave it for 10 minutes as they instruct? It takes that long to get a stable reading. Also, take 3 readings per pot, all in different spots, and average them out. I sometimes see as much as .2 or .3 difference between them. Since you have the soil probe there is really no reason to check run off. The soil readings are more accurate.

accurate 8 is a good one.... double check against something else... drops... litmus, another meter... something...

sounds and looks like a ph issue

Thanks guys. Yes Muddy I do leave my pH meter in the soil for 10-15minutes before I check ( I usually put it in and do a beer run LOL) Could the 6.8 pH stop the flowering? I will not be feeding anymore. Just pH water...unless you guys think I should feed one more time???

Looking at your pictures it looks like the fan leaves are just starting to yellow, so I'd say you have about 3 weeks left. That's time for one more feeding if you want. By the time the pots dry out again you'll still have a good 2 weeks left to flush. The plants use more P and K to produce flowers and at 6.8 it's not locked out, so I don't think that's the issue. The last 2-3 weeks the buds usually just fatten up as they draw on the stored energy in the fan leaves.

Thanks Muddy! I am looking forward to harvest . I had yellowing for about a week before this. However not too bad. I recall posting a thread about it then I flushed when you gave me the heads up to do so.
