I'm having yellowing and drooping.....need help

I always make my ph 6.5 before giving it to my girls and that includes nutes as well. My soil runoff is always around 6. If it's a phosphorus def. what is there I can do for it? So am I way off when I said it could be a nitrogen deficiency?

6.5 and 6 I think that makes 5.5 for the soil
 
And sorry about the duplicate threads. I always do this from my phone and it gets whack sometimes
 
get your ph up, I'd flush with a solution of 7.0 for 1 x the pot size then hit it with a 6.7 watering with 10% run off and Check the ph of run off and re calculate.

[h=2]Rough Calculation Guide:[/h] Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

If you see the chart above at 5.5 in soil you are locking out a lot of needed nutrients......
 
5.5 would be too low in soil I believe. Someone will be along with the best way to correct.

No, not a nitrogen deficiency. Feeding at 6.5 and getting run off of 6 means your actual soil pH is somewhere around 5.5, which is too low and causing a nutrient lockout. Looking at the chart below you can see that at a pH of 5.5 not only are phosphorus and potassium unavailable to the plant, but also calcium and magnesium.

Tell us about the soil you are using. Did it contain any dolomite lime or have you added any? If not, you will need to add 1 tablespoon per gallon of soil mix to help raise your pH. It will take a couple of weeks for the lime to become effective so in the mean time, up the pH of your feeds to around 7.2 - 7.3. Keep checking your run off and and as you see the pH start to come up, lower the pH of your feeds until both are reading in the 6.3 - 6.5 range.
 
yeah ur gonna want to get that up as soon as possible if she startin to flower.need that phos for them big ass nugs
 
Sorry guys, I know I haven't gotten back to any of u in a few days and I haven't cared for my girls the way I normally do, my dad is battling cancer and doesn't have long. But I just went down to my room and now I'm completely baffled as to what's going on. I added tap water that I ph'ed to 6.7, and my runoff was 6.5. So therefore that makes my soil ph 6.3 correct? By looking at the chart it doesn't seem I'm locking out very many nutrients. I did just notice I have a bunch of red stems on 2 of the girls. Could this still be a phosphorus def? Or possibly something else? Do u guys recommend I flush em? And sorry muddy, no my soil didn't contain any dolomite and I haven't added any at this point.
 
If it was at 5.5 and now at 6.3 it will take more than 5 mins to notice. Its only been 2 days since it was 5.5 and you just gave a feed now.
 
I added tap water that I ph'ed to 6.7,

What is the ppm of your tap water? Mine is up in the 700-800 range. That caused my nutes to be locked out. You could switch to filtered (reverse osmosis) water found at those dispensing machines at the store, or sold in gallon jugs. That would eliminate variables like high ppm and chlorine (or chloramine which I've read won't dissipate with aeration).

Do you aerate your water? The ph of my water (tap and RO bought from a dispensing machine) rise significantly for a day or two of aeration. I think this means it will rise as it sets in the container for a day or two. Aeration gets that process (absorbing carbon from the air, creating carbonic acid?) out of the way. (Although, in your case, it sounds like ph drifting higher wouldn't be bad since you're fighting low ph.).
 
Whoa that was a whole lot of info that I've never read up on. How do I check the ppm of my water?
