I'm an idiot-- yellowing/dying leaves- need advice

[FreeLivin]

Quick update, nothings changed, HA, ok so I gave her another good feeding and periodically sprayed her with an ammonia spay, nothing seems to help, the leaves keep curling, turning brown and drying out. I checked the ph at runoff and it was kinda low, 6.1 after I gave her a 6.4, I'm going to flush her today and see if that helps. but she just started to flower a couple weeks ago, then seems like they got burnt and nothings changed since for the most part, so I don't think it's the life cycle but I could be wrong, it's probably a combo of things. Well, any more suggestions or advice I'd really appreciate it, thanks again.

Another quick update, I flushed the NL two days ago with a lil over a gal of RO water with PH of 6.4, my run off was about 6.1 again, waited to see any response today and more damage, I checked what was left of the run off and it was at 6.7, weird, I cleaned it up and just gave it another flush-kinda, used reg tap water this time cause I'm out of RO water and set it's PH to 6.5, and checked the run off, it was 5.9, WTF, ok, so I checked the PH pen and it seemed ok, ran another half gal through her at 6.6 and same, then ran it at 7.0 and got 6.1 again at run off. Should I go higher like to 7.3 and check it, I know it's a lot of water the past couple of days (using h202 with water against recommendations of killing microbes but I need the roots the breath with all this water) but I think this is a major issue. I'm going to give it one more around 7.3 or so and see what happens, Hope I don't regret this but it's dying way to quick, so soon it won't matter.

Hmm??? Ok 1-22-14 Well I'm at a loss, I've just spent the last couple hours flushing the shit out of her with tap water which says it has a ph of about 9, I finally got a reading of 6.3 at runoff and then gave her a small feeding of ph water at 6.7 with 1 tbs of nutes, checked and ph runoff was back to 6.0, I wanna strangle something, why such fluctuations, I have a shitty PH pen but every time I check the tap it's consistent and seems to be close in color when I check it with the dye, grr so aggravating.

1-24-14 Not much of a change, I'm not sure why but the PH is chaotic, I prob flushed with 9gal and it's still not stabilizing. I Know she's wet ( hopefully not too bad since I used h202, against recommendations) but I'm almost inclined to give her one more feeding at 9.5 ( 9.5 because a fellow member with a similar issue has been feeding at 9.5 to get runoff at 6.5 and has been working for him ) with a lil nutes since I'm sure a lot if not most washed out. Just hate to see her like this. I don't have any kind of root stim or anything, no $ right now since I lost my job, so if anyone knows of any inexpensive or readily available ways to help the roots I'd appreciate it. Thanks

This is very similar to my problem, but 1000% worse. I feel for you man. I only use 9.5 ph water because my runoff is 3.5 when using 6.5 water, so you don't want to go that high. You've run a lot of water through her already, so she needs a couple days to relax I think, but you could up the ph incrementally, to say 8 and see what you get. At this late in the stage I dunno man... on the positive side, you do have 2 nice girls looking ready to get chopped, so 2 outta 3 ain't bad. At day 70 you don't have much time. Interested in what others have to say to save your girl.

When you feed do you mix your nutes then ph the nutrient solution? or do you ph then add nutes?

Also you might try to sprinkle Baking soda on your soil, maybe a few table spoons spread out over the top, then water through it......

Man, I've fought those pH battles myself and it can drive you insane. Hard as it may be to see your girl struggling, my suggestion would be to take a step back for a couple of days and let the soil dry out & then start fresh with checking the pH. I've had a few plants do this over the years and there wasn't much to do but ride it out. But I will say that I've had some pH stunted girls eat up all their fan leaves & then have the buds go frosty and dense right at the very end, so don't give up hope. Green karma sent your way...

Top that soil with a few tablespoons of dolomite lime and water it, if your PH is getting all out of whack like that then you need to buffer your soil. Also I saw you post that you fed nutrients and didn't see any improvement. What improvement are you looking for? Those yellow leaves aren't going to turn green again, they are damaged and will turn brown die and fall off, the plant won't repair them. Once you get your PH stable the new growth will be nice and green.

When I used OF in the past I added dolomite lime to it before I used it. Topping the soil with lime and watering it will help buffer your soil to the correct level

Hey GoAuto6, I Ph the water first then Ph the solution after nutes too, prob unnecessary but I like to see how much one thing or another might affect it.

Hey Andy thanks for the reply, I'm letting her dry out after giving her a feeding of 9.5 with small amount of nutes after that crazy flush, still got 6.2 runoff, crazy, don't understand why.

Hey MindzEye, thanks for the reply, Improvements I was looking for were no new dead or dying leaves after I removed all the others, prob shouldn't have but I needed to see if there was any success since there were so many I couldn't keep track. I haven't used the dolomite yet, supposedly the ffof has a ph of 6.5 to start and my feedings for most part have been on point, but somethings thrown her way out, wish I had an idea of the cause or causes. I will look into getting some, for now I guess I'm just gonna give her a high ph feeding again next time and hope for the best.


Thanks everyone for your insight and help.

Ok, update, I purchased some dolomite and put a couple tbs on the soil and watered her with RO water with a mid to low 7 PH, guess I should have done it with the 6.5, I checked runoff and it was good at 6.3, went to bed - woke up and it was 7.1 and 5 hours later it was 7.5, haven't checked since, so now I'm not sure what to do but wait a day and give her a watering at 6.5 and see if it corrects itself. Not happy, kinda was relying on this one since the other two are so small, she seemed to have potential. Oh well..

It will take a week or so to buffer out I'd use 6.0 as your in.... did I show you this.

Rough Calculation Guide:

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
