I need insight with PH levels

[spunk]

So,I have been keeping a PH level of 6.7 and have had major problems.I took it down to 6.2 on PH level and little change. I'm in pro mix and I would just like to know what a solid PH level is for soil AND pro mix along with your reason.

I think I'm over looking things and need to find a PH I can work with and put a end to this madness.

6.3-6.8 is said to be ideal for soil, any and every soil. My soil however regulates itself to 7.5 and my plants don't seem to mind, happy frog. I'm always using ph down with each water and or feed, 15ml per gal. Sounds nuts I know but it's been working for me so far. At this point, I'm only checking soil ph, I don't even check water (kinda afraid to). I just drop 13-15ml of ph down per gal and that's my sweet spot. This is just what works for me and I don't recommend it but if I didn't try different ph levels, I wouldn't have found where my plants do best. Funny thing is that even with that much ph down, the soil only fluctuates down 1.0. 12 hours after watering, the ph is back up to 7.5 and will stay there until the next watering, trips me out.....but works for me....

I'd say don't sweat the ph thing too much. Try different levels and find what they respond to....

How do you check your ph? What is your ingoing water ph, soil ph and runoff ph?

water ph I us ph up and bring to 6.7 for feed and water. The soil meter never goes over 7 nor under 6. My ph run off is only a few points low. I'm going crazy,I keep walking in to N problems or nice CAL/MAG problems. I go a herm because of stress and I just can't seem to find this " sweet spot".

I believe Cangroit has it right. I use to grow with synthetics and I would keep things at 7.

Hey there - where do you get your water? If you're using regular tap-water then your problem may be a high ppm level in your water. My tap-water ppm is around 350 and is pretty much unusable. The pH is 7.5 but is easy enough to lower with pH-down. If I were you, i'd buy some RO water in the store and pH-down that to about 6.0 and see if your plants like it...if so, you may have a ppm issue, not a pH issue - and that would tell you that your water source is the problem.

Hope that helps! That was what happened to me...

Ok...so what's the ppm of your runoff, Dayzt1...?

[spunk]

1400's ppm on week 10. My water is distiled and from the store. I add cal/mag before anything in my water untill my ppm hits around 150.

This was a first grow and what a cluster *%#@! I don't recall one week in flower without having problems. When I'm in veg, Everything seem easy breezy but come flower I'm watching them die it seems.

If I read Ed's books, His study says ph aroumd 5.8-6.2 BUT when I read Jorge's book, His study say's ph around 6.0-7.0 more talk on 6.5-6.7.

The more I read,The more things seems to not work out. I talk to people,Alot of people tell me to lower my ph to 5.8 when in pro mix but have no reason as to why...

I know every plant is different but not a 5-8 point difference. I need someone to break down a good ph for soil and why is works well for the plants in that range.

Thanks for the help so far :thumbsup:

Try not to read too much, I've read Ed's book a dozen times but it takes real world experience with these things. I'm kicking myself for not using more sphagnum moss in my soil because it's good for balancing our your PH and keeping nutrients from locking up.

1400ppm at week 10 is not bad at all.... It might not be a ph issue. Your water source has been ruled out. And you say veg is no prob....how often do you flush? How often do you feed? And how often do they get plain water, no nutes?

To get the best responses, I think you may want to fill out the troubleshooting form so we can see your way and let you know where you are going wrong....

I think it would benefit you more if you were to search "ph nutrient chart". You will find many sites, some charts and they all have the same basic concept, your ph needs to be in a certain range for proper nutrient intake......

Troubleshooting form is in the plant problems section, in case you didn't know....

( Glad to see you back Rusty Trich:thumbsup: )

I flushes 3 times in one month because I was having so many problems. I normaly flush every 4 weeks. I feed them nutz,wait 2-3 days then just water waiting another 2-3 days and then nutz again. Said to say but no chart for this grow. I'm on my 10th week so I'm flushing. If I would have posted sooner in the grow,I would be glad to fill the chart out again.

It just seems as soon as flower happends N hits and then cal/mag. I hit them good with a 6-0-0 and not much happends. I also give a double hit of cal/mag and still nothing changes. I hope to figure this out and find the "sweet spot" one of these days.
