PH problem may have lead to more issues. Could use some backup.

This started when I had a slight yellowing of lower leaves and buds. The ph of the soil was at 7 and someone suggested to bring it down a bit. So I got some ph down and tested my nute solution to 6.5. It turned out my ph meter was broken. The amount of ph down used was far too much. I put like 15 drops in and a few days ago I ran through another test with a different tester and I got the same solution down with 4 drops. Now I've given them just water but I think that they weren't feeding much so once i got the ph in line i believe I now have nute burn. Their color is a deep green and it looks worse under the hps. What do you think?

Keep the PH at 6.5 from now on and you'll be fine. The damage that is done cannot be reversed but don't worry. It doesn't look bad at all.

Just pHing your watering solutions will not change the pH of the medium at all. No matter what you pH the solution too it will buffer to the mediums pH withing an hour. pHing solutions is for hydro and a waste of time in soil. You say you have some nute burn so i would deal with that first. Then after they recover take care of any remaining issues. So just plain water for a week or so......

i see the N abundance, but that burn looks more like K def./lock-out. or maybe cal/mag. i'll smoke a bowl and think about it

I have to disagree....whilst only a mere noob myself I've noticed issues by NOT ph'in my water. Look at my posts and you'll see....hahaha. My fucked up cheesewreck, yellow as shit since my ph meter was broken and I was giving them something like 5.00 water......now that the ph meter is replaced and checked bi-weekly.....my new batch of babies hasn't an issue.

So while the medium might force the water to adjust.....didn't seem to do so in my case. I dunno, but I ph my water each and every time I feed/water....even if just water. Pretty sure I've read about 1000x to do that.

What am I missing A. Supertramp?

so if you ph your water how you suppose 2 bring the ph in medium down?
Add sulphur. But in most container grows there is not enough time for sulphur(lower pH) or lime(raise pH) for any real changes to become effective. It takes some time, a month or two depending on the particular amendment, for things to react and changes seen.

Your missing basic horticultural knowledge. Pretty much the only place you will read to ph solutions in a soil grow is cannabis forums. I may be a new member here but have nearly half a decade farming and container growing experience........

heres a interesting read.....

Hehe, w/o a doubt I sure as shit am missing that knowledge. And while I don't have time to read that article now, I sure will later.


Can you help explain my apparent "fix" to my issue by being on top of my PH ?? I've never grown anything.....except children and I didn't PH them either....hmmmmm, PH UP going in the frosted flakes tomorrow! ;)

Your getting better at growing? A unique experience to your garden? Can you explain how you measure the pH of your medium? POS maybe?

just ph your water don't worry about the soil. and start them on cal-mag plus once you flower use 1 teaspoon per gallon of water. your water ph for soil should be 6.8 if your using soil-less mediums ph your water to 6. expect some yellowing at the end of the flower period its natural

Horrible advice. The soil and its structure rules pH, not the pH of the solution you feed them......and additional calcium and/or magnesium when not needed with only exacerbate particular situations.....
