PH'D WATER AT 6.5 BUT RUNOFF COMES OUT AT 7.0?

Massgrower98 said:

I just feed my plants a compost tea and checked the run off and the ph was at 7.0 when I just ph'd the water to 6.5 ... this one girl scout cookie I have in particular is showing more signs of deficiencies than any other plant... what should I add to my soil or water to fix ph?

Run off means shit, ignore it.

Do a soil slurry test if you're concerned, add dolomitic lime as a top dressing if it really concerns you.

The issues look like mine did, it was a CalMg issue.

Add more pics, list your water type and nutrient type.

What kind of soil...etc..etc..

So what? Why are you checking the pH of the runoff? Your issues are more likely due to a hot soil with unbalanced nutrient levels. Too much of one thing will lock out other things. It's called nutrient antagonism and is responsible for a good percentage of issues growers experience.

So you think I should just cut back on the food and just start using water ?

Oh, and after you amended the soil did you let it cook for at least a couple of weeks? A month is preferable and longer is still better yet.

There should be a sticky that says runoff PH is pretty much inconsequential.

Use your TDS meter and measure your runoff compared to tds of new nutrients. If runoff is measuring higher, you have lockout and need to flush. If runoff lower, your plant is uptaking neuts and needs a supplement with CaMag. Different strains require different mixes. Your GSC looks like she needs more calcium to me ,so if runoff high I would add more cal mag to the new mix after flushing. and rebalancing the ph to 5.8 .

Ok yeah I havent checked my ppms recently I'm gonna do that tomorrow when I flush... all of my plants are starting to get nute burn at the tips of the leaves, and yellowing spreading from the bottom up... let me put this out to I havent feed my plants straight water in over a month I've always been putting something in my mix. whether it be silica powder, aloe vera, or some type of tea so should I just flush my plants with water and ph at normal 6.5? But i will check run off either way and if I need to add calcium I've got this source of calcium from roots organic is this a good product to use?

You can't check the ppms available to the plants by checking runoff when you "flush" your plants. Whatever number you get is meaningless.

You say you heavily amended your soil, then you added 2 different fertilizers, then you watered with teas, silica powder, etc... You also say you've been feeding them something every watering. Why would you need to add anything else? If you had a heavily amended soil like you say a top dressing of the Gaia Green is all you would have needed if even that. You should have been feeding plain water. You definitely don't need to be adding more stuff with that overpriced Elemental Roots stuff. You just said all your plants are starting to get nute burn. Now you're talking about adding more nitrogen? Why would you think feeding them more would be the right thing to do? That makes no sense.

You seem to be in the "add more" mode to fix your plants when the problem is you've already added too much.

You haven't shown a picture of the entire plant just some nasty looking leaves you cut off and many should have been left on the plant.

Heres a pic of gsc on deck, second one where I'm showing the bottom canopy is the bottom of my sour diesel also yellowing up from the bottom ...and because I dont know who to believe on this rollitup page, this other guy just said I should ph my water to 5.8 and add calcium if my tds runoff is higher than the nutrient tds in water ... your right i shouldnt of been adding in random amounts of amendments back when I broke down my soil , and I need to be just adding water more often ... sorry I've only been growing for a year and a half so really just trying to learn thanks for your time...
