Need help with nutrient lockout

[faceto27]

I understand what your saying, but my problem isn't from the ph going lower, the problem as I can see, is that between the waterings the ph went up, thus causing the lockout. I've flushed the affected plants and glad to report that it dosn't appear any serious damage has been caused. In a couple of days, when its time to water again, I will check the runoff for the ph level.

From what I can gather googling promix, the consensus appears to be to lower the water ph level down to the high 5's. I guess an acidic medium like this, the ph level rises between waterings to achieve that optium level in the mid 6.0's.

Oh Stinky.......can you help clarify this please?

Promix is not a hydroponic medium, and I wouldn't be aiming for the more acidic numbers that were being thrown out here.
Treat it as if it were a soil mix.
Nothing to fear with a flush, it's just another step in growing. Salts and nutrients build-up, which will lower your ph over time. Be careful of keeping the soil too wet for too long. (don't water just before a flush, nor just after. Can cause root rot.)
I add my nutes into the final 1/2 gallon of flush water, then let it be for a few days till next watering.
HTH...

Rusty,

according ot the link you provided, they state that Promix 'is' a soiless medium. Should you not aim for a ph level of high 5's with soiless mix?

OK...I do not know all this to be fact, but by looking-up definitions it appears that:

Soil is what you dig out of the rose garden at the park. (clay or sandy base, ammendments, compost, rocks, bugs, forrest leaf-litter, weed seeds, cat shit) Some folks around the cannabis community used to call this dirt, and should be avoided if possible.

Soilless products are individual components mixed together to create a growing medium. It's a method of controlling the growing medium, to meet a gardeners needs. Gardeners have different needs, so different soilless mixes are available. Cactus mixes, African Violet mixes, seedling mixes...
That's my story, and I'm sticking to it. (until I'm schooled otherwise, lol)

This may be a bad explination, but I think I get the idea, lol.

Anyway, do you put brownish stuff in a pot, add plant, then grow/water the plant, or do you put a plant in a pot, and splash water directly on it's roots from a reservoir?

Perhaps someone else has a better explination as I'm really not 100% positive?

Compromise and aim for ph of 6. I consider a medium hydroponic if it is INERT....and peat moss isn't. We DO need the Stinkster here.....

Rusty,

I put the stuff in the pot, add plant, then grow/water the plant. I use a regular garden watering bucket to water them. Not sure what you mean splash water on it.

[Rusty Trichome]

Was trying to find out if you grow hydroponically, or in soil...without using the word soil.

Lots of planting mixes or potting mixes are soilless, however you still need to use this stuff like it's soil. Would the name "designer soil" help, instead of soilless?
Soilless mediums used for hydroponics are a different animal and you should not concern yourself with keeping your 'potted' plants to hydroponic standards. It can/will kill your plants doing so.

I agree with Weedhound...we need Stinky to chime in and give us a really cool, really simple link. The more I try to explain, the less I think I know, lol.

Face, this thread is kind of confusing, and my pain meds ain't helping the thought process, so this may be a stupid question, but, do you understand that you absolutely MUST adjust the pH of every drop of liquid that you put in your pots? It seems like you are saying that you are watering and flushing with unadjusted water.

Pharma,

Yes, I was just watering without any regard for the ph of the nutrient or water going in. I was mislead. There are a couple of sites, that people have saying with Promix, because it is ph adjusted, you don't need to monitor your water or nutrient ph intake, because the Promix will adjust. I should have known better, it just didn't make any logical sense.

One of the plants, I think I may have to call a priest. :sadcrying

I flushed the affected plants yesterday, all of them seem fine with the flush, top leaves seem happy, but one plant the leaves really have basically collapsed. Furthermore, I noticed that soil, was very very damp still, even though its directly underneath 1000 hps, and a fan blowing for all of them. Much more damp than the other ones. So, I have just given it another flush, this time I measured the ph runoff.......it came in at 7.9. So, I'm thinking that I have a very heavy salt build up at the bottom of the pot, thus the high ph, and the very poor drainage. I think this plant is a lost cause, unless someone thinks there is something I can do to give it some hope, aside from an exorcism. The plant is 6 weeks old.

You'd be amazed how much abuse these plants can take. Drill some holes in your pot, sides and bottom, to improve the drainage then flush with pH adjusted water until your runoff comes out where you want it. Water with 1/4 strength nutes.

Priests can't help plants - it all has to do with the birth control issue. You need to get naked and dance around your grow room while waving ostrich feathers. It's the only metaphysical treatment that really works.
