Can someone help better understand

[Halloweed]

Hello again. I have a plant that seems deficient from lockout. I think from N toxicity and ph. I don't quite understand PPM.

I tested the runoff and had a ppm of 1200 and a ph 5.8. I flushed her with 2.5 gallons of water around 6.8 ph. After flushing, her runoff is now lik 550 with a 6.0 ph.

This is an organic grow. 5 gallon pot. It's an auto around 3 weeks into flower.

So I'm not sure if she's good where she is at, or if it's too low. I'm afraid after flushing there's not much left in soil.

Should I use fox farm tiger bloom to get the nutes in quickly? I assume going organic will take too long to become available.

My other plant had runoff of 2700 ppm. I flushed her as well and she's now at 1500 ppm and ph of 6.0.

The numbers seem all out of wack. I'm not exactly sure what to give her now.

Don't give them anything and when you do, (a week from now) just half of what's recommended. Autos don't need much to flourish. And please get the "organic" out of your mind, your not growing organic, your bottle feeding.

Thanks. I will wait a week before feeding.

I was growing organic using Dr. Earth and worm casings but from here on out I'm just gonna finish with bottle nutes I guess.

I tried making a decent organic soil. I think next time I'm gonna go with purple cow or buildasoil.

I've grown autos with just good soil and water, no bottled nutrients needed. Dr Earth and worms castings is plenty.

Hard to say without seeing the plant. Organic nutrients are slower, but that can be helpful. Water-in organic fertilizers don't take long.

It's important to understand the differences between synthetic and organic nutrients. I tried synthetics before I knew the difference. I've since been a much happier grower with much happier plants since I went organic.

I'll post pics of the full plant tonight. For now I'm just doing straight water. My initial hope was to create a soil I just needed to water.

Then all nutrients would need to be in the soil from the start. I think that would be difficult to do, but perhaps possible. That has never been my goal, but I've come close using organic nutrients and fostering healthy mycorrhizae. I've always added something, though. Some nutrient adjustments are unavoidable, I believe. Some nutrients seem to work well when watered into the soil. Timing can matter, too.

Your first post told me you were mixing growing methods. There are major differences between using organic versus synthetic nutrients.

Ok. Cool. I'll read up on that.

Just took pics. Alot more yellow. I think it's hungry for something But not sure what.

It looks like manganese deficiency. Here's a picture from dutch-passion.com. According to the site, "It’s unusual to see genuine cases of Manganese deficiency. Often it is related to excess Iron or high pH."

What I would think if those were my plants and Im sure that the PH is okay:
1. Crispy tips curling only on the top canopy and not through all the plant = light too close
2. Depleted leaf/leaves on the first node = hungry at some point, probably nitrogen
3. Tips pointing downwards = too much nitrogen at some point
4. Random yellowing on top leaves = light

Yes, you can have nitrogen toxicity and nitrogen deficiency, it just takes a bit too much N once and too little a couple of times.

Honestly it looks pretty similar that would be:
5. Dark spots on yellowing leaves = probable manganese deficiency aswell.

"I tested the runoff and had a ppm of 1200 and a ph 5.8"
There we go, that explains the iron messing with the manganese. Never go below 6, good that you catched it before it affected them more. At below 6ph there's also another problem which is that alumina becomes water soluble and its toxic for your plants and for you. Alumina is found in every peat based soil, such lows PH you can only get away with in coco and it might eventually cause problems too.

 

[Eledin]

This is a very generic chart for soil that I have saved in my computer, as you can see at a ph of below 6 iron is absorved in higher quantities, and so its manganese but that doesnt mean that the plant is gonna be able to process it, because there's a nute umbalance.

Flush and reset...slowly feed

So the flushes are done, now about the nutrients. Unfortunately fox farms is not available in my country but most organic liquids have some chemical to make them available sooner for your plants. In my case, Iguana Juice has phosphoric acid so the fish hydrosolate can be absorved way quicker by the plants, but yes still microorganisms play a big role. Just rebuffer your soil with the dosage you usually give them or slightly more and reintroduce microorganisms because after flushing Im not sure you will have a healthy enough population to colonize all of the pot again quickly.

 

[Eledin]

For a faster feeding you can do a basic compost tea. Just mix your nutes with 1/4 the water you would use and introduce microorganisms, let it marinate for a day, 2 would be nice but it might ferment, which is not bad but might lower ph and then you will need to add ph up or silica. Once its done mix with the other 3/4 of water and water.

Alright, thanks. Everything you've said is pretty spot on. Gonna try the compost tea. Do you think I should get epsom salts for the magnesium? I have calmag but not sure if it will lock out anything

You won't need Epsom salt if you're using calmag.
