Thanks

If growing Hydro some additional questions:
I expect this is the problem. pH in coco should be in the range 5.8 to 6.2. I have seen similar problems with pH out of range high among other growers, and in the case of the pic, my own growing. I shocked the plant with a dose of silica without pH adjusting it. Silica is very alkaline. The plant recovered fine once pH was corrected.

Ok, I wasn’t aware I had to do that with the Coco Loco potting mix.
The mix stays moist much, much longer than straight Coco coir.
I’m using RO water, how do I ph my water for feeding? Technically I don’t need to put any notes in the water so the super soil company claims.
Im not sure though. I did straight Coco on last grow.
Thanks for your wisdom

I forgot to mention, I guess what I have going on is more of an organic grow.
Midwest can I just switch to distilled water and ph it down and feed? Technically wouldn’t that be changing the substrate ph level?
People keep saying with organic grow you don’t ph your water?!

I have been growing organically for the past ten years. I haven’t checked our ph or ppm in the past eight years. I honestly don’t run into to many problems.

Thanks for the response! Could you give me your opinion on why the leaves look like they do? Are the roots maybe hitting the nute mixture at bottom third of bucket and reacting?

I use the coco loco a lot and treat it like soil. I’ll run a slurry test straight from the bag and typically it has a PPM range of 2500-2700 and will feed the plants for approximately 6-7 weeks with water only. Once the PPMS dip down around 800 I start feeding synthetic fertilizer at 800-1000 PPMs with a PH of 6.3-6.8. @HippieRunner1 is a great source for the organic route

Those leaf symptoms resemble a phosphorus or calcium deficiency and could be both, it’s not uncommon for these 2 to be deficient at the same time. How old is the plant and how long in this soil with water feeding only. RO water is free of minerals like calcium

I’ve reread the thread and I had assumed you were in straight coco. Coco Loco is a little different than straight coco. Some growers run Coco Loco at 6.0 as the sweet spot and treat it as a coco/soil mix. I still believe it is a pH problem given the pics.

I concur, it does look pH related. Only problem is what can I try to do to rectify the problem?
I can’t adjust RO water right?
Hey what’s up OG.
You helped me with my last straight Coco grow.
Since I cannot adjust the pH I tried some calmag but leaves look worse.
Should I supplement something else in the RO I feed?
Thank you so much, I’m worried now about this one plant. Looks like it’s on its way to death.
Ions must be present in a liquid for it to even have a pH. As RO is pure H2O and contains no ions, it has no pH. It will take on the pH of the media into which it is introduced. If you want to run higher pHed water through to correct pH, then add a teaspoon of cal/mag to a gallon of RO and then pH it from there. Adding cal/mag will add ions to the water.

Awesome!!
Thank you bro! I’m doing it now!
Hopefully it helps.

Hey Midwest, I previously did a slurry test at 6.8. So for soil that’s good right?
Maybe it isn’t pH after all…

Hey bro, what should I use for organic phosphorus? Any suggestions?

Are you growing organic? Now I am really puzzled. Let’s get an organic grower to help.
@Covertgrower you have been active lately. Who are the good organic growers?

I think I found my answer! Living soil concentrate I have it in there already but it will set my pH!
Compost Tea:
Add 2 heaping tablespoons of concentrate and 2 tablespoons of unsulfured blackstrap molasses per gallon of water.
Let stand for 2 to 8 hours, stirring occasionally. Adjust pH to 6.5 if needed.
Start with a half dose for the first application.
