Can you identify this deficiency?

[Macintyre22]

The plant (Cherry Pie) is 5 weeks old, being grown indoors. Using Advanced Nutrients (micro,veg,bloom) as instructed with a PH of 6.5

Can you please post a full plant picture? That's Potassium deficiency by the looks of it, but a whole plant pic will provide a more complete picture.

Also, what medium are your plants in?

They are in soil

They are in soil

Which soil? A lot of new growers say "soil", but really it's coco or peat or a blend of both. It matters very much.

What water you using? Ppm/ec of water before nutes added?

Like I thought...

• Lightweight, sphagnum based peat growing mix with added Mycorrhizae for added root support

You're in K lockout due to too high a pH.

Drop your pH to 5.7-6.2 in peat. For the first couple watering, ensure it's at 6.0 or a point under (ie. 5.9). This will ensure that K will be uptaken.

I'm using Brita water, I add the nutrients and then adjust the PH with a ph meter and ph up/down if needed, but the nutes I'm using on this grow are from Advanced Nutrients with "perfect ph". My last 3 grows have been done this way, only difference is I spent a little more on Nutrients. I used to use RootFarm nutes

Thanks a lot man, I will give that a try! The ph after nutes is usually between 6.3-6.6, I will lower it and hopefully that does the trick. I really appreciate the help/feedback

You will need to add cal mag to filtered water. Is your tap water bad? What is ec ppm of tap water?

 

[Macintyre22]

Im not sure, I will get a ppm meter to find out. What's getting me is that my other tent is using the exact same medium and nutes and they are looking healthy

Then modify the pH of only that one plant for now, and see how it, along with the other current healthy ones behave.
