Brown thumb grow

[Brwnthmb]

No I’m not using nutrients (other than what is in the soil already).
I just watered it (a lot, trying to flush out N as I explained), and the plant has just entered flowering stage. Do you recommend dropping the ph to 6.3 now? What are the benefits to dropping the ph now verses just letting the plant flower and finish its life with a ph of 7.0?

Huh? I see a healthy looking plant. Looks better than mine! Seriously! I have pH tips. Where is your clawing? If those leaves mean you have Ntox, I have Ntox and have had Ntox in pretty much every plant I have grown since getting my groove together.
Are you giving more than recommended nutrients? Are you giving veg nutrients to still-hot soil?
Plants move and do things when they grow. I mentioned a time-lapse making a plant look like it was waving like a bird. That is not a joke. When you see plants turning colors other than green and taking other than fan leaf shapes, worry.
Now, check manufacturers recommendations. I know you're working with equipment issues. When it comes to flushing, that might not be the best toilet.

Yes. Too much N.

Solution is to flush with water. pH it if you can around 6.3 and let it flush right through. You want a gallon of runoff or more.

You can't settle N out of the plant by flushing but van get it out ofyhe soil.

Are you feeding it nutes?

I can’t “refind” the information on dark green leaves, nitrogen, and flushing the soil, but I do remember that the solution to the problem is to flush the soil with water. I also remember plus 20%, but I don’t remember if this is the recommendation for watering normally or if the +20% is for flushing excess nitrogen. (Does anyone remember where in the drop down menu that this info is located?) thank you.

ps. I ran 6 liters of water through this one which is 20-100% more past the “pouring out” point, depending on where that is, 3 or 5 liters.
My hope is that I didn’t overwater it too bad. The leaves are curled up like a claw now. It’s a mystery to me as to how the soil knows when to let the water flush the soil and when to hold the water and cause problems.
Thoughts?

Thank you Rwise and Bluey

The Apera Amazon store seems to be the go. US$94 for the kit

[Rwise]

You dont need to spend as much as I did on test equipment (My PH meter ran near $400 with supplies), but those cheap meters are just that cheap.

[Bluey]

You measure the pH inputs. Easy as. Don't bother with measuring runoff pH.

Don't ask me how to use a pH meter that is +/- 0.25. I'd bin it.

Apera have an Amazon store. Get storage fluid and calibration fluid in the same order.

If you are giving nutes also consider the PC60 instead of the PH60.

Don't bother with the Bluetooth model.

soil PH in veg is 6.2-6.5 in flower 6.5-6.8, again a PH of "around" 7 is "around" to high. Some plants can deal with it others cant, one pot may have got more of the buffers than another pot. Treat each one as an individual, and deal with its needs.

I have not yet upgraded my ph meter to an apera ph60 (or equivalent) as suggested by Bluey and Rwise et al, so I’m stuck with my old meter. Nevertheless, The ph reading for this plant and with this meter is 7.0.
I measured my other plants for comparison. Out of 9 plants, 7 had a ph of 7.0, one was 6.7, the other 6.8. (The 6.7 is one that is in flowering phase.)
So, the meter does seem to be repeatable. As far as accuracy I can’t say. ( I do plan to replace it with a better one. I just haven’t done it yet. Your advice didn’t fall on deaf ears.)

Get your pH right and the plant will look after itself mostly. Get it around right and, well, your plant will be around right but never be right.

I get your meaning (to ignore the meter) but do you think that the meter is faulty, or are you saying that the time to water is before the soil dries out at mid level and below?

[Brwnthmb]

Screw your probe.
You know what dry dirt feels like.

I did ignore the probe and watered the plant.
thanks

Just for reference, this is the plant I was just now asking about watering and the moisture meter. I did ignore the meter and watered it thoroughly.
My question is about the yellow spots you see on the leaves, mostly along the center line. The chart and drop down menu lists watering, ph, or nutrients as a possible cause. However, ph is around 7, and nutrients should be good. The soil is a relatively fresh potting soil and my other plants do not have this problem. The older leaves do have the problem more than the newer leaves. Do you think that this may be a holdover problem from the plant being overwatered in its early life? (I don’t know that it I was, but it stands a good chance. The seed germinated 7/22. The plant was transplanted to 3 gallon on 9/26.)

But smash it first
