I’m having yellow leaves week 1 of flower I test my ph run off at 7.5 when I water I water at 6.5- 6

So across the world all those with bad ph tap water and ferts that swing high or low that grow non marijuana plants indoors in soil with zero ph adjustment.....

Htf are they managing when most of you cant?

Hmmmm :-)
 
problem a lot of times is people fail to follow the kiss method, if you just grow as simply as possible without hovering over the plants adding this and that monitoring everything like helicopter parents you'll get results, a good healthy soil or coco medium with non salt or chem based nutes will buffer itself naturally. all this shit we are sold from cannabis nutrient manufacturers is mostly rubbish that does not promote healthy mediums make it a harsh environment for microbes and bacterium to thrive they make the best nutes you can get. We need as growers to learn to feed the soil not the plants, then the soil will look after your ladies.

yeah my first grow was under the teachings of an old school organic head. when i asked how i should monitor my PH and if i should check my PPM he laughed and said he hasnt checked either of those in his 30 years of successful growing lol.

So, you try and pick apart a reference I gave, and I can give many more. Then you tell me that my reference is too old (2006), yet your growing experience of decades is accurate? I could go on to list four books I own, and a half dozen websites instantly that confirms what I have suggested, none for your advice. A bunch of anecdotal evidence, as per usual on this forum. Twist people’s words, shoot down their references, provide none of your own and then call bullshit. You say soil pH isn’t important, then go on to say how it can change and what soil pH meter you support. Pick a side of the fence guy, you confuse people spouting bibles of your own unsubstantiated anecdotal BS. As soon as you realize you got called out, you write a dictionary to sound smart.

Soil pH rises and drops as we water... you ask when we are checking it? OBVIOUSLY you check soil run off when it is wet, because it was watered. And I didn’t say I RELY on run off pH. I don’t even take run off PH so button it up old man.

I take year breaks from this forum because old hippies think they know everything and desseminate wrong info, like telling a guy with yellowing old leaves he has a high P issue.

I feel bad for the beginners that listen to this shit.

Well, well.. Reading 4 books and the internet made you an expert eh?

Look smart ass. Over use of high P and K bloom foods.....Cause that issue in early bloom

Go ahead and give it more N! Won't return those leaves to green and working.. Not with the P as high as I suspect it is. Adjusting N here, will not work to fix this problem!
The real question is, Why is the plant expressing low N? Answer: Because the nutrient maker has you start on high P bloom foods,,,,TO EARLY!

You asked for an explanation,

Can one of you guys talking about his issue being high Phosphorus explain what you mean?

Then bash it because you can't find it in a book?

More like you don't understand my point..

pH wise?
Bottom line is it's soil. Soil pH is set by the make up of the soil, and buy the plant in it

Worry about what goes in, not out........

Kinda funny how many agree with that....

Let me finish with this point...

Your pot growing book collection.....Was written by old hippies! Go search the net for that.....

As a simple rebuttal, I’ve been growing over 20 years, taught by my mother who was growing before the internet. I let my irritation of the day spill. I like old hippies. I read a lot, probably overbalanced in that direction rather than constant hands on over my hobby... I could not find any reference to that chemical interaction.

Keeping that in mind, I will be mindful of high P having that effect and see if I can observe it or experiment with that myself. Sorry for being so rude.

The way nitrogen deficiency starts is it begins from the bottom of the plant and works its way up through the stems and branches. According to Penn State University.

You may have noticed some of the lower leaves a pale green to yellow color.

This is a sign of a lack of nitrogen with your marijuana plants. Not sure where you’re getting your information but it’s wrong and adding bs to water to lower or raise the ph while growing in soil is absolutely wrong I have had more plants look like they have deficiency’s and it was simple the ph solution killing my plants.

It was the nitrogen I added some grow to the feedi
