Red Stems & Pale New Growth

Perhaps you had a minor deficiency and over compensated, it happens.

PH in soil usually isn't that important, but when it is, you're going to want to do a slurry test to get the pH of the media itself. My suggestion of 6.4 is because I think you should flush, for normal feedings it's going to be down to what's going on with the pH in the media... though, you keep the beneficials thriving and pH won't matter much, so feed them.

Slurry test?

Take soil from the pot, mix it with water 1:1, then check the pH; this will tell you what's actually going on in your root zone. If you can check the pH/ppm of your feed compared to your runoff, this will also provide information about what's going on in the pot.

One time I fed at 6 and the runoff was like 4.5.

Well water can be an issue but not always. You said your well water is Ph adjusted by you before use. Did you know that Ph and well water with high alkalinity or carbonate hardness are not one in the same. Meaning you can use correct Ph water all day long, but if your water is too hard with high alkalinity you can be driving up the overall Ph in your rhizosphere no matter what Ph you have your feed water set at. Its a good read. Dig in......

I will try to find my post from a few years back as this could be part of your problem........

I tested my runoff... It's was 5.57 and the original water pH was 6.70...

5.75 not 5.57 my bad

you aren't getting it. read the article I posted for you and it will become clear...... if you have questions ask after reviewing ask away.......... I hope you get it sorted out... :D

In the article isn't it saying that high pH along with high alkalinity is where the issue come in to play??

 

[bibbles]

High alkalinity will buffer your soil through build up, and cause pH to rise through the neutralization of acids; however, since your runoff is more acidic than your feed, we can fairly assume that acids are not being neutralized.

Drops in pH to runoff are often caused by excess salts, but there are other reasons as well; do the slurry test. Sulfur becomes less available in the lower pH range as well.

Do that foliar now, sulfur deficiency can take a while to recover from, and you won't see much growth till it's corrected. :/

Thanks Alot I definitely appreciate the info

is this a case of preflowering or an auto?? 18/6 lighting, 5 wks from seed, unknown strain but a friend got it from a dispensary, (dank most def) any ideas??

If it flips with put 11 to 12 hours dark...then its probably auto

So if it were u would u flip to flower on at least that plant... It's in my veg tent... I have flower tent going now(wk2 flow) but it's a scrog setup

Just leave it in the veg tent..itll finish and if it herms then it wont trash veg plants.
