Small yellow tips on 28 day old autos

[Scar17]

hey back again,

28 days old, determined that the roots have bottomed out in the fabric pots but corrected the issue.

Tips on 3 of the 6 plants are yellow.

Overall health looking good so not too concerned. I didn't know if the tips changed color because the roots bottomed out or it had some other deficiency going on.

Thanks for looking.

Overall health seems to be okay.

Looks like good old fashion tip burn to me, Scar. And judging from the color of your leaves, nobody is starving for N.
Keep an eye on it for sure, but quite a few growers who push their gals will run up to the point of tip burn and then back off a smidge (or not).
I get the same thing, usually with nutes that have higher values of nitrate and ammoniacal nitrogen.
One reason I always water to runoff is to help move the salts from my soil. Excess salt can also burn tips, and worse.

Scar', this is a case of mild nute burn; did this start recently? If so, reduce the conc. of feeds some... what are you using, and how much? Did you get that Accurate 8 soil pH probe yet? it's things like over fert'ing that can often start off pH issues,.. are you adjusting your feed pH and water too? It's worlds easier to monitor proactively than fix after the fact! That pH probe is as key as your pH meter for liquids,...

Hey bud, it started 3 days after their first feeding with nutes. I am only using 50% nutrients so far. I will take a pic of the nutrients I'm using. I'm lazy right now and don't feel like listing them all. But for sure im gonna cut down the strength of nutrients. I do prefer to slightly underwater and water more often so I was thinking about just keeping same nutrient strength but add more water. They average 1.25 liters of water every other day per plant. I do not have a soil meter but will get one asap.
I do adjust my ph absolutely last when I feed. I ph to 5.8. I use my baseline feed last then ph. Also can you take a look at the pic I added. Tell me what you think, the leaf tips are bent over. Thanks Waira

nute burn, nothing more, nothing to stress, happens most every time I add a single drop of nutes in mine.

they will grow wonderfully dont streess

my girls are all in last 2-3 weeks, 0 in nitrogen intake of my nutes, average 0-9-4 and they still get a tip burn. seems anything over plain water gets mine to khaki out a tad, but hasnt done anything negative.
I think these autoflower...ie mutant plants already..... just get stressed at slightest fart of anything over plain...lol, but thats just my opinion

As @Waira said, too much N.
And as fast as that clawing started, way way too much, at least that's what it looks like.
Give us a full breakdown if you would:
Grow medium, exactly what and how much you're feeding and how often, etc. A good rule of thumb for autos is to start at 1/4 strength and work up from there.
Right now you're overdriving them. Might want to let off the gas just a bit.

Okay I will do my best to break down what I'm using.
I started with roots organics 707 soil, I used 3 gallon fabric pots and bomb seeds (THC bomb). I completely drenched the soil prior to dropping the seeds in and let sit for a week. Once the seeds popped from the soil I watered once a week for the 1st three weeks(5.8 ph). 1 to 2 liters per feeding.

On day 21 I started veg nutrients, in the order it's written down is the order I add to the water

1. 8 liters of water
2. Light layer of Great White Mycorrhizae
3. General Hydroponics (GH) CaliMagic 1-0-0 / 4 ml in 8 liters
4. Microbe life Photo plus 0-.5-.9 / 12 ml in 8 liters
5. Buddas Tree Solar Green Power Silicia / 2 ml in 8 liters
6. GH Rapid Start 1-.5-1 / 2ml in 8 liters
7. GH Maxi Grow baseline 10-5-14 / 4 tea spoon in 8 liters
This usually gives me a ph of 4.5 and I up the ph to 5.8 once I add the baseline.

I feed three larger plants little extra out of the 8 liters. The three larger plants are the ones with the nute burn on the tip. One of the smaller ones has the bent tips. I split 8 liters between 6 plants

I've been watering every other day since day 21, today is day 29. Today was a feeding day but I skipped it and posted here first.

All the dosage is 50% or less than 50% recommended regular feeding.
Also guys when should I switch to flowering nutrients.
