Small yellow tips on 28 day old autos

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

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.

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,...

Okay guys let me know what you think, no more gas I guess gonna coast for a few.

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

From my experience so far totally correct. Sensitive little biatches

I saw your nutes, but am missing the rates and frequency you're feeding. Foot off the gas is good right now, 1/4 nutes.

Scar, the soil is fairly rich itself, and your pH'ing needs to be in the low to mid 6's,.. mid 6's for sure now, knowing this new info,... soils optimal range is around this pH Oooo, that's some N-tox' happening with the tip claw, definitely ease back on the Maxi' some! I'm a bit leery of the K inputs too, but see no prob's yet,.. i say that because of the high K in Maxi' and the Silica supp' is likely a Potassium Silicate formula, maybe 0-0-3+..? ...yeah, you cam switch to bloom now, a good idea, this will reduce the N inputs as well,.. go less than half strength on the primary nutes,... what are you using, and it's NPK for bloom?

Thanks Waira and Renaissance Redneck. I will raise my ph some, ease up on the nutes.
I will take next week to run less maxigrow in the next 2 feedings that takes me to day 35 to begin bloom nutes
Unless you thinks it's wise to switch to bloom immediately
My bloom nutes are

Maxi bloom
Cal mag
PS Sea Green humic acid
Buddas tree pk 9-18
BT flower burst
BT advanced meta boost

Good call, in my opinion, backing off a bit.
This is where the science comes in, Brother. Understanding not just what you're feeding, but understanding why you're feeding it.
Just for reference, Waira saved more than a couple of my early grows. Mad skills, and worth listening to. Except for that flat earth crap.

Earth is flat??
