Yellowing tips of leaf

Anyone know what this can be caused by?
I have 2 ideas.
- Light stress
My autoflower have been given 24 hours light a day since seed, so my temps dont get too cold. But yesterday I re-did a lot in the growing space, so the lights was off for some hours. After that, i put it outside to get some sunlight, and an hour later back into the growbox. Could this stress be the cause?
- Nutrient burn
2-3 days ago i feeded my G14 autoflower with: PH 6.7
1ml/l bio grow
0,5ml/l bio grow
0,5ml/l top max
0,5ml/l alg e mic
Im just not sure if it is nutrient burn, since the tip of the leafs dont curve (yet)

You're probably pushing her a little bit. Be sure those tips don't get much worse, and if they don't, I tend to ride my nutrients right there. I wouldn't worry too much about her...just keep an eye on her, but for the moment, I wouldn't change anything. If the tips get worse, ratchet your nutrients back some. Good luck.

Okay, thank you! I did give her clean water ph'ed at 6.4 today. Hope this will clean out excess nutes, if this was the cause.

Definitely nute burn, give her a light flush of plain water for a day or 2 just to flush out the excess nutes/salt build up in the soil
Then when you refeed her just give her a light dose

Little update. I watered about 2L plain water in my 15L pot, and it did look the problem got solved.
About 3 days later, i watered again, but with nutrients this time.
I gave her about 1/4 strength of biobizz grow, bloom, top max and alg'a'mic.
Problem back.... All new growth is getting burnt tips too.
Can it really be that she can't even tolerate 1/4 of the nutrients biobizz recommend?
She is 34 days old.

Looks like nitrogen abundance to me. I would stop feeding untill the colour of the leaves started to getting normal or brighter shade...

Everything you're providing to the plant has something in it, nutrient wise...so yeah, maybe you're over doing it.

Im just using quite low doses, so i didnt think she would react like this. + The g14 should be pretty tolerable against overfeeding and such.

There's already stuff in the soil the plant needs, you don't need to add nutes until the 1s in the soil are used up, the plant will show you when

Well your plant is telling you something and it seems to happen after you feed, so...

Yep. I was just hoping that someone could tell it was because of too much this or that, so i could still feed the other Biobizz products. But i guess it’s the total ppm nutes in the water, right?
