Potassium deficiency? Or light burn

Had my Mars hydro light about 21 inches above canopy and like 65-70% bright. So not sure if it’s just light burn...

also wondering if it could be a Potassium deficiency due to the yellowing of the tips of the leaves, but I’m not sure how that could happen when I’m using SoHum living soil.....and I just transplanted into 7 gallon fabric pots with the SoHum 2 weeks ago.

Could be minor burn too. Since you just transplanted into new soil, that would make sense. Especially if it's a living soil.

If you haven't lowered or turned up the light it shouldn't be too much light.

I'd just give plain water for a bit and see if they improve. If they don't look better in a week, maybe give it a dose of Neptune's Harvest Fish and Seaweed and see how they react.

Thank you so much for responding!
I did raise my light earlier to 24 inches and lowered it to 55%, and I’ll see if that helps too. I haven’t given any nutrients, only water and real growers recharge, but if the problem continues to get worse then I’ll definitely grab some of that Neptune’s harvest fish and seaweed.

I greatly appreciate you taking the time to respond bud.
And I was also wondering if it could just be burned tips, considering it is a new soil and they’ve only been in for 2 weeks. This is my first go with organics and living soil, but I thought I remembered reading something about the organic microbes and organisms taking a little while to break down and feed the plant, which would make sense. The plant seems healthy and perky other than the yellowing up at the top, seems to be growing pretty quickly based off of my daily photo shoots .
Thanks again bud

It doesn't have to be Neptune's Harvest. That's just what I use occasionally. Usually I just give plain water though.

Ya, I was thinking slight burn since the soil is fresh.

These LEDs are potent so plants need a little more food though just to keep in mind.

I top dressed a week ago and it was a little potent. My leaves looked similar, but the plant is starting to adjust now. This is no-till living soil.

That’s a relief! I’m hoping it adjusts to the soil, but it seems to be growing so maybe I’m worrying for nothing.
How old is your plant now? Pretty big!

I was hoping to flip to flower this weekend if it seems to be doing ok

It's not that old. It's in a 15 gal pot though. This is my veg tent. I have plants at 5 weeks in my closet. They're all clone only Green Crack.

I'd give it a week. I bet they look better then.

I agree with @PadawanWarrior. Just some mild nute burn and as long as it doesn't spread along the margins of the leaves it won't be a problem. Don't feed any extra nutes for a while as they won't need it and you'll just increase the burn effect.

They already look like they are growing rapidly as they adjust so make some room for them. :)

:peace:

Just seen this reply from you....thank you for taking the time to respond, I am definitely leaning towards a mild nutrient burn as well, it seems to keep happening to all of the new growth that appears, but never gets passed the tips really. The growth is crazy! It doesn’t look like it until I look at pictures from days ago and it’s really bushing out nicely right now!

can’t thank you guys enough for taking the time to respond. Means a lot

The pictures I attached are only 7 days difference....I’m thinking that I’m going to flip to flower Friday (gave them a light defoliation yesterday to open up the middle more), since I’m only working with so much room in my 6 foot tent
