Is this nutrient burn or light burn

Hello everyone, First post here.
I've done a couple of grows not very experienced still trying to learn,
I transplanted and topped my plants two days ago into 3 gallon pots with FF happy frog soil, with 20 % worm castings and 2 tbsp of Gaia greens dry amendment organic fertilizer per 1 gallon of medium. ( 75% all purpose 4-4-4 and 25 % Power bloom 2-8-4)
I noticed with morning the tips top leaves are starting to turn yellow, I'm wondering if this is the start of nutrient burn or light stress? Or is it from the stress of topping and transplanting in the same day?
For light i am using a Spiderfarmer LED SF-2000 it was at 60% and 24 " away from the plants. I turned it back down to 50 % this morning.
Any advice would be greatly appreciated.
Happy Holidays!

Hello, i believe my plants are now showing signs of a deficiency,
i did start LST the plants and watering when needed since last time i posted.
When i checked on them this evening some of the younger leaves are starting to yellow on the tips, not really sure what this could be.
Is it from too much nitrogen? Should I be worried?
Any help would be greatly appreciated!
Thanks!

I'd dial the lights down and see if they are happier or sadder. Maybe you're also letting them get too dry? I've seen plants do weird things when you let the soil get too dry.
I did have the light set to 80% turned them back down to 60 % when i noticed the yellowing. I'm watering about every 5 days, leaves aren't drooping and the top 2ish inches of soil is dry below is still slightly moist when i water.

I'll probably add some liquid seaweed next water if lowering the light power doesn't improve anything.

No that's blanched tips from excess nitrogen. Note the fading edges of the leaves in the latest picture. That's potassium deficiency.
Could the excess nitrogen have caused the potassium deficiency , like a lock out?
What would be the best way to correct this?

Pretty sure happy frog has feed in it. You should have transplanted then waited until they bounced back and then add Gaia after. You likely added too much in the medium before the plant was ready for it and your ph is off now causing a lockout of other nutes. To me that looks like cal mag def maybe potassium. But adding more shit into your medium is just going to compound your problem.
Why use foxfarms soil? So many people have issues with the stuff it's a real noodle scratcher why new guys flock to it.

Also there's really no reason to buy the 4-4-4
I just use powerbloom 2-8-4 and add insect frass sub 1tblsp frass for 1 tblsp bloom. That'll get you the extra n you need in veg and provide Chitosan as an added benefit.

I've just been trying different soils each grow. this is only my third one.
I thought happy frog wasn't as hot as others, but it is what it is at this point.

so basically i should just try and correct the ph of the soil ?

PH was too low run off measured at like 5.3, and PPM was way to high like around 2000.
definitely locked out nutrients,
I 100 % messed up by adding so much extra shit to the soil during transplant.
Flushed plants, hoping for a good recovery.

Don't worry about runoff ppm in soil

Don't bother chopping and changing soil mixes. You will never get consistency.
