Is this likely low pH?

Cut back on feeding and lights. the ruff edges is overfeeding. It usually shows like that on autos instead of nute burn tips. The twisted leaves and light tops and droop in leaves is from light. Plant leaves should be in praying or resting at side position. They are running from light.
Thank you for your comments guys!
First of all Grow Monster, that's an interesting possibility! Another expert friend of mine thinks it's low ph from the photos so good to get a few opinions.
I transplanted into those pots almost 1 week ago from 7g up to 12g airpots.
It's a homemade organic soil mix, very close to the COOTS soil mix or buildasoil.com.
I gave a big couple of waters last 2 times (3 days apart), possibly too much I wonder... about 1.5l of water, very slowly from an airpump sprayer.
I included a small dose of BIO Bizz Grow and Bloom.

I don’t feel it matters with airpots
The roots self trim
To be fair the roots arent at the end of the pot yet as they just went in a few days ago!

It looks like underwatered
Those pots need soaked each watering which admittedly is difficult as the water keeps weeping out the sides

Check lights first. Always try the easiest fix/trouble shoot first. Download photone app and let us know where your par is. U should be somewhere in the 500's. More then that would explain why they running from light. If that is the issue or part of it u will see results soon after adjusting.
That's a neat app! My light is a mars hydro FC 6500 at 50 percent. It's giving me 300 or so par reading using that app. Guessing it's only seeing part of the spectrum though. Still think it could be too much?

U sure thats the par? Be sure u got it on full spectrum led. From that reading u are on the low end but it seems strange. 650 watts at 50% is 325 watts. Whats the light distance? 300+ watts would need to be minimum 2ft+ away.

More like 1 foot away, even less... could that be it? I find phones cant correctly pickup the light readings personally so wouldn't be surprised if it was considerably higher than the reading.

It sure does look like a PH issue to me but I’m not an expert. I get this once in a while when my ph swings a bit too far but all things mentioned could be a possibility. Start with easiest first as mentioned and give it some time to see if anything changes then move on to the next easiest change and keep repeating till you get it pinned down.
I have one in a 1g pot right now doing same thing cuz I didn’t water it often enough and the water that was in the coco the ph has risen up too far.
mall the folks posted above are far more knowledgeable than me but I have seen this from ph swings. Hope you get it figured out best of luck to ya

You might want to hit them with an epsom salt foliar spray. The interveinal yellowing and purple stems looks a lot like the magnesium deficiency I just had. Epsom salts cleared it right up (1 tsp per gallon sprayed just before lights-out).
Might be other things that can cause that but it looks very similar.

Think you might be right...
Soil PH Is fine, about 6.5-6.75
Lowered light and didn't help, plants looked generally unhappy until I raised it again now they're perky again.
Watering I've kept the same, 1.5 lt, a light feed of bio bloom and grow since the soil mix I made is coots recipe, so quite hot.
Gave a foliar feed of bio bizz bloom and Grow, also added some calcium carbonate to the soil, sprinkled on the top and mixed in a little. They do all look a bit healthier but reckon if I can get some epsom salts for a foliar feed, this is the way!
