VPD or what? Stubby bushy growth, weird leaves

[D350]

Maybe you can help me.

I have 2 sets of Northern lights in soil, around 2 weeks apart.
Soil is good quality, tried many times before.
And my friend is rowing same plants from same mother in same pots, same lights and doing great! WTF moment!

No fertilizers added, first 2 weeks sprayed every 2days with water, ph on spot around 6,5 (have two testers for make sure), temperature ideal around 25C, RH maybe little low around 40%.

Older batch is showing really short bushy growth, with short stems and leaves with not 5 as normal, but 3 or even only one finger...also twisted here or there, some looking N heavy (dark green), some like the have Mg deficency....Can VPD do this???
I think only things that could cause this are:
-VPD (Low RH) but now I spray them 2-3 times per day, have 2 humidifiers and rh 50-60% and dont see any substantial change
-something is suddenly wrong with my water, was fine before. Now gort some bubblers...
-some sort of desease, pests...? No flys, no nothing iI can see, no spider mites

Thanks for your input, all ideas are welcome

HPS photos (sorry for that, will try fx lat

er) are from older ones, MH are from young ones

Some more images without hps on.
Just a note, I have a classic setup, fans, 600w hps etc. Pulled 1g/watt on last grow, 120g per plant...
Not sure, what is going on. I see all possible problems, Mg def, P def, maybe K def, N def and too much N...but why?

Please note, all plants are too short and stubby, small leaves.

Looks like it is revegging to me with all those single leaves

I wouldn't get drastic yet. Soils can be mixed inconsistently, especially commercial soils that are mixed in large batches. Aerifying your water is good practice. Make sure you're getting good runoff, or if you really suspect excess N, flush. Look for improvement in new growth.

BTW, these are not clones of blooming plants, right? Ozzie's observation about revegging fits. Good luck and keep us updated. -granger

OMG, could this be it? I get my clones from a friends friend and got a batch of it and some of the bigger ones were flowering...but the small ones were fine. He fucked up somehow. Could be, that he somehow did something with them and put them to flower when really young?
Or maybe hey are clones from flowering mother?

Not sure what will happen now if either of this, can I still get decent harvestin both cases? Dont know much about revegging, will look on the forum.

I run 24h light for the small ones now and 22h for the bigger, stubby now. I would know, if my lghts would went off unexpectedly. So this would happen when they were really young.

Thank you!

i have a couple of clones, although bigger than yours that went into flower once they had rooted and reverted back to veg throwing out single leaves like yours have, hence my observation. mine are back on track now on 18/6 light cycle....and yes their growth is stunted...
