Can Any Gurus Diagnose, Please?

Hi all.

Glad to be a part of this forum. I haven't grown in about a decade and am now a cardholder and happily getting back going. I am attaching a couple of so-so pictures. I seem to have some yellowing and drooping going on in my plants. It seems to be an immobile issue, since I am seeing it systemically and on new growth rather than just old growth. But, what do I know? That's why I am asking. Any ideas from the photos? Nute lock out or burn? Overwatering? Deficiencies? I'll list my growing specs below. Hope y'all can help! Thanks and please just ask if you need more info/pictures.
OPU

4 weeks old
Transplanted from 1 gallon Coco Coir fed with advanced nutrients to 3 gallon Fox Farm Ocean 1 week ago
Temp at steady 79 degrees
Humidity at 30 - can't seem to get it higher even with a humidifier
5 x 5 x 7 secret Jardin tent
2 600 HPS 18 inches from plants
Water PH at 7.0 on watering
Getting acidic readouts below 5 in my run-off, but I heard that is somewhat normal in new Fox Farm Soil?
Strains pictured are Jack Frost and Apple Kush

PH too low. Should be closer to 6.5. They look over fertilized. Probably not overwatered unless they are actually sitting in a puddle of water. Prob only need to water once maybe twice a week at that size. I would check the runoff ppm(cheap if you dont have one, well worth it), if it is over 2500 flush the pots with fresh water until it drops. I know it is all the nutes coming out, but there may just be too many. I use ready grow "soilless" mix. Just like soil, but no food. I control it. You will have to water more often with the mix though.

why would you switch from coco to ff? Just curious really. IMO coco is such a better producer and i think that probably has a little to do with your problem since i assume your ph should have been between 5.5-6 in coco and now soil closer to 7 so seems it would shock the plant though i hae never done that myself.

I hae taken a plant a couple weeks eg in a dwc bucket to coco but that was fine.

I figure my PH might be off. However, it seems odd seeing as the FF soil is brand new and should be buffered. Rumor is it runs off acidic though. I am considering doing a flush just want to cover all bases first. Really hoping to just get a bead in on what the exact deficiency might be. Thanks for the input.

You could be right about shocking from transplanting. I went to soil from Coco because I got the plants from a friend and I have never grown in Coco but am familiar with soil to a degree. It's my first grow back from a long time and I wanted to use a somewhat familiar medium.
