So got a weird problem and the first in a long time, kind of stumped. Have these 4 cuttings vegged up and in mid bloom, same feed. Two are showing serious phosphorous deficiency/toxicity? Older leaves accelerated necrosis, two plants are perfectly fine. Pics attached , first two the good, last two the ugly but I hope they don’t turn out bad lol

Need better pics of the lower leaves.

P deficiency is quite an easy one to diagnose. The bottoms begin to pale before going a distinct grey/brown colour and go crispy. Don’t see that from pictures you’ve shown
 
All honesty get some better lighting. With the yellow coloring on photos ,hard to tell what real colors are. Re do photos and make sure it is using white light so the colors show true.
