What deficiencies?

Hello With the colors it's showing id say calmag from the spots and yellowing between the veins, nitrogen from the low yellow leaves....but the whole edges of leaves are changing too which is often a sign something more than a deficiency is happening, like the ph is fluctuating too much or off entirely. If you're growing in coco it's needing to be watered fairly often...is it getting fed much? If it is then i would definitely look into whether your ph is in the right range.
