Looks like my plant when I accidentally watered with too high of a ph. The only other deficiency that looks even remotely like would be calcium. Generally, soil growers don't have many calcium problems unless it is from ph lockout, feeding too much phosphorus I believe, or if you use RO water. It could also be where water may have spilled on the leaf and possibly burnt it or even from overwatering as the plant does seem a bit droopy. It could even be from feeding too much as the leaves do seem rather dark and the tips in one of the pic are burnt. I would start off digging up a small chunk of soil and mixing it with an equal part of RO water or tap water if your ph is close to 7. Then once mixed test the ph with a ph meter and see where it lies. If the PH reading you get is under 6.2 or over 6.8 you might need to flush. How often do you water? Do you feed every time you water or on a schedule? If you have an EC/PPM meter I would check the runoff EC/PPM if you do a flush.
