Some of the nutritient deficiencies in mature plants are generally observed in lower leaves first.

The leaves in the first post shows all the symptoms of Potassium deficiency except a single one.

- Chlorosis (yellowing) between veins and leaf margins - starting from the leaf tips *

- Necrosis [tissue death, brown spots ("firing") or holes etc.] following chlorosis

- * Curling of leaf tips towards the underside of lamina (this is generally where it starts, see the photo below). This endmost listed symptom is not observable from your photos in the first post of the thread. May be the tips are already died and fell off.

We have received some calls recently in regards to the tips of leaves yellowing and some of the leaf tissue at the tip of the leaf drying up (click here for photo "below"). This is potassium (K) deficiency, which can be seen sometimes when the plant is growing rapidly at about the topping stage. This is not necessarily an indication that more K is needed. When the plant is growing rapidly, it sometimes can’t take up all the K it needs.

Poor root development and low soil pH can restrict uptake of potassium. Upper leaves pull potassium from lower leaves causing leaf tip yellowing and breakdown. As tobacco begins to grow rapidly at about mid-season symptoms may be more pronounced as growth and potassium demand increase and out pace potassium uptake.

I do not know what it is but I did find it on a few of the havanas. I have picked all of the leaves with damage off and will watch and see what happens next unless there is something I need to be doing now

I am soaking soil from three different rows and as soon as my boy gets back I will test the PH of the soil

Ok I finished up my PH testing and came up with The area where the damage is the worse is sitting at 6.9 and the rows on the west side are 6.5. So my question is this a good PH range or do I need to adjust the PH. I have found several new brown holes in several leaves that where not there yesterday or at least I do not remember them having holes.
