CHEESE
This one I believe was suffering from and zinc lockout due to a constant pH of 6.0 and according to this I found on a different forum:
Zinc deficiencies on some plants will have the Spotting and bleached spots (chlorosis) between the veins first appears on the older leaves first, and then goes on to the immature leaves. It will then start to slowly affect tips of growing points of the plants. When the zinc deficiency happens so suddenly, the spotting can appear to be the same symptoms to that of an iron and manganese, without the seeing the little leaf symptom.
Zinc is not mobile in plants so the symptoms will occur mainly in the newer growths. Having a plant that is deficiency in Zinc can cause small crops, short shoots and have a cluster of small distorted leaves near the tips. Between the veins (Interveinal) yellowing is often combined with overall paleness. Pale or grayish, yellowing between the veins; rosetted weak is the signs of a Zinc deficiency.
With a low level of zinc in your plants, your yields will be dramatically reduced.
Interveinal chlorosis is present in the small, narrow distorted leaves at the ends of really shortened shoots and the shortening between internodes. Leaf margins are often distorted or wrinkled. These nutrients will get locked out due to high pH: Zinc, Iron, and Manganese. These deficiencies will often occur together. Parts affected by a zinc deficiency are young leaves and petioles.
Having an excess of Zinc is very rare, but when it does happen it can cause wilting and in worse cases death.
Problems with Zinc being locked out by PH troubles
High ph, Low organic matter, High Phosphorus levels in the soil, and or lack of nitrogen.
Hydro and Soil less Mediums
Zinc gets locked out of Hydro and Soil less Mediums at ph levels of 5.7-8.5

Zinc is absorbed best in Hydro and Soil less Mediums at ph levels of 4.0-5.5 (Wouldnt recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Zinc Deficiency.
The symptoms seemed consistent with what Cheese was experiencing, I just hope she will do better now that I have lowered her pH to 5.5. Oh, and as you can see in the photos she has continued to produce numerous 'normal' pot leaves, of which I am very proud.
