Zinc deficiency

Here's the deal...I think it is some kind of deficiency of some sort...but those are hard to pin down exactly without being there and doing everything ones self...so noone wants to guess at what you should add, and then you add it and that wasn't the right thing...But here is what I would do...alot of google plant deficiency searches and then I would find the one that best fits your problem and give that solution a shot...I would also flush the plants and make sure everything added back was perfectly measured and such not...

Grumpy is right on, I copied this from International Cannagraphic:

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.


Soil

Zinc gets locked out of soil growing at ph levels of 4.5-4.7, 7.5-9.5
Zinc absorbed best in soil at a ph level of 5.0-7.0 (Wouldn’t recommend having a soil ph of over 7.0 in soil) Anything out of the ranges listed will contribute to a Zinc Deficiency.
