Leaf/plant damage

[DiggytDank]

K, so over the past week 2 of my plants have been showing signs of major leaf damage, large fan leafs, and little new leafs, they look like a large bug has just been taking bites out of the plant, but i have searched and searched, no bugs, so i thinking its some kind of deficiency, but i could not find any similarities in any of the books i have, PLS help, all input helps

How about some more info? Lights, nutes, indoor/outdoor, Soil, age, ect...?

they are in green houses, and are soil, they get food every other watering, they are 4 months old. they spent time inside before they moved to the green houses. I have 6 of that strain going, and 2 of them are showing these symptoms, all of the plants get the same nutrients. i just cant figure why only 2 of them are doing this. any idea's?

how long have they been in the greenhouse?

are the two affected in different environments, even subtly? are they a bit more exposed - not shielded by other plants?

I have the problem and someone told me to use epsom salts in the water because lack of potassium

For the white spots check under the leaves for spidermites..they're VERY small.
There is also a good pic chart in FAQ... go to plant problems...then to nute/ph problem, then to plant abuse...its the second up from bottom Neitzshe ?? something like that...also in water nute & additives, then to nute formulations, then how do I find out... hope these help...LUCK

Check FAQ...I think thats for magnesium...I may be wrong, but check the above mentioned charts.

that's not a Mg deficiency, but that's what you would use Epsom salts for.

I'd bet this is climate shock.
