Holes In Leaves

[discus dreamer]

Help!!
Bought a new bottle of Plantamin and instead of just adding about 10 ml to my 200L tank during a 15% water change I put about 40ml in as I hadn't added any for about 4 weeks, this is still less than it recommends although the instructions are a bit ambiguous. Very soon afterwards my previously healthy plants were looking terrible. They have small holes in a regular pattern such that the amazon swords look like they are made of lace. My book says this could be lack of magnesium. Any ideas about what I could do now, do I just take the worst affected plants out and get new ones? Should i do a big water change before adding any new plants? They were looking great before so i am really fed up about this. My little tank is doing fine with just an innaccurate squirt of fertilizer when I change the water.
Details about the big tank
It is an Aqua One 39 x15 x 23 (water depth), I have sand and then gravel and a mixed community of fish, external canister filtration and Co2 injection. The lighting is 1x30w tripower and 1x30w super light.
thanks for any help

Sounds like something a bristlenose would do
What fish are in the tank?

No it's not the fish, I do have a green pleco and a siamese flying fox but the plant damage is too regular for fish or snails it is holes between all the veins of the plants. But thanks for the warning about bristlenoses.
