some of my plants, mainly the hyro and some long grass stuff, have brownish leaves and small holes in the leaves..any ideas how to fix it?
 
The pinholes sounds like textbook potassium deficiency, but traces could also be the culprit. Hygro is a great indicator plant since under good lighting and CO2 conditions grows extremely fast and will show deficiency symptoms much earlier than most plants (so you can catch it and fix the problem before slower growers become deficient).

What is your dosing schedule?
