Help! PPM issue

I set up my floranova grow nutrients around 200ppm for my 2 week old plants. It runs through twice and will have tripled to 600ppm. Can anyone help me? I have my plants set up in rock wool in a flood and drain system. I'm afraid im gonna burn my plants to death if this keeps happening.

How much Floranova did you add per gal. of water? are you using reverse osmosis or city/well water? What is the p.p.m. of your water before adding nutrients? If you did less than half strength of what it recomends you should be good bro. I use 1/2 tsp. per gallon for the first week then bump up to 1 tsp. per gallon for the rest of veg. You need to really watch your plants and let them tell you what they like. If you arent getting any brown tips you should be fine. If your plants appear to be nute burned then I would reccomend flushing with clean water and adding your nutrients again at a lower dose.
