my plants are fine but i been through the sick thing before but fixed it with no problem im using bubbleponic system but also using dirt as well at my other house so i know a little something not saying im a pro but doesn't take alot to grow just plant, feed, and get it light just the over feed or water them, its just like you eating food,if you put too much salt on your food will you eat it and keep it eating i dont think so you will try to fix it, always start with very little food that way you can add more when you need to but if you put too much its hard to take it back
