I ended up having to wait a week for my nutes to arrive in the mail. I had them shipped and the shipper took their sweet ass time....anyway today I got some fox farm grow big (hydro formula 3-2-6) and also tiger bloom (for flowering). I emptied the res today and added about a gallon of spring water with grow big at about 1/3 strength. The spots on the leaves have gotten worse (see pics) and one of the plants has very curled leaves which I think is a phosphorus deficiency (again see pics) but needless to say none of my plants are in great shape. I should have my 250 HID in the mail any day now, it's an HPS ballast with a MH conversion bulb. so here are my questions:

1) Is it possible for these plants to bounce back? or should I scrap this grow and start over once I get my HID lamp?

2) what steps would you recommend I take from here? including nute schedule and when to start using the 250w HID. I am thinking I probably want the plants to show significant improvement before I jam them under an HID..

any help/suggestions would be greatly appreciated...thanks
