Air pump to what went out? Do you mean that your fan went out and the plants got heat stressed? Or did an air pump for reservoir aeration went out, and the nutrients were stagnant? (I can't tell if those plants are in soil.) Whichever it is those plants look fried. If it's not heat stress I highly recommend flushing those plants well, then starting again with about half the nutrients you are using now.

Also I think you could do what you are trying, and still leave the fan leaves on the plants. The plants would probably be much more healthy, and you can always cut them off at harvest and nobody would know the difference.

Looking forward to the end result.
