First grow... some problems

First time grow and have currently got 3 Reserva Privada Sour Diesel Plants under a 250w ecobulb. Pics will follow and would greatly appreciate any help with my grow as one of the plants looks a bit worse for wear.

Only have a 4inch intake fan and an 8 inch exhaust fan at the minute and also heard from a good friend that temps may be an issue, we intend to get an 8 inch intake fan as well as a desktop fan mounted on our wall

Quick question for you guys...Indoor grow in homemade grow box...
Will be running pro-mix soil...
Would it be better for me to run the pro-mix soil mixed with a manure fertilizer with coffee grinds and add nutes to the flowering cycle only...or would it be better to grow in just the pro-mix soil and add nutes throughou the whole grow? Want to try to keep it as cheap as possible with the least amount of human interference...otherwords, self-sufficient as much as possible...
Any help is greatly appreciated...
Thanks
 
Plants seem to be doing a lot better now. Haven't been feeding them as much and got a 9" desktop fan to help circulate air around the room. Pics Will follow
 
More Pics of the plants today, they are looking a good bit healthier since i got a desktop fan and stopped watering them as much some pics attatched, one of the three still looks quite worrying
