OK, I am totaly new to hydroponics. I have a ton of money invested here and need help getting this set up right for he plants i have going now are just bag seed for trial run. I started out from seed, used 2x2 inch rockwool cubes to start. Then put them in a home made DWC set up. Used a 600 watt HPS light at first but have since switched to a 600 watt MH conversion buld. Its a solarmax brand bulb. I have switched from the DWC to a 3x3 foot flood table set up i purchased from the local hydro store. I have been using the "Recipe for Success" kit i also purchased from the local hydro store. It consits of BC grow and BC boost, Thrive in the red bottle, Magical, Root 66, and sugar daddy. I used this at full strength for the flood table. The plants are just over 3 weeks old in the flood table. My grow room is a 10x4x8 area split in half . Use half for veg and half is waiting to be used to flower. I have a 500 cfm exhaust fan pulling air from both sides and vented to the outside. I have a 250 cfm inline duct fan pulling air into the room from a cold air duct from furnace. The room is totaly covered with black 6mil polly, so the room is pretty well sealed up. My 600 watt lamp is about 18 inches from top of plants. I flood the table 3 times a day for 5 mins each time. I put the 2x2 rockwool plants in a 3.75 inch net pot and cover the top of the pot with clay pellet. The flod tray is also filled with clay pellets. I have the cups sitting on the tray and the pellets surrounding the pots. When i checked them yesterday some of the plants look really burnt and shriveled up. A couple of them are still looking good but the root system on all of them is not all that great. I posted pics and tried to be as detailed as possible. I am wondering if this is nute burn or light burn? My temps run high in the room, 85 degrees most of the time wth lights on. The lights run 18 on 6 off, fans run constantly. any input here would definatly be appreciated. Want to get the good seeds going ASAP!
