Hey bro, I got that veg/bloom/fish mix stuff, check out the bottles in my gallery and those will last me a few grows easily... Also i found dolmite lime is a must or lime whatever to keep the PHG neutral. I had lots of problems with my PH bouncing around. Also do not start feeding the seedlings nutrients or over watering when you start out that also causes problems... and i literally thought all mine were yellow and going to die and they made it and are looking better than ever.. That 400 watt balast try get one that you can use for Metal Halide and High Pressure Sodium. MH for Veg and HPS for Flowering.. And i used 5litre bags for my plants and 2litre ones in the start easier than pots when it comes to transplant. Also make sure your soil for your seedlings does not have added nutrients that may be too strong.. start off with a seed mix. Lots of stuff just remembering what i can about my grow while its still fresh.
