late start S.S grow.

hey i wanted to do this years grow using sub's SS, but i am starting really late. its already july 11 and i havent even mixed the soil. so what i was thinkin of doing is start my plants off on liquid nutrients until the soil is ready (in 30 days) and then when i transplant them to the SS, i was thinking of putting almost only SS into the pots. i was also thinking of taking out some of the blood meal since they wont be needing as much nitrogen....any input??? thanks if you can help.
