advice on soil grow

hey just wanted some one to look over my set up, growing dutch passion brainstorm in a 3.5x3.3ft grow tent 6.5ft tall. using mixture of john innes sand and perlite, ph 6.5 ec will start at 1.0 after the nutes are gone from soil and raise them gradually using bio bizz grow and bloom, humidty kept at 60% at day and 30-40% night. temps 27c day and 22 night. have a fan outside tent which is blowing in fresh air as the windows are open 24/7 so co2 shouldnt be a problem. using a 600w hps also have a 250w mh if needed.

please let me know if iam missing some thing many thanks..

sounds legit to me.. pop some beans.

thanks man..

60% humidity might cause mold or PM issues later on depending on airflow and bud density etc. 27 is a little high for temp as it is 80 degrees but if that is the high, as in 75-80 not 80-85 then you should be fine. It all lookes good though. Happy growing and good luck.
