    I left my hydro system for 4-5 days I come bak and ph is 5.7 and ppm is 550. Also it's their first week of flower. There are 9 plants under a 900w hps.

    I've never heard of a 900w hps. Did u mean 600w?

    When was the last time you calibrated your ph and/or ppm meter(s)?

    When I first bought it so like a month and a half ago. I also though nute burn started on the tips of the leafs. I was really convinced this was calcium deficiency but u guys have me scared.

    Recalibrate it, just to be certain that its ok. I know, from firsthand experience, that a ph meter being off can wreak havoc on your grow.
