Is this ph burn or what????

hey everyone, just wanted to know if someone can tell me what wrong with my stuff...
ph is at 6.0, but the run off is like 6.3-6.4
or is it nute burn???

nutes, feeding schedule, soil mix ...

im using cutting edge solutions, i water once a day in rockwole...

are you using a cal/mag supplement? what's your pH?

yes i am, ph is 6.0

looks like ph imballance to me. need to flush. did you ph the rock wool before you started?

what should i set the ph at befor i flush????????
the run off is always like 6.3

to do a flush take straight ph`d water at about 6.5 or 7 ( nutral) and run about 2 to 3 times the amount of soil through it ( eg 1 gallon pot 2 to 3 gallons of water. then let it sit for about an hour or so to drain a bit then add a nute mix of what ever cycle your in ( flower or veg ). then let it dry for a while till the leaves almost droop. wet/ dry cycle is most important i use the weight method instead of the finger in the soil to see if it needs watering, its more accurate for me.

but then again i just realized you may be doing hydro. if so disregard my help on the flush. i dont do hydro i`m an old dirt lump myself it`s easier to deal with.
