to be honest I don't know, fellow i purchase supplies from said al long as ph stays relatively same no need to worry. I never had much trouble at all with any fluctuation in ph level. all of a sudden in last few weeks, bam. cant keep level up. ph of tap water is perfect going in tanks. Is this something to be concerned with this close to harvest?
GreenWeezil Reviewed by GreenWeezil on . ph problem? I had a quick drop in ph to about 4.0, changed water out, was good for couple of days then dropped again, fixed with additive for upping ph, then couple of days dropped again. plants are getting very close to harvest within a week or two. Any info would be great as to most of what i have read is problem with ph rising. I can't keep it up, whats the deal?:wtf: Rating: 5
