ph lock?

I mixed my nutes and water tested once got it to 5.8 same as always but I didn't lett it sit before testing I don't know what I was thinking fed my girls next day this is what I wake up too tested water and it was 7.5

also sprayed gognats the day before but never had this happen with gognats so I don't think it's that

I'm using foxfarm big bloom, grow big, microbe brew, and root drench at 1/2 strength temp never goes over 78

ph lockout takes days to show any effect, and you can flush your soil to remove that bad batch of water.That looks damage from wahtever you sprayed on them.

ok cool man thnk you so much the gals are doing good besides the spots no other signs of stress also there in 100% perlite hempy not soil

yeah bit of overspray.
