i just got a test kit and found my ph is high off the chart. my plants started turning yellow and light green and some have brown spots some are curling up, some are curling down. but there not that bad, looks like they can all be saved still can this all be from the ph? i'm in soil mixed with perlite i have been using very little miracle grow every other feeding (no more my n2 was way high too) i got advanced nutes now.thanks
