i have a ebb and flow table,first time hydro,thats in perlite and just covered with a layer of clay pellets to hold the pots from floating,ph 5.7-6.2,nutrients 0.2-0.3 EC ,thats 100-130ppms on a bluelab meter,iv been growing for 2 years in soil but never had problems like these, it starts on the lower leaves so i thought its a deficiency but i dont know what it looks like rust,they are 7 days in veg. clones from a white russian plant,iv been adjusting the ph from 6.3 to 5.2-5.4 for 3 days in a row is that maube too much oscilating for them,the water seems to be very easy to ph up or down meaning its not buffering almost at all couse im using a ro filter so i was thinking maybe i shoild mix half tap water half ro
