I grow my plants in DWC buckets . My ladies have been doing fine in veg and 3 days ago while flowering the air pump was turned off for 1 day. the leaves started to get droopy and burns occur (i also changed the reservoir ) . The burn is getting worse so I lowered down the ppm . The Ph fluctuation is very crazy too , i have to moniter and adjust it everyday .

ph 5.8-6.5
Ec 1.2
Ppm 631


growing with 650W LED grow light
