If you have 3 gal pots, flush with 9 gallons of water (not 3x the regular amount of water). If you have 1 gal pots, flush with 3 gallons of water, etc. And use properly ph'd water, and check the run-off.

You only need to flush once usually, don't do it everyday. Flushing or even watering everyday will definitely drown the plant. Let the soil properly dry out. Check with your finger or by lifting the pots and checking the weight.

Even though you might be overwatering, I'd say that at this point, it would be more detrimental to let all those nutrients sit in the soil and burn up your plants more. I don't think the overwatering will kill them as fast as all those nutes. Kind of the lesser of two evils here... but something needs to be done. :twocents:
