Adjust ph by flushing?

spacecase · #1 (**permalink**) 06-29-2009, 06:09 AM

I think one of my plants is suffering symptoms from a high ph. It is only about 17 days old, but it has been growing pretty strong and still looks good except for the signs of an early deficiency.

question is, should I try to lower the ph gradually, even though the plant may get worse before it gets better?

or should i flush the plant with water around the recommended MJ ph level (mid 6's)? i read that flushing severely shocks the plant, and i know overwatering can be bad, so i don't want to risk the life of the plant if i don't have to.

u can use just ph balanced water about 2-5 times the amount of soil (1 gallon pots 2-5 gallon water) I just flushed mine because the ph runnoff was like 5, to the first 5 gallons of water -5 gallon pots..I added 2 tbsp dolemite lime to try and neutralize the ph then 5 gallons of water , then I added the reccomended nutes in one final gallon.
If your ph is the other way im not sure this will work...just what I did.
prolly just go with water
