The plants are two weeks old . The meter i bought was not calculated I thought the pms was 300 . when i changed the water and found out the meter is wrong i figured i was at 900ppm.
I have now switched the water completely out and dropped my ppm to 250 and ph is at 5.5
so now the water i believe is were it should be but i am not sure how much to feed water to them.. and do i flush with just the straight water...
PS :
this is a hydro plant.
I am seeing very little change on them coming back. how lingwill it take to come back...should i cut off the dead leaves ??
