Runoff 6.0 is too low. You are looking for runoff 6.7.
In an emergency, cider vinegar or lemon juice work okay.

Following the instructions for a correct flush (stickied at the top of this section), you must:
-Aim for final runoff 6.7 in soil, 6.4 in soilless, and 6.0 in rockwool
-Feed immediately with a complete fertilizer mixed at 1/4-1/2 strength that contains micronutes to replace what you have washed out through flushing.
stinkyattic Reviewed by stinkyattic on . Poor plants in bad shape, and I dont know whats wrong. OK I am "calling all cars" - I need some serious help. I have no clue what wrong with this crop. :( See pics below. I am raising them identically to my last crop which is flowering but looks pretty good. These look so sad. wtf4: I checked PH and it looks alittle high, on or above 7.0 so last night I added a sqeeze of lemon juice and 1 tsp of epson salt to help the PH and add some MG. They are in an airconditioned closet in my garage, HPS lighting 400 watt, and ventaliation fans. Rating: 5
